NETC 04-1 (Phase 2) NETC 04-3 NETC 04-4 NETC PROJECT 04-1 (Phase 2) PROJECT TITLE: Recycling Asphalt Pavements Containing Modified Binders - Phase 2 PRINCIPAL INVESTIGATOR(S): James Mahoney, University of Connecticut PI Email: james.mahoney@uconn.edu STATUS: Active ANTICIPATED COMPLETION: 9/30/2009 PROJECT OBJECTIVES: Phase 2: The objectives of the second Phase of this project will attempt to address incompatibilities that may arise when RAP is used in a new HMA pavement that contains a virgin modified asphalt binder. This Phase of the project will also provide guidance as to the proper amount of RAP that can be added to the HMA without causing problems. In addition, the interaction of polyphosphoric acid modified virgin asphalts and the aggregates in the RAP will also be tested to determine if there is a negative impact on the HMA mixes performance. NETC PROJECT 04-3 PROJECT TITLE: Estimating the Magnitude of Peak Flows for Steep Gradient Streams in New England PRINCIPAL INVESTIGATOR(S): Jennifer Jacobs, PI, Thomas Ballestero, Co-PI, University of New Hampshire, and Richard Vogel, Co-PI, Tufts University PI Email: jennifer.jacobs@unh.edu STATUS: Agreement extension pending ANTICIPATED COMPLETION: To be determined PROJECT OBJECTIVES: The main objective of this research is to develop a set of regional regression relationships to predict flood flows for steep slope watersheds from basin characteristics. The regression relationships will be developed using standard USGS regional hydrologic methods. We propose to identify target watersheds in the New England region and to develop a database of physical basin parameters and historical streamflow necessary for the statistical analysis. Regression analyses will be conducted to identify explanatory variables and to develop regression relationships for average daily flow and 2-, 10-, 25-, 50-, and 100-year peak flow recurrence interval events. As appropriate, the New England states will be divided into subregions. NETC PROJECT 04-4 PROJECT TITLE: Determining the Effective PG Grade of Binder in RAP Mixes PRINCIPAL INVESTIGATOR(S): Jo Sias Daniel, University of New Hampshire and Walaa Mogawer, University of Massachusetts Dartmouth PI Email: jo.daniel@unh.edu STATUS: Active ANTICIPATED COMPLETION: 9/30/2009 PROJECT OBJECTIVES: The main objective of this research is to develop a method to determine or estimate the binder grade in mixtures designed with RAP from the properties of the mixture itself.
