Survey and Evaluation of Damage to Cement Concrete Pavement

摘要

The size and technical measures of concrete pavement maintenance depend on the damage to the old pavement and the economic strength, and problems about the survey and evaluation methods of damage to old cement pavement have not been well solved yet. This paper, on the basis of years' engineering practice and adopting random theory as well as fuzzy math principles, puts forward a set of applicable, highly reliable survey and evaluation approaches. And compared with the methods in PCI pavement composite indexes and China's design norms for cement concrete pavement (JTJ012-94), those put forward in this paper prove to be workable and can be disseminated and applied in practice.
