Pavement Preventive Maintenance Decision-making in the Period of Road Design

In the design phase of highway engineering introduced the theory of total life cycle cost analysis, choose reasonable pavement structure scheme and formulate corresponding preventive maintenance plan. Through comparing construction cost and maintenance cost of the pavement structure scheme can get the best design scheme of economical efficiency, at the same time, reasonable preventive maintenance plan can timely repair of disease at the dawn of pavement diseases, generating the best cost effectiveness of the design. According to the design of pavement structure scheme in the existing common disease occurring in the process of road use to formulate the corresponding maintenance scheme, based on theory of hierarchical analysis, studying the preventive maintenance of scheme design stage.
