Due to growing interest nationwide and in New York, a two-phase laboratory program was undertaken to measure resilient and tensile properties of New York's top-course Mix Types 6F and 7F. Resilient modulus was measured on 28 asphalt concrete mixes at 40, 77, and 100 F using repeated-load indirect-tension test equipment according to ASTM D 4123-82 procedures. Indirect tensile strength and stiffness were measured with static tensile strength equipment at speeds of 2 in. per minute at 77 F only. Test properties of the 28 mixes are summarized in this report.
