Method and system for controlling effective compaction time in asphalt mixture mixing construction process

Abstract

The invention discloses a warm mix asphalt mixture construction process effective compaction time control method and a warm mix asphalt mixture construction process effective compaction time control system, which are applied to the technical field of traffic construction. Fuzzy variables and a fuzzy set of the fuzzy variables are determined, and the fuzzy variables are divided; determining a discourse domain table according to the division result of the fuzzy variables and the corresponding relation of the fuzzy sets; constructing fuzzy inference rules, and obtaining different fuzzy relation equations according to different fuzzy inference rules; and obtaining an output value according to the fuzzy vector value in combination with different fuzzy relation equations, and determining an accurate value through a defuzzification method. According to the fuzzy analysis method for the effective compaction time of the asphalt mixture, the requirement of surface layer construction can be basically met, and especially when the air temperature is lower than 20 DEG C or other environment conditions are severe, prediction of the effective compaction time of the asphalt mixture has important significance. And when the environmental condition is better and the surface layer is thicker, the compaction time of the asphalt mixture can meet the requirement of normal rolling work.

Description

technical field [0001] The invention relates to the technical field of traffic construction, and more particularly to a method and system for controlling the effective compaction time during the construction of warm mix asphalt. Background technique [0002] With the development of the national economy, the rapid growth of traffic volume, coupled with large-scale vehicles, serious overloading, and canalized traffic, etc., make the early damage to the asphalt pavement under construction serious. Numerous studies have shown that the early damage of asphalt pavement is directly related to the degree of compaction of the pavement. If there are any quality defects in the rolling, it will definitely affect the performance of the road surface. Good asphalt pavement quality is also reflected by rolling. High-quality rolling can improve the bearing capacity of the pavement, increase the density, reduce the porosity, and increase the durability of the pavement. Performance has a big...

Problems solved by technology

According to the survey, the asphalt pavement of many newly-built expressways has early damage shortly after it is opened to traffic. A large part of the reason is that the temperature and the required rolling time for pavement forming are not scientifically controlled.
