Dynamic Control Quality System Of Asphalt Pavement Construction

Construction quality control of asphalt pavement caused by the negative is an important reason for the destruction. Asphalt pavement construction quality control is a dynamic process that needs to run through the construction of asphalt concrete surface always, on the whole process of control, according to the deviation found in the production of timely adjustments to the production under control and ensure the quality of road works. Therefore, the dynamic control of the construction of asphalt pavement into the "statistical process control" areas of asphalt pavement will be considered as a product, the scientific use of statistical knowledge of the construction process of asphalt pavement, "real-time monitoring", has an important practical value.First of all, This paper introduces the definition of structural reliability and computational methods; a detailed analysis of structural reliability in the construction process of asphalt pavement structure of the meaning of quality control; discusses the use of China's construction of asphalt pavement and road surfaces, structural reliability parameters of Contact; further study the structural reliability and quality of the relationship between the dynamic control.In this paper, the application of the principles of statistical analysis methods, through the introduction of conventional control tools such as control charts, quality control indicators to establish the mean and variability of process control methods. The key to control technology, control charts to determine the criteria and quality improvement research, quality control charts for dynamic control of the application of further study. In introducing the control chart based on the further introduction of the histogram, the time chart in terms of quality control in the use of dynamic analysis. And then affect the quality of asphalt pavement construction of the key factors, such as proportion, materials, construction techniques and dynamic quality management to conduct in-depth analysis. Finally, the asphalt pavement construction quality management system for dynamic control of the development and functional analysis. Analysis of dynamic control of quality indicators chosen by the guiding ideology and principles, the initial selection of indicators of construction control. To the principle of easy-to-use to support quality control for the purpose of using Visual Basic as a development platform to ODBC database technology on the operation of Access to C / S for the software architecture, developed the "asphalt pavement construction quality control system dynamics." The system can carry out random sampling basis, and provides the data collected into preservation, calculation and analysis and judgments, such as multi-function print out the chart. System interface is very friendly, the features at a glance, and with the help of a powerful system to meet the dynamic operational control of the road construction, real-time, intelligent.
