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.

The rigid pavement (RP) database contains historical distress data obtained from more than 400 continuously reinforced concrete pavements (CRCP) and jointed concrete pavements (JCP) across the state of Texas. Data collection efforts began in 1974 and have been undertaken periodically up to the present. The database contents include such performance-related variables as punchouts, patches, spalling, ride score, crack spacing, and deflection basins, as well as such inventory variables as location, design thickness, coarse aggregate type, climate, soil characteristics, date of construction, and overlay status. Taken as a whole, the RP database comprises a unique asset for empirical investigation of factors affecting long-term pavement performance in Texas.

"This report provides technical information on pervious concrete's application, design methods, materials, properties, mixture proportioning, construction methods, testing, and inspection. The term 'pervious concrete' typically describes a near-zero-slump, open-graded material consisting of portland cement, coarse aggregate, little or no fine aggregate, admixtures, and water." [p. 1]
