Lime-Fly Ash-Aggregate Base and Subbase Courses

by Alfred B. Crawley, Mississippi State Highway Dep, United States,

Document Type: Proceeding Paper

Part of: Serviceability and Durability of Construction Materials


This paper describes the use of lime-fly ash-aggregate (LFA) base and subbase courses for highway pavements. This type pavement course is considered as an alternate to cement treated bases (CTB) to provide strength characteristics similar to CTB without the cracking and resulting poor durability of pavements constructed over CTB.
