SOIL STABILIZATION FOR LOW-VOLUME ROADS. VOLUME 4 - COST-BENEFIT ANALYSIS. PHASE II - FINAL REPORT

Volumes 1, 2, and 3 of this report are guide booklets for administrators, road engineers, and road builders respectively. These guide booklets were developed to provide information on the use of four stabilization treatments, i.e., lime, asphalt, cement, and lime-fly ash in the construction of low-volume roads. Volume 4, contained herein, documents the use and cost-benefits of the above referenced four soil stabilization treatments used in the construction of low-volume roads. A life cycle costing economic analysis procedure for evaluation of pavement alternatives, i.e., gravel surfaced road and chip and seal surfaced road with and without the conditions of soil stabilization treatments is illustrated. A data base for 24 case histories with stabilization and equivalent pavement without stabilization is presented and analyzed to show benefits of stabilization. The study concludes that to realize potential benefits, soil stabilization treatments should be considered as a design alternative in all climatic regions when specification materials are not available in abundance. Additionally, soil stabilization should also be considered: to provide less frost susceptibility; to provide conservation of good quality aggregates; to provide uniform strength for widening an existing roadbed; and to avoid raising the level of an existing roadbed.
