Comparative study of flexural strength of in-service concrete pavements

Abstract

One of the key developments required to characterize and improve the performance of (PCC) pavements is a better understanding of its in situ properties. Of great importance is the accurate estimation of in situ concrete strength, because it has a major impact on concrete performance. Damage identification of concrete structure has become a matter of primary importance in quality assessment and load capacity rating of the civil infrastructure, as well as in the planning of a maintenance schedule. There are currently many methods used to estimate in situ strength, each providing unique benefits. This investigation examined an experimental study of compressive strength and modulus of elasticity of in-service concrete pavement. The Compression test is conducted to determine the compressive strength further which is used in finding the flexural strength. The flexural strength is further used for calculation of life expectancy of he pavement.
