TLDR
In this paper, the thermal properties of PCC and PCPC were investigated with specially designed tests in a series of simulation experiments in the laboratory and the results showed that PCC is one of the most effective solutions for mitigating thermal discomforts in hot climates.Abstract:
Impermeable pavements are recognised as one of the biggest contributors to the urban heat island effect, because they not only increase local temperatures through additional heat storage in the paving materials, but also reduce evaporative cooling on the ground surfaces. Therefore, permeable pavements are considered an effective solution for mitigating the thermal discomforts in hot climates. In this study, the thermal behaviours and performances of permeable concrete pavement were investigated with a series of simulation experiments in the laboratory. For comparison purposes, traditional Portland cement concrete (PCC) and Portland cement porous concrete (PCPC), which are commonly used in municipal pavements, were considered for the study. The thermal properties of those materials and their thermal impacts on the surroundings were discussed with specially designed tests. It is verified that the laboratory simulation tests and corresponding analysis methods proposed in the study could be utilised to charac...read more

TL;DR: In this article, the authors describe the materials and cooling mechanisms of different paving materials that will store the heat less on pavements and diminish heat islands in urban and suburban areas, where impervious concrete and asphalt pavements heat up during the day and heat is released into the atmosphere at night.
