Research On Method Of Payment In Accordance With The Quality Of Asphalt Pavement Based On Key Indicators

At present, China's early damage to asphalt pavement is widespread, although there are many reasons, but the asphalt pavement construction quality management techniques and payment methods of deficiency is undoubtedly the most important reason. Asphalt pavement project owners in quality management and financial investment, but often unrewarding, the contractor of asphalt pavement as the subject of quality management and quality objectives can not be consistent with the owner, take the initiative to enhance and improve the quality of a serious shortage. The reason, main is to present the asphalt pavement construction quality assessment system and payment, the current system of quality assessment of asphalt pavement construction quality assessment is unqualified or unqualified, qualified to accept and pay the owner, unqualified refuse to accept. This way not according to the actual quality of the asphalt pavement are unable to pay, thus arouses the construction units and improve the construction quality of enthusiasm. In this case, the construction unit can reduce cost in the premise that engineering quality inspection, to seek more interests, it is not difficult to guarantee to improve even the quality of construction projects. Therefore, we need to use for reference foreign successful experience, introducing the concept of coefficient, pay according to the actual construction of asphalt pavement quality level, calculate the corresponding pay coefficient, the construction quality and value of the project will be contacted directly, poor quality of the original contract price in the future based on the part of the excessive deduction for expenses of compensation for maintenance, Good quality in the contract on the basis of the price paid to encourage more active part, to improve the quality of construction contractors to extend the service life.In this paper, the existing asphalt pavement construction specifications and quality inspection and assessment of standards-based, comprehensive domestic and international existing asphalt pavement construction quality control of evaluation indexes of research results, field investigation, expert interview, summed up the quality of asphalt pavement construction of factors, summarized in this basis, the construction of asphalt pavement quality evaluation of key indicators, and the importance of the various indicators according to different weight distribution, and then build a complete asphalt pavement quality evaluation system. Finally, the asphalt pavement quality evaluation system for the construction of asphalt pavement quality level of quantitative assessment, by payment factor.In order to verify the reliability of payment methods with quality, one section gives the example of the calculation and evaluation of data for specific recommendations is given.
