PRELIMINARY RESEARCH FINDINGS ON THE EFFECT OF COARSE AGGREGATE ON THE PERFORMANCE OF PORTLAND CEMENT CONCRETE PAVING. INTERIM REPORT

This report focuses on aggregates used in the construction of continuously reinforced concrete pavements (CRCP). Specific chapters address (1) past research regarding aggregates used in CRCP, (2) field and laboratory investigations of CRCP, and (3) CRCP behavior and distress. The report reviews such topics as spalling and punchout distresses in continuously reinforced and jointed pavements, aggregate shape characterization using fractals, and the determination of sawcut depth using fractal analysis. Some of these activities relate directly to improving pavement performance, regardless of aggregate type used for construction. Early recommendations based on the project's significant findings have already been presented to the Texas Department of Transportation.
