It is proposed that existing pavements can be pulverized in place, sufficient quantities of Class C fly ash and water added, and the resulting mixture compacted to produce a stabilized pavement base section. A laboratory study was conducted to evaluate the degree of stabilization that could be attained and the physical factors influencing the degree of stabilization. Amount and maximum diameter of hydrocarbon-bound particles, gradation of mineral aggregate, fly-ash content and use of a retarder were studied. The laboratory study was supplemented by information obtained from construction of a field-test section. Influence of the self-cementing fly ash on the recycled mixtures was evaluated on the basis of compressive strength, CBR and durability as evaluated by vacuum saturation in accordance with ASTM C-593. The study indicates that the proposed recycling procedure is both technically and economically feasible.
