CONSTRUCTION OF BASE COURSE

摘要

PROBLEM TO BE SOLVED: To improve the workability by penetrating the slurry-type solidifying material from a surface of a banking so as to solidify the whole of the banking. ;SOLUTION: A banking layer 2 is formed at the same height with a base course 1 to be constructed without performing the soil compaction of the material such as the soil, which is generate in a construction field, or the low-cost material, in which concrete glass is mixed. Continuously, the slurry-type solidifying material 3 having excellent flowing ability such as mortar and concrete is spread over a surface of the banking layer 2 so as to be naturally penetrate through multiple spaces, which exist between soil grains. After the solidifying material 3 is hardened so as to form a base course 1, asphalt and concrete is placed on the base course 1. As a solidifying material 3, the soil generated in a construction field, slurry, or bentonite, which is generated at other construction field, clay, sludge of river, and the mixture of wasted member such as discharged mud from a factory and the consolidifying material such as cement is used at need. With this structure, construction period can be shortened, and while cost is lowered, and while generation of dust can be prevented.;COPYRIGHT: (C)1998,JPO
