Quieter, Smoother, More Durable Pavement Surfaces

Results will extend pavement service and maximize system performance including key properties of smoothness, noise, and durability. Better mix designs for noise and durability of (i) current Caltrans mixes and (ii) potentially new mixes. Meets commitment to Caltrans Quiet Pavement Pilot Project long-term study (>5 years) required by the FHWA. Comparisons will be made with other research (e.g., Danish Road Institute, National Center for Asphalt Technology), other mixes, and improved California mix designs. Field studies include continuing to monitor noise, pavement smoothness, condition, and other properties. New sections established under the Pavement Preservation Task Group (PPTG) will be monitored for 5 year minimum per Federal Highway Administration (FHWA) requirement. Laboratory study of mix designs for better noise reduction and durability over time. Continuing to build data base and document field measurements and laboratory tests.
