| Outline of Final Research Achievements |
The developed heat-blocking pavements are constructed from open-graded asphalt concrete in which voids in the upper part of the pavement are filled with a mortar containing recycled materials as a fine aggregate. The recycled materials such as crushed oyster shell, roof tile debris, pottery debris, glass cullet, crushed escallop and coral sand were prepared for filling mortars in this study. The temperature reduction of the pavement surfaces was evaluated experimentally by the lamp irradiation test of the specimens. The results show that the maximum surface temperature of the pavements fell over 10°C compared with that of an asphalt concrete pavement.
