Abstract: 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.

Abstract: 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.
