model of the environmental effects on pavement temperature. The asphalt concrete pavement temperature is required as one of the input variables to the performance model being developed by the Strategic Highway Research Program (SHRP). It is also required for both the SHRP asphalt binder and asphalt-aggregate mixture specifications.

tions occurred from high temperatures in the pavement. One of them is the use of thermally conductive materi-als in order to improve the resistance of pavement to the adverse effect of high temperature. Du and Wang (2015) showed that using graphite in asphalt mixture can suc-cessfully transmit the temperature to the bottom layers.

The effect of cooling cycles on the low temperature behavior of asphalt concrete mixtures is investigated using a recently developed acoustic emission (AE) test device. In an attempt to link the local AE response of the asphalt mixtures to the pavement global response obtained through mechanical tests, the AE-based results were validated using traditional mechanical pavement …

In addition, pavement surface temperature is directly related to the roadway safety and environmental issues such as formation of ice during winter and urban heat island effect during summer. This study investigates the feasibility of mitigating temperature-related issues on asphalt pavement by controlling thermal properties of asphalt concrete.

with daily air and pavement temperatures, initial temperature gradients, stiffness modulus, tensile strength. values, and thermal properties of the asphalt concrete layers as inputs. From the COLD model, it was. 19 determined that effects due to aggregate type were small compared to effects due to asphalt viscosity.

Asphalt concrete (AC) pavements in cold regions are prone to thermal cracking. There are two theories to explain this. The first one is that at some low temper-ature, the thermal stress in the pavement structure exceeds the tensile strength of the mixture, usually in …

Abstract. Proceedings of the Geo-Shanghai 2014 International Conference, held in Shanghai, China, May 26-28, 2014. GSP 239 contains 42 technical papers which focus on paving material characterization and modeling, pavement evaluation, analysis, and construction, and pavement base and subgrade.

– For asphalt cements: The dispersion of the relatively aromatic, polar, associating molecules in a less aromatic, less polar solvent phase. – For Polymer Modified Asphalt Cements: The extent of dispersion between the asphalt cement and the modifier. This determines to a large extent the physical properties of the binder.

This software is capable of predicting the outlet fluid temperature and temperature distributions within the pavement structure. Furthermore, large-scale physical models of the PES were designed and constructed to compare the performance of the thermally modified pavement structures with those of conventional ones and also to validate the model.

From the simulation results, it is concluded that adding graphite into asphalt mixture mitigates the urban heat island effect during summer by dropping the maximum surface temperatures of both pavement and bridge (3.1ºC and 1.9ºC, respectively, with 4.8% graphite), and the graphite modified asphalt concrete can reduce the use of deicing ...

use of RAS, GTR-modified binders, and ed cold mix bases had a direct effect on the temperature predictions, warranting further investigation. A subsequent analysis of the built pavements established that the use of these sustainable technologies affected the thermal properties of asphalt concrete pavements, which could impact the structural and

There are three main properties that have a big effect on pavement temperatures: solar reflectance, thermal emittance, and permeability. Solar reflectance. Solar reflectance is the percentage of solar energy reflected by a surface. Conventional paving materials such as asphalt and concrete have solar reflectances of 5 to 40 percent.

The reduction in aging effects greatly increases the life of the pavement and, ultimately, reduces the life cycle cost of the pavement structure. TEMPERATURE SUSCEPTIBILITY. One of the advantages of using SBR Latex Polymers is the reduction in the temperature susceptibility. At high temperatures, the modified binder shows much higher stiffness.

It was found that asphalt pavements with flexible bases, such as crushed stone, crushed stone mixing with 2% cement and Asphalt Treated granular Base (ATB), performed well under large temperature changes. Flexible base was, therefore, recommended for asphalt pavement in cold areas, high latitude zones and districts with large temperature changes.

Nanoparticles have been widely adopted to improve the high-temperature performance of asphalt binder. However, the influence of moisture on high-temperature performance is not clear. Hence, the water absorption performance of the nano-SiO₂-modified asphalt concrete is investigated. Based on this, to further analyze the pavement performance of the nano …

The graphite modified HMA also has 1.5 °C lower maximum pavement surface temperature than the non-modified HMA in the simulation for a summer day at Texas. This implies that the modified HMA with improved thermal conductivity, such as the graphite modified one, is effective in mitigating thermal cracking, rutting and urban heat island effect.

There are some distresses in asphalt pavements such as high temperature permanent deformation (rutting), low-temperature (thermal) cracking, and load-associated fatigue cracking. Rutting is caused by the accumulated plastic deformation (flow) in the asphalt mixture with repeated application of loads at upper pavement service temperatures.
