This paper presents a summary of five strength tests currently being used to evaluate the load-carrying capability of concrete pavements. The five tests were those for compression, flexure, splitting tensile, ring tensile, and shearing. The strength relationships between these tests reported by 13 sources are presented. A combined analysis was performed on test results from 3640 concrete samples and some relationships were developed. In view of the numerous factors influencing the relationships of the strengths of concrete, it is not surprising that no simple exact relation is applicable. However, these correlations are felt to be representative in lieu of specific testing for concrete pavement design and evaluation.
