Jiyan Highway Asphalt Mixture Construction Quality Control

At any time of the rapid development of our country highway, asphalt pavement construction in the existence of the problem is also becoming increasingly prominent. Mainly reflected in three aspects, first, the quality of raw materials, regulatory requirements often can not; second, asphalt mixture design could not fully take into account the actual environment, resulting in the asphalt mixture design can not meet the performance requirements by road; third, asphalt mixtures of the mixing, transportation, paver, roller, such as poor quality control. This caused the early damage of asphalt pavement.In this paper, the control target from the technology, production process control, construction management to control the three aspects, in-depth analysis of the asphalt, aggregate, filler and the asphalt mixture production, storage, transportation, use of the four had said should be the focus of attention problem , and the corresponding solution. jiyan for the project to rely on high-speed on asphalt mixture than with the aim of the design, production design mix optimized inspection and verification. Finally, construction of asphalt mixture problem that often appear in isolation, lack of smoothness, as well as inadequate or excessive degree of compaction as the starting point, these three questions, respectively, conducted a study that proposed ways to improve the problem, as well as comprehensive evaluation of the quality standards .
