A GUIDE TO DETERMINING THE OPTIMAL GRADATION

This guide provides a means to determine the optimal gradation of sand and coarse aggregate materials for highway concrete pavements. The guide is, to a major extent, based on the use of a computer model (1, 2) developed by G. M. Idorn Consult A/S (GMIC) for estimating the porosity remaining after the packing of fine and coarse concrete aggregate.
