Abstract

This paper presents the methods of construction, and the evaluation of three years of field and laboratory observations of 6,000 ft of stabilized soil base and subbase courses of primary highway 117; Jasper County, Iowa. The 6-in. subbase test sections were constructed by using the in-place subgrade loessial soil materials stabilized with lime, lime-fly ash, and commercial organic cationic chemical. The 7-in. base course test sections were constructed using a sand-loess soil mixture stabilized with linie-fly ash, lime-fly ash-accelerating agent, and type I portland cement. The fly ash was obtained from two sources. Sodium carbonate and sodium chloride were used as accelerating agents in two sections of lime-fly ash base course. The surface course was 3 in. of an asphaltic concrete mix.
