| Asphalt pavement has a smooth ride, good mechanical strength, easy constructionand low noise characteristics of the asphalt pavement is used in large-scale highwayconstruction, along with the development of the last century, the construction ofhighway asphalt pavement into the homes stage, howaccording to the type of asphaltpavement diseases choose the best conservation programs to reduce the quantitiesthereby reducing maintenance costs was placed in front of the majority of roadresearchers.In this paper, on the basis of access to a large number of documents andinformation, the main diseases of origin and type of highway asphalt pavement to do adetailed analysis.From the the conservation technical point of view, for a variety of diseases, fromthe technical characteristics, process, principles, technical requirements, process andconstruction requirements detailed analysis of the modified emulsified asphaltmicro-surfacing construction technology, fog seal construction technology, in situ heatrenewable technologies, asphalt pavement transformation of four asphalt pavementmaintenance technology optimized design technology and engineering example,through the analysis of the project’s comprehensive road performance and trafficinvestigation and analysis, and ultimately determine the appropriate conservationtechniques.Expressway Asphalt Pavement Performance Evaluation to improve the use ofperformance evaluation method, introduced in the evaluation of asphalt pavementrutting depth status evaluation, in view of the weighted arithmetic average method todetermine the comprehensive evaluation of the asphalt pavement the indicators makeindicators "neglected" feature, we use weighted geometric average method to determinethe asphalt pavement evaluation indicators PQI. Instance of the use of highway asphaltpavement performance evaluation model was tested to prove the feasibility of the modelon the asphalt pavement maintenance and performance evaluation.Through the use of highway asphalt pavement performance evaluation, analysis ofthe evaluation of the the conservation quality assessment and maintenance costs, thehighway asphalt pavement maintenance management decision-making model, and0-1 linear programming decision-making optimization methods for engineering instanceconservation and management analysis of the decision-making.Maintenance Management System to promote the development of road maintenannce management, maintenance funds, maintenance and conservation of the marketbaking. |
