WebBonded trackless tack samples were resistant to fatigue cracking and cold temperature delamination. Bond strengths from field samples were considerably lower (15–95 psi) than for lab-molded samples (100–200 psi) and varied among different overlay projects. Webtrackless tacks in the Texas Department of Transportation. Also, a damage model for tackiness is needed to characterize the fracture properties of the tacks. The main objectives of this study were to 1) investigate the material characterization of trackless tacks, 2) evaluate the bonding potential of trackless tacks, and 3) develop a predictive
WebThe hot-applied polymer modified tack coat is heated until it is liquid and sprayable and, then, sprayed on the pavement to create the thick layer. Typically this tack coat is applied at the rate of 0.04 to 0.8 gals/yd 2 for a conventional HMA overlay, or 0.09 to 0.18 gals/yd 2 for a Bonded Friction Course.
