• Abstract:
  The primary objective of this study was to evaluate the effects of the variations in properties of concrete mixes composed of limestone and siliceous river gravel aggregates on the design and performance of CRC pavements. Laboratory testing of concrete mixes composed of these two aggregate types was carried out at the Balcones Research Center, The University of Texas at Austin. A statistical analysis was performed on these laboratory measurements to develop models to predict concrete properties for the two aggregate types. These models reflect differences in the properties of concrete mixes composed of limestone and siliceous river gravel aggregate types. Utilizing these concrete property models and formulating a factorial based on environmental conditions, pavement geometry, and steel reinforcement variables, an analysis was performed with the CRCP-4 computer program. The pavement performance predictions from this program were used to develop aggregate based CRC pavement steel reinforcement design models. 1he variation in concrete properties due to the choice of limestone or siliceous river gravel aggregates was accordingly translated into different steel reinforcement requirements for the two aggregate types. As a further refinement of the CRC pavement design procedure a concept of design reliability based upon the observed field performance of pavements has been developed. This concept, which identifies the aggregate type, should be incorporated into the criteria for developing design recommendations.
