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.]]> Thu, 03 Jan 2013 15:13:25 GMT https://rip.trb.org/View/1234496
