<p>Compared with ordinary pavement, SMA pavement structure not only has a good high temperature resistance to rutting and low temperature crack resistance, but also has excellent performance, such as seepage resistance, anti-skid, fatigue and durability, so it is widely used for SMA asphalt pavement and the supervision of the work also gradually standardized. In this paper, through the example of SMA asphalt pavement construction quality supervision of Sui-Yue-Zhong Expressway, the main points of SMA asphalt pavement construction quality control are introduced.</p>

Pavement Construction

The asphalt pavement construction monitoring system presented in this paper covers two main asphalt pavement construction processes: hot mix asphalt (HMA) plant production and the laydown and compaction operation. The main architecture of the monitoring system, the development of the required hardware and the software structure, and the implementation process are presented in this paper. The system is able to perform automatic data collection and data transmission, and can automatically provide feedback to the construction site for real-time asphalt pavement construction quality control. The entire process works automatically without much human intervention and covers the entire project throughout the entire construction period in real time. The monitoring system was successfully implemented in the ZhaoMa Highway construction project in China, where it proved to be effective and reliable. The key asphalt plant production parameters, including asphalt content and aggregate gradation, were improved to a statistically significant level as shown by comparing before and after the monitoring system’s deployment. Statistical analysis between asphalt core density and laydown and compaction monitoring data, collected at 20 locations, indicated that rolling passes were highly correlated with density, whereas finishing rolling temperature and HMA laydown temperature were moderately correlated with density. These results imply that implementation of the monitoring system proposed by this paper could improve asphalt construction procedure quality control and asphalt pavement construction quality.

Compaction Degree

Accurate test dada is the basis of quality control in asphalt pavement construction. Comparative test is an important way to improve test operation level and guarantee the accuracy of test data. To check the condition of the SGC devices and the operator’s skill, comparative test was practiced. The test program and the analysis method to the SGC comparative test data was obtained in accordance with ASTM E691. According to the compaction degree data with SGC compaction at 100 times, two kinds of evaluate methods are compared. The results indicate that robust -statistical-method is more sensitive than ASTM E691-method.

In recent years, as a new type of asphalt mixture, rubber asphalt mixture has a lot of excellent road performance, and is being widely used, but the rubber asphalt quality control measures are still in the exploratory stage. How to control the quality of rubber asphalt pavement, and provide technical support for more and more rubber asphalt pavement construction is particularly important. This article mainly analyzes and summarizes from raw material selection of rubber asphalt mixture, mix proportion design of rubber asphalt mixture and measures of construction quality control, forming a set of construction quality control technology of rubber asphalt pavement

Non-uniformity of the asphalt pavement is one of most important reason for early disease, control of non-uniformity in the production process of asphalt pavement is an important measure to ensure that quality and service life of pavement. Nuclear density gauge (PQI) can be non-destructive, rapid detection of asphalt pavement density. This paper give a research and application on the PQI calibration, testing frequency, the control parameters and evaluation index, and proposes a control method of non-uniformity in asphalt pavement construction with PQI. Asphalt pavement quality control in construction process can use this method. It is important to improve the stability of asphalt pavement quality and reduce the incidence of disease, and also has a certain reference value for establishing the quality control and quality assurance systems.
