Monitoring Method And System Of The Construction Quality Of Asphalt Pavement Of Expressway

In the field of highway construction, because of the construction quality management system has long been the great defects, which makes China’s highway asphalt pavement early damage has not get rid of the fate. After a lot of practice has proved,the current post acceptance testing system can not on asphalt pavement early damageresults improved. In particular, a serious impact on the asphalt pavement qualityproblems of construction quality management system in the present is "false data" problem. Therefore, to establish a set of perfect asphalt pavement construction quality control system and the information management become an urgent task.This paper is to develop a perfect information management system for the ultimate goal,the "white and black" of expressway asphalt pavement construction as the background,establish a quality monitoring system of pavement construction process.Firstly, combined with the previous consultation work of asphalt pavement, a careful reading of construction drawings, according to the actual situation of the project, the preparation of pavement construction quality control and management manual of the project, so as to establish the asphalt pavement construction quality assurance systemand management procedure and information management platform.Then, according to the "Delphi method" to design a form used to collect the opinions of the experts, statistics of 15 experts on the index "the importance of scale" and "evaluation standard" opinions and establish some judgment matrix by the improved AHP method to calculate the index weight value.Finally, indicators of quality at all times and in all countries throughout the measurement method, recommended combining with the expert scoring method and PWL(The allowable limits percentage) to set up the evaluation criterion of the index system, and finally return to the scores of unified standards for general priceof the whole pavement, thus established The scoring system of index in evaluation factor layer. Then, combined with the weight value of index, it can be used to calculate the higher level index score, make to each construction step can make evaluation. At the same time, in order to prevent the emergence of the "false data", it is need to be a validity check for the data of parties in the construction. Finally, to illustrate the process of pavement construction quality assessment by specific construction cited a section, and shows its good effect in actual constructionoperation. To make a solid theoretical foundation for the development of the perfect information management system.
