Evaluation of Mixtures from LTPP SPS-10 Warm Mix Asphalt (WMA) Sections.
AltmetricsView Usage Statistics
The Nevada Department of Transportation (NDOT) commenced a full-scale project in 2016 to extensively evaluate Warm Mix Asphalt (WMA) mixtures that would likely be used in the State in the future. This was accomplished by participating in the Specific Pavement Study (SPS) experiment, which was developed under the Long-Term Pavement Performance (LTPP) program and Federal Highway Administration (FHWA) to evaluate the short- and long-term field performance of WMA relative to hot mix asphalt (HMA) mixtures. This report is a summary of the laboratory evaluation completed by University of Nevada, Reno (UNR) to characterize the mixtures placed on the LTPP SPS-10 Warm Mix Asphalt Study conducted in Washoe Valley, NV under NDOT contract 3598. Aiming to investigate both the laboratory measured properties and field performance of multiple WMA technologies compared to respective HMA counterparts with specific focus on short and long-term performance.
