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.

As an important part of the asphalt pavement construction, quality control is directly related to the life of road. In view of the non-uniformity issues in asphalt mixture production and construction processes, depending on the segregation standards in asphalt pavement testing, the universal volumetric chart is used to control the asphalt mixture’s volume indexes in this paper. And a PQI (pavement quality indicator) is used to make a non-destructive inspection of the pavement density. Finally, the controlling and monitoring system from asphalt mixture production to asphalt pavement construction and applying software with asphalt pavement construction quality control and quality assurance in the platform of MATLAB are developed in this paper. According to the field application, the system and software developed in this paper could be well used in the asphalt pavement construction quality control.

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.

Hot Mixed Asphalt

As the stability of quality of hot mixed asphalt mixture (including gradation, asphalt aggregate ratio, temperature, etc) is the premise of good pavement performance of asphalt pavement, it is regarded the key of ensuring service life and pavement performance of road to ensure the quality of hot mixed asphalt mixture. This research is oriented at developing real-time quality control & monitoring system of asphalt mixture further on the basis of the established quality control system of mixing plant. The functions and operating principles of the system are introduced in this article.

Base on the process of asphalt pavement construction, analyse the influence factors of energy-saving and emission-reduction in asphalt pavement construction. Research shows thatduring the asphalt pavement construction process, all kinds of construction machinery are the main source of energy consumption and emissions; Asphalt mixture also emission part of gases itself, which closely related with the heating temperature of the mixture.
