Project Details

Title:Development of a Guideline for Selection of Tack Coats in South Dakota
Principal Investigators:Rouzbeh Ghabchi
University:South Dakota State University
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-522
RH Display ID:153395
Keywords:delamination, failure, fatigue cracking, guidelines, moisture content, pavement distress, rutting, tack coats


The proposed study will evaluate the effectiveness of tack coats commonly used by the South Dakota Department of Transportation (SDDOT) with respect to their types and application rates, pavement surface conditions, moisture-damage and temperature. Interlayer shear strength of tack coat determined by using a Louisiana Interlayer Shear Strength Tester (LISST), developed by Mohammad et al. (2012) will be used for evaluation of the tack coats. Also, laboratory-compacted samples and a number of field cores (based on their availability) collected from selected construction sites in South Dakota will be tested to evaluate the tack coat performance.
