Evaluation of bond strength between hot mix asphalt surfacing layers

This paper investigates the effect of tack coat types, application rates, and layer thickness on HMA interface shear strength. The performance of tack coat materials on AC 10 was evaluated. Three emulsions were selected as tack coat material which are RS-1K, RS-2K, and RS-2KL.These tack coat materia...
