On the Grading Range of MS-6 Aggregate Grains and the Optimum Range of Asphalt Dosage
This article deals with the reasons why another ruts are easily produced while filling the ruts about the 20mm deep with two-layer slurry mixture,and the necessity to develop MS-6 Course slurry mixture of the aggregate grains of maximum diameter of 20mm.It is found that,different from hot-mix-hot-laid technology,slurry technology requires not only the aggregate gradation enabling the slurry mixture to get to optimum workability,but also the aggregate gradation enabling the micro-surfacing to reach to maximum density.This writer sums up and puts forward the theory of optimum workability grading curve,the theory of aggregate grains arrangement,and the theory of anti-particle interference; on the basis of the theory of maximum density grading curve,the writer specifies the grading range of MS-6 aggregate grains and the optimum range of asphalt dosage.Synopsis:Haiyou Wang ( 1964-),Male,Dr.reading,senior engineer,has long been engaged in road materials research.
