The Analysis Of Pavement Maintenance Decision On The Basis Of Study On Broken Slab And Crack In Cement Concrete Pavement

Since on the 80's century, highway construction has obtained rapid development on our country. The development has brought the maintenance work to aggravate day by day. It is safeguard for the road providing high speed, unimpeded and comfortable driving for the vehicles to keep road surface service performance fine. Therefore, the maintenance and supervisory work of the road surface to play the very important role.According to the lack of the systemic examination of road surface maintenance management, the present policy-making management of appraisal and the science maintains on our country, this article takes the management decision-making question of the project level surface maintenance as the research object. Basing on researching on the damage of the board crack to the cement concrete road surface and daily maintains to the cement concrete road surface, it carries on the reasonable appraisal and the forecast to the road surface operational performance and the surface maintenance demand analysis, then colligates project technology and the economic knowledge to carry on the decision analysis about maintains. Finally, it unifies the highway maintenance management the present situation in Tongchuan city Shanxi Province, and proposes the method which is put forward in this article, then it has carried on case analysis of the management decision-making about the project level surface maintenance.This article has researched three questions: the research on the damage about the breaks of the board crack in the cement concrete road surface, the demand analysis about surface maintenance, the countermeasure analysis about surface maintenance.The research aspect on the damage about the breaks of the board crack in the cement concrete road surface, takes the investigation about the cement concrete road surface in Tongchuan city Shanxi Province as the basis, unifies the domestic and foreign research results, to conduct the system research on the performance condition, the reason, the service method and the service craft on the damage about the breaks of the board crack.In the surface maintenance demand analysis aspect, basing on the research of the reason and the development tendency on the damage about the breaks of the board crack in the cement concrete road surface, forecasts the influence of each kind of operational performance target about the road surface damages to the road surface reasonably.
