PROBLEM TO BE SOLVED: To provide aggregate for pavement, which can alleviate a heat island phenomenon to the possible extent, the heat island phenomenon being caused by many factors including heating of asphalt or concrete pavement on a road surface by solar heat, and to provide a road pavement method. SOLUTION: The aggregate for pavement is formed by preparing a ceramic containing feldspar, clay, pottery stones, and a heat insulating pigment (0.1 to 1.0 wt%), and bonding vacuum spherical ceramic powder having a particle size of 40 to 100μm onto the periphery of the ceramic by burning. The road pavement method is implemented by using the aggregate. COPYRIGHT: (C)2006,JPO&NCIPI
