A -- EFFECTS OF HIGHER STRENGTH AND ASSOCIATED CONCRETE PROPERTIES ON PAVEMENT PERFORMANCE. SOL RFP No. DTFH61-95-R-00108 DUE 041795 POC Contact Behrooz Behpoory, HCP-30, (202) 366-4224 A - The objectives of this study are to 1) Determine the properties of portland cement concrete (PCC) of higher strength found in certain in-service pavements which resulted in good long term performance; in particular freedom from distress near joints and free edges. 2) Identify test methods to measure (quantify) these properties. Also, determine the materials characteristics of the concrete which are responsible for the levels of these properties found in the concrete. 3) Develop prototype mix designs and specifications for concrete for use in pavements that would posess these properties while still meeting the needs of current specifications and construction requirements. To expedite request, please furnish two self-addressed gummed labels for each solicitation requested. The solicitation number should appear on the bottom edge of the labels. Availability of the solicitation is limited and copies will be furnished on a first-come, first served basis until supply is exhausted. (0094)
