Abstract: Black-top asphalt pavements can develop high surface temperatures during summers, due to
heat gain from solar radiation, as well as due to heat fluxes from vehicular traffic. Urban heat
island effect and rutting are two major problems that occur due to rise in surface temperature
of asphalt pavements. This study investigates the potential use of Phase Change Material
(PCM) to curtail the rise in temperature of asphalt pavements. PCM has high heat of fusion.
In this study, PCM was used, instead of filler material, and was mixed thoroughly with
aggregates in melted form. PCM was mixed in three different proportions using cold mix
technology. Commonly available Marshall stability test was conducted to investigate the
feasibility of mixing PCM. Indoor solar simulation test indicated lesser rise in surface
temperature of the PCM mixed specimen, as compared to the control sample. Top portions of
the sample sets showed a difference of 8.87°C and middle portions a difference of 3.31°C.
PCM proved to be promising in reducing the surface temperature of asphalt pavement.
