Title:

MATERIALS REFERENCE LIBRARY. ASPHALT SELECTION PROCESS

Accession Number:

00494618

Record Type:

Monograph

Abstract:

The Strategic Highway Research Program (SHRP) contractor, The University of Texas at Austin, will develop and operate a Materials Reference Library (MRL) containing sufficient quantities of selected asphalts and aggregates which will be used throughout the SHRP research program. Thirty asphalts, representing the output of approximately 40 percent of the refineries in the U.S. and Canada, will be sampled and stored in the library. The rationale and procedures used in the asphalt selection process are described in this report. The asphalt cements represent a wide range of field performance histories, crude oil sources, refinery practices, and physical and chemical properties. The selection criteria related to these aspects are discussed and include the following: pavement performance; crude oils, including physicochemical and performance-related properties of asphalts produced from them; and refinery processes used in the manufacture of asphalt.
