PROBLEM TO BE SOLVED: To provide high fluidal performance for a short time at repairing pavement surrounding guide light part by constructing one or more layers in which aggregate and cement asphalt mortar are charged in order and solidified in an excavated part. SOLUTION: Inside an excavated part of pavement 2 which is formed by cutting off the surrounding light part, a tack coat layer is laid and aggregate 6 is laid thereon, and lightly pressed by rolling. The cavities of the aggregate is filled with CA mortar 7, aggregate 8 of smaller maximum grain size than the former is levelingly laid thereon, lightly pressed by rolling so as to be flush with the surface of the existing pavement 2, and then CA mortar 7 is charged and solidified so as to form a light installation base 9. A light installation space part 10 is formed in the base 9 so as to arrange a light pedestal therein, a necessary wiring cord 12 is connected to it, and the space is filled with epoxy resin mortar 13 and fixed. Further it is filled with aggregate 6 and CA mortar 7 and solidified, the upper face of the base 9 is cut and removed, and heated asphalt mixture is paved to form a surface layer 14. |
