| Research Abstract |
The developed heat reflective pavements are constructed from open-graded asphalt concrete in which voids in the upper part of the pavement are filled with a cement mortar containing recycled materials such as oyster shell lime, escallop, coral sand, pottery debris, glass cullet, or roof tile debris. The temperature reduction of the pavement surfaces at an open site was evaluated experimentally by taking measurements in summer. The results show that the maximum surface temperature of the pavements fell by about 10 degrees compared with that of an asphalt concrete pavement.
