| Summary: | acetate, styrene-butadiene styrene-block (SBS) copolymer, SBS analysis system (AAMAS) test protocols to assess relative Asphalt binders extracted from field cores were tested using asphalt concrete (HMAC) pavements. In the late 1980s, test asphalt. Asphalt modifiers included latex, ethylene vinyl chromatography (GPC), and asphaltene content (using heptane). cracking. DSR testing, high levels of oxidation as measured by FT-K during construction and sealed in cans, were tested using evaluated in the laboratory. Asphalt binders were comprised fatigue cracking was related to low loss tangent values from Fourier transform infrared (FT-IR), gel permeation FT-IR and GPC. Retained binders and aggregates were combined high amounts of large molecular size (LMS) material from GPC Highway Research Program (NCHRP) asphalt aggregate mixture In 1995, cores were obtained from these pavements and in accordance with the original mixture designs, compacted in of both modified and unmodified AC-10 and AC-20 grade pavements were constructed in Texarkana and Sherman, Texas. polyethylene, and carbon black. Asphalt binders, retained properties that affect cracking performance of hot mixed resistance to fatigue cracking. Field cores were also tested SUPERPAVE[] binder tests, dynamic shear rheometer (DSR), test results showed no correlation with the observed fatigue testing, and high asphaltene contents. SUPERPAVE[] and AAMAS the laboratory, and tested using the National Cooperative The overall objective of this study was to identify binder using the NCHRP AAMAS test protocols.
