Design, Construction, and Performance of Sulfur-Modified Mix in the WMA Certification Program at the NCAT Pavement Test Track

This report presents the results of a test performed by the National Center for Asphalt Technology (NCAT) to compare the performance of Shell Thiopave, a sulfur-modified warm-mix asphalt (WMA), with a conventional hot-mix asphalt. The performance of the mixes were tested at the NCAT Pavement Test Track in May of 2010. Laboratory and performance testing included: rutting, dynamic modulus testing, tensile strength ratio, Hamburg Wheel-Tracking, boiling water testing, temperature analysis, bond strength, roughness, durability, and cracking. Based on the tests NCAT recommends the acceptance of the WMA Shell Thiopave.
