Abstract: This report presents the results of laboratory work on flexural and compressive strength, free shrinkage, coefficient of thermal expansion, and elastic modulus performed on six concrete mixes. The six concrete mixes are typical of those used, or have been considered for use, for the Caltrans Long Life Pavement Rehabilitation Strategies for rigid pavements (LLPRS-Rigid). The work presented in this report was completed as part of Goal 4 of the Partnered Pavement Research Program Strategic Plan, and completes the following objectives of the test plan for that research goal: - - - Evaluation of, and development of recommendations for test methods for strength gain, ultimate strength and stiffness, thermal expansion, and shrinkage. - Development of laboratory data regarding the properties of various high earlystrength concrete mixes, and comparison with a typical Type I/II mix. - Development of laboratory data regarding the effects of important mix design and construction variables on mechanical properties.
