PROBLEM TO BE SOLVED: To prevent the worsening of visibility of a colored part of a pavement and to prevent the worsening of sight of the pavement with the lapse of time by mixing a glass powder in a colored pavement body containing a petroleum resin based binder material, a pigment and an aggregate. SOLUTION: This colored pavement body contains the petroleum resin based binder material, the pigment and the aggregate containing the glass powder. As the aggregate, a colored aggregate is preferably used. The glass powder is preferably one having <=600μm particle diameter. As the petroleum resin based binder material, for example a combined binder (thermosetting decolored binder) prepared by using a usual decolored binder (a petroleum resin) as a base binder and mixing about 40wt.% flexible epoxy resin for the purpose of the improvement of durability or the like can be used. To pave the colored pavement using the colored pavement body, the aggregate containing the glass powder, the petroleum resin based binder material and the pigment are mixed and the mixture is placed and tamped. The glass powder is preferably contained by 9-60wt.% per the whole mixture. |
