A STATISTICAL ANALYSIS OF THE TENSILE STRENGTH OF BITUMINOUS MIXTURES

District 12 (Houston, Texas) has sought to evaluate and reduce the potential for stripping or water sensitivity of bituminous mixtures. Using Test Method Tex-531-C, "Prediction of Moisture-Induced Damage to Bituminous Paving Mixtures Using Molded Specimens," the District tested 312 samples in 1988 and 1989. Liquid anti-strip chemicals were added to most of these samples. Statistical analysis of the test results for tensile strength ratio as well as indirect tensile strength indicate over 80% of the samples which passed minimum strength ratio have a minimum conditioned tensile strength greater than 60 psi.
