Ask the contractor if any corrective action has been taken based on quality control test data for the period when the acceptance sample was taken. The current assessment included insights from stakeholders collected in a series of distributed engagement meetings that confirm its relevance and significance for local decision-makers; examples include a Northeast Listening Session in West Virginia, a kickoff meeting in New York City, and New York City Panel on Climate Change meetings. "[129][clarification needed] For one, green roofs have over double the lifespan of a conventional roof, effectively decelerating the amount of roof replacements every year. Caltrans field laboratories meet the re:source requirements when Caltrans central materials laboratory meets the requirement. Make sure that the proposed job mix formula is verified by the district materials laboratory within 20 days of sampling HMA or when requested in writing by the contractor or within 3 days of sampling rubberized HMA. The sample is considered failed when two of the three split samples fail or when the engineers split sample fails and any of the remaining two split samples tests are not yet reported. Building Resilience to Climate Change: Ecosystem-Based Adaptation and Lessons From the Field, A. . Prez, B. Fernndez, H., and R. Gatti, C., Eds., IUCN, International Union for Conservation of Nature, 73-87. Under the SPF process, for non-pay factor quality characteristics, follow the guidance in Section 4-3904A (5), Monitoring Non-Pay Factor Quality Characteristics Using Statistical Pay Factor Specifications of this manual.

Rosenzweig, Solecki, W., DeGaetano, A., O'Grady, M., Hassol, S., and Grabhorn, P., Eds., Blackwell Publishing, 649. Farther south, New York City has taken numerous steps to implement PlaNYC, a far-reaching sustainability plan for the city, including amending the construction code and the zoning laws and the implementation of measures focused on developing adaptation strategies to protect the Citys public and private infrastructure from the effects of climate change;26 some major investments in protection have even been conceptualized. Practices available to pavement managers, designers, and specification developers that can be used to reduce peak pavement temperatures and might be used to address UHI issues are discussed in Chapter 6 (.pdf) of the Reference Document. 2011; Wolfe et al. HMA is placed using one of two specified quality assurance processes: The standard process or statistical pay factor (SPF) process. As soon as it warms back up to 70 degrees F, the tire pressure will be back to the specified 100 PSI. Most quality characteristics are sampled and tested once per sublot. United States. The threshold requires the quality factor to be 0.90 or greater, which is also expressed as a PWL of 70 percent or greater. URL When a pneumatic-tire roller is specified for compaction, the speed does not exceed 5 miles per hour. [55] Several studies have revealed increases in the severity of the effect of heat islands with the progress of climate change. The resident engineer must report the test results to the contractor within 5 business days of sampling. URL Warmer winters and less snow cover in recent years have contributed to increased deer populations62 that degrade forest understory vegetation.82, As ocean temperatures continue to rise, the range of suitable habitat for many commercially important fish and shellfish species is projected to shift northward.

", American Academy of Orthopaedic Surgeons: "Heat Injury and Heat Exhaustion. It is noted that pavement albedo changes with time, with the albedo of concrete pavements getting lower and those of asphalt pavements increasing as they age (see figure 3). As asphalt is spread, it releases some of that heat, which is why its often best to leave this work to the pros; even getting too close to asphalt can mean burns, sinus irritations, and other hazards. If the contract includes prepaving grinding: Emphasize that prepaving grinding work is only applicable to existing asphalt concrete surfaces that have not been cold planed or replaced. Thermal emittance, thermal conductivity, and specific heat capacity of the materials are second order factors (Li et al. DTFH61-12-C-00016. For Caltrans acceptance sampling and testing, test at the frequency shown in Section 6-1, Sample Types and Frequencies, of this manual. Receiving notification from the contractor at least 2 business days before sampling material so that an inspector may be present during the sampling. Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Billion Dollar Weather/Climate Disasters, List of Events. If the trucks are tarped, record that information on Form CEM-3501, Hot Mix Asphalt Production Report.. Make sure the contractor constructs a temporary joint taper between the existing pavement and any newly placed paving or cold planing area when a transverse joint greater than 0.04 foot cannot be avoided before opening to traffic. When the SPF process is specified, discuss the three-day look-ahead HMA production and paving schedule submittal. It is the ratio of heat flux (power per unit area) to temperature gradient, and is expressed in units of W/mK. WMA technologies allow production plants to produce HMA at Fahrenheit temperatures 45 degrees to 85 degrees lower than the traditional mixing temperature. A. . Prez, B. Fernndez, H., and R. Gatti, C., Eds. During winter, frequent storms bring bitter cold and frozen precipitation, especially to the north. Of the 12 states in the Northeast, 11 have developed adaptation plans for several sectors and 10 have released, or plan to release, statewide adaptation plans.102 Given the interconnectedness of climate change impacts and adaptation, multi-state coordination could help to ensure that information is shared efficiently and that emissions reduction and adaptation strategies do not operate at cross-purposes. 01. Public and private citizens or institutions who service and anticipate a role in maintaining support for vulnerable populations in Northeast cities and communities indicated that they are making plans to judge the demand for adaptation services. Increased temperatures, causing warmer winter conditions, made the city more similar in climate to the more northerly wildland habitat of the species. For guidance on addressing noncompliant material placed using the standard process, refer to Section 4-3904A (1), Acceptance Test Results Outside Specified Limits on Non-Statistical Pay Factor Projects, of this manual. The quality characteristic acceptance test limits for aggregate properties are based on untreated aggregates. 1990. The presence of non-native species is heavily dependent on the amount of human activity. 2014. URL Heat islands for various areas of development (EPA 2003). If the sand equivalent test result exceeds the specified limits, immediately notify the resident engineer. Under the SPF process, the contractor performs quality control inspection, sampling and testing. | Detail , ,, 2013: Billion Dollar Weather/Climate Disasters, List of Events. Identify the stationing from which samples were taken and the area they represent, for example, lane #1, first layer. Label the samples with enough information that the exact location HMA was placed can be identified if it is rejected and has to be removed. If notified by the contractor that an existing asphalt concrete surface cannot be corrected by prepaving grinding, respond within 5 business days with agreement or disagreement. The contractor may not use this core as part of their reported quality control testing. URL And you simply do not know where in the cycle you are checking the tire pressure. The most efficient pugmill mixing occurs when the material level remains at the top of the paddles along the length of the mixer. | Detail , Kuntz, J., and R. Murray, 2009: Predictability of swimming prohibitions by observational parameters: A proactive public health policy, Stamford, Connecticut, 1989-2004. 25: Coasts, Key Message 4).

The contractor takes the following steps related to job mix formula verification for all types of mixes. Consult with the district materials engineer and either the Division of Maintenance Office of Asphalt Pavements, the districts construction field coordinator, or both, about acceptance of the contractors proposal. Using the unit price adjustment equation, if the composite quality factor is 1.05, the contractor earns a 5 percent incentive, or if the composite quality factor is 0.95, the contractor earns 5 percent less, which is a disincentive. Document any locations that may cause smoothness issues if left unaddressed. T.R. If windrowing is used, prevent overcooling of the HMA by not allowing excessive windrowing. Researchers have also noted that the spread of impervious surfaces is correlated with low socioeconomic status neighborhoods across various U.S. cities and states. Surfaces in the urban areas tend to warm faster than those of the surrounding rural areas. If the project has not been assigned a structure representative, coordinate the review with the bridge construction engineer. Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Albedo (or solar reflectance) is a measure of the ability of a surface to reflect solar radiation. [83], The temperature difference between urban areas and the surrounding suburban or rural areas can be as much as 5C (9.0F). Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. This decreases the albedo of the city and thereby magnifies the heating effect. [134] Several other studies have observed the urban cool island in semi-arid or arid regions. Various regional assessments were also consulted to capture key issues, concerns and opportunities in the region with particular focus on managed (agriculture and fisheries) and unmanaged (ecosystems) systems (for example, Buonaiuto et al. US EPA." They described this unequal distribution of trees as a demand for "luxury," rather than "necessity. And try to avoid working on sunny days when the temperature is above 90 degrees. | Detail , ,, 2009: Coastal Sensitivity to Sea-Level Rise: A Focus on the Mid-Atlantic Region. The medical definition of heat stroke is a core body temperature greater than 104 F, with complications involving the central nervous system that occur after exposure to high temperatures. Live Green Toronto, n.d. Karl, Melillo, J.T., and Peterson, T.C., Eds. | Detail , Zimmerman, R., and C. Faris, 2010: Infrastructure impacts and adaptation challenges. Any new or revised data is highlighted. A researcher found that high UHI intensity correlates with increased concentrations of air pollutants that gathered at night, which can affect the next day's air quality. The contractor then pays the independent third party testing costs. Do not use profiles provided with the bid documents. Sea level rise along most of the coastal Northeast is expected to exceed the global average rise due to local land subsidence, with the possibility of even greater regional sea level rise if the Gulf Stream weakens as some models suggest.6,13 Sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the Northeast.14,15. Labels each aggregate sample with the contract number, date, type of mix, aggregate gradation, aggregate source, HMA producer, and producers mix identification number. The Chesapeake Bay is the largest U.S. estuary, with a drainage basin that extends over six states. Caltrans pays for the independent third-party testing costs. United States Summary and State Data. 843846. Lawrence Berkeley National Laboratory, Berkeley, CA. Do not attempt to time the sampling of the HMA with the locations the cores are to be obtained. Determine whether resolution of AASHTO T 209, Method A is necessary and sufficient to resolve issues with percent theoretical maximum density or design air void content. In the transportation sector (see also Ch. Once verified, adjust each lot based on its own contractor quality control test results. - Damage to mud flaps and mud flap hangers takes a toll with fleets of all sizes. Suggested levels of field inspection for typical concrete pavement activities are: Guidance for quality control activities included in this section is summarized as follows: http://aashtoresource.org/aap/accreditation-directory. Fan air over the patient while wetting their skin with water from a sponge or garden hose. If the total layer thickness is at least 0.15 foot, the contractor is required to conduct density testing. URL Most nonmetallic surfaces have thermal emittances in the range of 0.80 to 0.95. If No ones ever really ready for winter to move inthe cold weather, snow and wind that hurts your face, not to mention the slush and Technology has been propelling human innovation since our first ancestors picked up a bone and used it as a hammer. Having said that, you need to be aware that cold weather can create a different challenge. If the adjustment failed to resolve the job mix formula verification problem, the contractor may propose a new job mix formula or dispute Caltrans test results in accordance with Section 39-2.01A(4)(i)(iv), Dispute Resolution, of the Standard Specifications. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day. At home, draw your curtains, shades, or blinds during the hottest part of the day, and open windows at night on two sides of your building to create cross-ventilation. Both parties to examine results of tests performed on split sample material. Examples of this include the grey-headed flying fox (Pteropus poliocephalus) and the common house gecko (Hemidactylus frenatus). Asphalt built-up roofs (BUR), by comparison, reflect 6 percent to 26 percent of solar radiation. Determine if crack sealing or dig outs remove and replace existing pavement are required to repair small areas. Figure 16.2: This will affect the regions vulnerable populations, infrastructure, agriculture, and ecosystems. If split samples of the material tests being disputed are not available, the third party uses any available material representing the disputed HMA for evaluation. Every year in the U.S. 15% of energy goes towards the air conditioning of buildings in these urban heat islands. Verifies that the contractor is adjusting the HMA plant controller based on the contractors aggregate moisture quality control test results. Cornell University Press, 200 pp. Although urban heat islands (UHIs) are most often thought of as existing in the atmosphere above the city, they actually exist at many different levels, including at the ground/pavement surface, in the air just above the surface (near-surface), and in the ambient air temperatures well above street level, as well as in the atmosphere above the city. If the contractors quality control test for a single non-pay factor quality characteristic falls out of specification two consecutive times, or any non-pay factor quality characteristic fails 3 times in a single day, the contractor must stop production, notify the engineer and demonstrate compliance before continuing production. For each day of aggregate lime treatment, obtain the treatment data log electronically for the resident engineers project file. For every square foot of green roof used in one study the savings amounted to $5.80 energy-wise. Suitable habitat for the Asian Tiger Mosquito, which can transmit West Nile and other vector-borne diseases, is expected to increase in the Northeast from the current 5% to 16% in the next two decades and from 43% to 49% by the end of the century, exposing more than 30 million people to the threat of dense infestations by this species.48. The paving inspector records straightedge measurements on Form CEM-4601, Assistant Resident Engineers Daily Report, and notifies the contractor of all out-of-specification areas. https://dot.ca.gov/programs/construction/training. Make sure that data required in the liquid antistrip treatment section of the special provisions is entered into the production units treatment data log and submitted in the required format.

Samples must be in four 1-quart cylindrical cans with open top friction lids. URL At the engineers option, noncompliant material may be accepted based on the engineer's evaluation of the effectiveness of your corrective actions. In a case study of the Los Angeles Basin, simulations showed that even when trees are not strategically placed in these urban heat islands, they can still aid in minimization of pollutants and energy reduction. Discuss the requirement to submit calculations for minimum spray rates required to achieve the minimum residual rate before the tack coat is applied. Even if you do manage to lay and compact asphalt in rainy weather, that material might then crack or split, and potholes will form sooner rather than later. Hot mix asphalt aggregate lime treatmentslurry method, Hot mix asphalt aggregate lime treatmentdry lime method, Verify with the district weights and measures coordinator that the proposed lime treatment plant is Caltrans-qualified in accordance with the. (Missing url), "About." Windrow temperatures can be monitored with an infrared heat gun. The more southern states within the region, including Delaware and Maryland, have a highly vulnerable land area because of a higher rate of sea level rise and relatively flat coastlines compared to the northern tier. When the HMA is run through the material transfer vehicle, paver, or both, the mat temperature may be above the minimum specified breakdown temperature. Are overabundant deer herds in the eastern United States creating alternative stable states in forest plant communities? For samples that will be shipped to the district material laboratory or field construction laboratory for testing, complete Form TL-0101, Sample Identification Card.
