Evaluation of bond strength between hot mix asphalt and stone mastic asphalt surfacing layer
Poor bonding between asphalt layers cause many distresses, and the most typical problem is the slippage failure. This failure usually occurs when there are exists insufficient bond between the interfaces of the two layers in contact. Therefore, sufficient tack coat is needed to provide greater bondi...
