SMA Asphalt Pavement Quality Control Technology

With China’s rapid economic development in recent years, rapid highway development momentum across the country, the total mileage of expressways open to traffic in China is ranked second in the world, is expected to reach100,000km by2020, but the attendant problems asphalt pavement early damage is serious, affecting the ride comfort, has drawn increasing attention of the industry. The research shows that the quality of asphalt pavement construction process nonuniformity early destruction of important factors, combined with the construction of the concrete situation therefore, strengthen the quality control of asphalt pavement construction keep the construction of dynamic analysis is to ensure the life of the asphalt pavement and an effective way to improve the quality of the road surface.Are many factors that affect the quality of the asphalt pavement construction, where the deviation of a factor likely to affect the final quality of the asphalt pavement. Screened so many factors impact the quality of asphalt pavement larger indicators focus on analysis and dynamic monitoring and indicators, so as to effectively guarantee the stability and uniformity of asphalt concrete.Bin Germany highway projects relying Research and dynamic analysis of the main indicators of the asphalt pavement, combined with a lot of trial and testing data, analysis of the level of variation, the distribution of the impact of the law on the quality of the road surface, proposed decreases in the construction process in specific measures of variability, and ultimately achieve the purpose of controlling the quality of asphalt concrete pavement. The main indicators of the asphalt pavement in this article is divided into two categories:one is the reaction the asphalt mixture comprehensive performance indicators, namely asphalt penetration, softening point, ductility, following the distribution of aggregates, coarse aggregates containing Mud amount of needle flaky particles content, asphalt content, asphalt mixture gradation; class is the reaction of the ultimate nature of the asphalt pavement, transport that the degree of compaction, flatness, pavement thickness, construction temperature asphalt mixture, asphalt mixing The mixing of the material. Above the main indicators ultimately played a significant role on the Marina De highway construction projects quality control.
