Heat lump in different pavement layer using water as a heat collector
Asphalt pavements subject to solar radiation can reach high temperature causing not only environmental problems such as heat island effect on cities but also structural damage due to rutting or hardening of road.

| Summary: | Asphalt pavements subject to solar radiation can reach high temperature causing not only environmental problems such as heat island effect on cities but also structural damage due to rutting or hardening of road. The main aim of this research is to determine the maximum heat area in pavement where the scope of study consists of field experiment under real atmospheric condition and laboratory testing. The rise in temperature of water solvent flowing through the conduction of steel pipe was used as indicator of the efficiency of heat capture. The data from field experiment had been collected using data logger and the reading of temperature was recorded every 5 min for 24 h starting from 12-12 am the next day for 3 days to get the average temperature reading of water solvent in steel pipes. Steel pipe with water solvent at depth of 50 mm has the maximum temperature of heat area in pavement with highest thermal storage and can withst and the highest vehicle loading applied on it. � Medwell Journals, 2017. |
