| Early destruction of the asphalt pavement is the most serious problem of highway asphaltpavement in China, one of the main reasons for which is the lower level of constructionquality management and control. The current specification is lack of quality control system tocontrol the quality of the construction and evaluation of asphalt pavement. Therefore, in orderto reduce the early destruction of the asphalt pavement, improve the service life of the asphaltpavement, there is an urgent need to address the asphalt pavement construction quality controlissues, the establishment of effective asphalt pavement construction quality control system.Firstly, gradation variability analysis of raw materials and mix as well as the roadtransport and paving process and temperature segregation begin from Asphalt Pavementproduction process, combined with advanced non-destructive testing means and methods inasphalt pavement construction process key indicator of the quality control of raw materialsand asphalt mixture;Secondly, build a PSR model Pavement Construction Quality Control System, acomprehensive analysis of the actual situation of the asphalt pavement construction, so theintuitive evaluation throughout the construction process, the formation of the key indicators ofconstruction quality control system content simple, and has a strong the operability can becontinuity.Thirdly, the use of improved AHP method, according to the weight of the determiningstep, gradually calculated the value of the weight of the asphalt pavement construction qualitycontrol system in key indicators. For the purpose of real-time monitoring of road construction,and given control of key indicators, in accordance with the combination of quantitative andqualitative evaluation criteria for each index construction quality control system; givencontrol range for each indicator different score, the assignment of different ranges, settinglimit values prohibit construction, real-time detection and effective control of the indicators ofpre-construction or construction process, to ensure maximum quality of road construction. Finally, the asphalt pavement construction quality control system based on key indicatorsused in the physical works to limit construction and construction mode, the application andverification is carried out to examine the suitability and applicability, and received goodresults, which verifying the validity and reliability of the system. |
