This report describes an economical process for admixing lime with mineral aggregates during the production of asphaltic concrete pavement. In this process, the optimum amount of lime required is added to the field sand to treat the mineral aggregates in the asphaltic concrete pavement; the field sand, in turn, carries the lime to the other mineral aggregates during the blending, mixing, and drying process. After being treated with the lime, the field sand is placed in a stockpile and delivered to the production plant as needed. In our tests, treated field sand stockpiled for seven months showed neither evidence of recarbonization nor signs of deterioration.
