<p>PROBLEM TO BE SOLVED: To provide an elastic paving material capable of suppressing the increase of a surface temperature thereof even in a hot season such as summer.SOLUTION: An elastic pavement material 20 is manufactured by binding rubber chips 10 for elastic pavement formed by foam rubber containing heat shielding pigment. Foamed holes 11 for the rubber chips 10 for elastic pavement are isolated cells. The diameter of the foamed hole 11 (isolated cell) is preferably 20-200μm. The expansion ratio of the rubber chips 10 for elastic pavement is preferably 1.1-3 times. Thus, the elastic pavement material 20 can be made to have a small bulk density and be less apt to increase surface temperature thereof even in a hot season such as summer.</p> |
