Title: Quality control for aggregate handling in asphalt pavement construction
Abstract: The traditional aggregate handling method has the defects of poor quality in processing and low rate of qualified aggregate in highway construction in China.This paper investigated the sieve sizes for aggregate handling and the variation of aggregate gradation from more than 30 sections of the asphalt pavement construction.And it found and used a set of standardized sieve sizes for aggregate handling on a large scale processing.It is pointed out that the relationship between the sieve sizes for aggregate handling and the standard sieve sizes should be controlled.The relationship between the aggregate specifications and the sieve sizes for aggregate handling and the relationship between the sort of mix and the aggregate specifications are put forward.The applications result showed that the qualified rate of the aggregate is 100%,and the variation of aggregate gradation is less than 2.7%.6 tabs,10 refs.
