Pavement repair is carried out by thick layer construction for road surface damage that occurred on SHIN-MEISHIN EXPRESSWAY managed by West Nippon Expressway Company. Pavement repair by thick layer construction required long-term traffic control, so it was a problem that large-scale traffic congestion occurred. In order to solve this problem, the text reports the results of formulation study of thick layer construction mixtures aimed at shortening the construction time that enables repair by daily traffic control.
