Influence of tack coat rate on the properties of paving ...

2014-3-1  According to AASHTO M 288-05 (2001), the specified rate of asphalt tack coat application should satisfy the asphalt retention capacity of the paving geosynthetic, and be able to bond the paving fabric and overlay to the old pavement. ASTM D 6140 (2005) provides a test method to estimate the asphalt retention capacity of paving geosynthetics.

2017-9-1  Tack coat rate. The asphalt sprayed on the top of the lower layer can fill voids of underneath pavement and increase contact area, and in consequence, increase the adhesion of the interlayer. In comparison, if the tack coat was placed too heavy, a slip plane can be introduced at the interlayer and decrease the adhesion and interlocking resistance.
