CONSTRUCTION METHOD FOR COMPOUND DISPERSION TYPE SURFACE TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a construction method for compound layer dispersion type surface treatment allowing early freedom of traffic and having less dispersion of aggregate and also a pavement body excellent in durability and stability built by such surface treating construction method. SOLUTION: A plurality of surface treatment layers are built on the road by repeating at least two times the work of dispersing binding material 2a, 2b and then aggregate 3a, 3b thereover. A construction method for compound layer dispersion type surface treatment of the aggregate 3a used on at least the lowest layer being a precoat aggregate and the aggregate 3b used on at least the utmost top layer being a non-precoat aggregate is provided together with a pavement body built by such construction method of compound layer dispersion type surface treatment.
