Aggregate Quality as Related to Flexible Pavement Performance
This research study has been concerned with the evaluation of low quality aggregate for use in paving mixtures. The mixture evaluation was carried out using environmental simulation, moduli response, indirect tensile strength and structural simulation of pavement responses. The review of data indicates that both coarse aggregate and fine aggregate are equally responsible for mixture durability. The use of low quality sand might, in fact, have an equally detrimental effect when compared to the effect of coarse aggregate. For mixtures in which low quality sand was replaced with limestone sand, the mixture performance exhibits a two-fold improvement. The use of sulfur as a mixture additive similarly improved mixture performance. The simulation of pavement performance indicates that two inches of a 301 mixture prepared with locally available aggregate is equivalent to one inch of asphaltic base course 301 prepared with a limestone material from Franklin County.
