Special Polymer Modified Asphalt Cement. Final Report
This study evaluated and compared the effectiveness of polymer-modified asphalt mixes in improving the performance of the roadway in relation to rutting and cracking as compared to the authors' standard mixes without modified binders. Results from this study indicate that cracking is reduced when polymer-modified asphalts are used. However this study did not make clear when a polymer is needed or whether it was cost-effective. With the introduction of SHRP performance graded asphalt binder, CDOT will be able to better evaluate the effects of both temperature and traffic and how they relate to the performance gradings. The addition of various polymers used in this study did not enhance the rut resistance potential of the mix, however the addition of the polymer did reduce the amount of transverse and longitudinal cracking to some extent.
