An effective bond coat for longer pavement life

Tack coat treatments are routinely used to promote a satisfactory bond between an existing pavement surface and new asphaltic concrete overlay. A satisfactory bond is essential to maximise the structural design performance of the overall pavement. In thin layers the tack or bond coat is critical in resisting high shear forces and preventing delamination failures. This paper reviews the local development of a bond coat emulsion with improved bond strength and negligible construction tyre pickup. It also describes a novel laboratory sample preparation method utilising a shear box compactor as well as laboratory bond strength testing for various tack coat conditions. Field trial observations are reported and practical field applications are described. (a) For the covering record of the conference, please refer to ITRD no. E218387.
