RATIONALIZED CONSTRUCTION WORK CONTROL STANDARD FOR ASPHALT FACING IN CONSIDERATION OF ALL-YEAR-ROUND CONSTRUCTION

Abstract

In Japan, technical standard for asphalt facing work has not been established yet. Therefore, precedent construction work control standards for asphalt facing were mainly based on empirical knowledge.
In this paper, a unique construction work control standard for asphalt facing work was illustrated by clarifying the reasons obtained through laboratory tests and field trials. In order to achieve all-year-round construction and rationalized standardization, some new trials were executed including standardization on temperature of asphalt mixture mainly focused on the last compaction work, variable standardization on asphalt content according to meteorological condition and construction area, etc.
