Increased pavement temperature leads to urban heat island effect and thermal distress in pavements. The reduction in pavement temperature reduces the risk of thermal cracks in pavements and also contributes to the mitigation of the urban heat island effect. The primary aim of this study is to analyze the effect of incorporating PVC-glass mix on the thermal and mechanical properties of cement concrete pavements. The PVC-glass mix was incorporated as partial replacement to fine aggregates, at different replacement dosages, and is compared based on their mechanical strength. Results indicate that the PVC-glass mix can be incorporated in concrete pavements without compromising the mechanical strength up to 20% replacement dosage. Moreover, with an increase in PVC-glass mix dosage, a reduction in pavement temperature was observed. A peak reduction of 7.3˚C in the pavement surface temperature was observed with a 20% replacement of fine aggregate with PVC-glass mix.

路面温度升高会导致城市热岛效应和路面热灾。路面温度的降低降低了路面热裂的风险，也有助于缓解城市热岛效应。这项研究的主要目的是分析掺入PVC玻璃混合物对水泥混凝土路面的热和机械性能的影响。以不同的替代剂量将PVC玻璃混合物作为部分替代品掺入细骨料中，并根据其机械强度进行比较。结果表明，PVC-玻璃混合物可以掺入混凝土路面中，而不会损害高达20％的替代剂量的机械强度。此外，随着PVC-玻璃混合物剂量的增加，观察到路面温度的降低。峰值降低7。
