This study assessed the effectiveness of latex polymer anti-stripping treatment by inspecting and evaluating the condition of pavements constructed in Oregon from 1997-2001. Ten hot mix asphalt concrete paving projects were identified throughout the state. Five of the projects used hydrated lime as an anti-stripping additive, and five used latex polymer (UP-5000) as an anti-stripping additive. Each paving project that used UP-5000 as an antistripping additive was compared to a paving project that used hydrated lime as an additive. Both sites being compared shared similar aggregate sources. Condition surveys were conducted on all of the sites, and in-service cores were taken from each project. The cores were tested using the AASHTO T 283 test method to determine the Tensile Strength Ratio (TSR). The TSR and condition ratings were used to assess the effectiveness of the UP-5000 compared to hydrated lime. Based on the condition surveys, and the TSR testing, the UP-5000 was shown to be comparable to hydrated lime in preventing moisture induced distress in hot mix asphalt pavements in Oregon.
