IDENTIFICATION OF FROST SUSCEPTIBLE AGGREGATE AND THEIR USE IN CONCRETE OR BITUMINOUS PAVEMENTS

The present study was designed to investigate the significance of the details of the pore structure on the frost resistance of concrete aggregates. Likewise, the surface failiure taking place in concrete and bituminous pavements exposed to deicers was closely analyzed. Two approaches were used to accomplish the objectives of this investigation: Statistical Analysis of observational data, and the Experimental Method. In addition, a simplified theoretical analysis of the freezing process was offered. Based on field data, a discriminating function was obtained to differentiate between aggregates of varying frost resistance. This function was derived by taking into consideration the details of the pore structure of coarse aggregates in concrete pavements. (Author)
