Paper - There is an increasing need to use manufactured sands in pavement concrete in areas where sources of natural sand are not available or are being depleted. However, manufactured sands usually do not meet the ASTM C33 gradation requirements and have high micro fine contents, poor shape, and poor texture. A logical method of concrete mixture design has been developed based on the previous work done by the International Center for Aggregates Research (ICAR). Laboratory results have shown that the proposed mixture design can save up to
150 lb/yd3 of cement compared to mixtures designed by ACI 211 without compromising strength or durability. Therefore, this proposed mixture design has the potential to produce less expensive and sustainable concrete without sacrificing performance.
