Abstract:

A laboratory evaluation of antistripping additives is presented. The three additives included one lime additive added to the aggregates and two liquid additives mixed with the asphalt cements. Each additive was evaluated at various levels of concentration. Control mixtures with no additives were also evaluated. The laboratory evaluation program consisted of measuring the unconditioned resilient modulus at various temperatures and the moisture-conditioned resilient modulus and tensile strength. The ratios of the unconditioned to the conditioned values were also used in the evaluation. On the basis of the results of the laboratory evaluation program, lime reduces the stripping potential of asphalt concrete mixtures. The liquid additives did not provide any significant improvement in the measured strength parameters (resilient modulus and tensile strength) of asphalt concrete mixtures. Therefore, the liquid additives have not proven to be effective antistripping additives.
