Parametric Study of The Parameters Affecting Concrete Pavement Thickness

Beton Kaplama Kalınlığına Etki Eden Parametrelerin Parametrik Olarak İncelenmesi

Abstract

Concrete pavements are the superstructure elements that can serve for a long time withoutdeterioration. Concrete pavements are using intensively for interstate highways where heavy traffic volume ishigh, parking facilities, airfields and industrial facilities. One of the most important features of concrete pavements,which are widely used in interstate roads in America, is more environmentally friendly compared to flexiblesuperstructures. This increases the need for concrete pavements in our time when sustainability is important.Because of the complex concrete properties and soil properties, the concrete pavement design is complex thanexpected. Due to the complexity of the designs, they were previously designed based on experiences. Subsequently,design methods with both mechanical and experimental infrastructure have been developed thanks to mechanicalmethods. Among these design methods, PCA 1984 and AASHTO 1993 are the most widely used for concretepavement design. Both the PCA 1984 and the AASHTO 1993 design method are used concrete properties, subgradereaction, and traffic characteristics as input parameters. In this study, three main parameters affecting concretepavement thickness (concrete properties, soil reaction and traffic) were examined according to AASHTO and PCAmethods. By this way, the correlation between pavement thickness and these parameters is shown. Another resultobtained from this study is which parameters are more sensitive to concrete pavement thickness.
