| 摘要： | The low temperature thermal cracking of asphalt pavements is one of the main causes for annually repeating expensive highway repairs. While the current Association of American State Highway and Transportation Officials (AASHTO) M 320 Table 1 binder specifications are believed to be working fairly well with most unmodified asphalt binders in controlling low temperature thermal cracks in asphalt pavements, they do not work as well for certain types of asphalt binders including physically and chemically modified asphalt binders. For this reason, a simple test method, the Asphalt Binder Cracking Device (ABCD), is proposed to characterize the low temperature properties of asphalt binder. The objectives of this study are to develop an ABCD test system and test procedures that provide accurate and repeatable low temperature characteristics of asphalt binders and to validate the ABCD test system by comparing its results with low temperature field performance data. / NOTE: Final rept. / Supplementary Notes: Sponsored by Transportation Research Board, Washington, DC. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
