Field Studies on Rigid Pavement Sections Built on Stabilized Sulfate Soils

摘要

This paper reports results from an on-going research study conducted to evaluate the stabilization potentials of Sulfate Resistant Type V Cement, Class F Fly ash & Type V Cement, Ground Granulated Blast Furnace Slag, Lime & Polypropylene fibers and Lime. Rigid pavement test sections were constructed on the five sections of stabilized subgrade soils and these sections were instrumented and monitored for seventeen months. Instrumentation data obtained from strain gauges and pressure cells as well as elevation surveys were analyzed to address any heave related movements and load carrying potentials of treated subgrades. Overall, based on the monitored data, Cement-Fly ash, GGBFS and Type V Cement treatments showing effective treatments for stabilizing sulfate bearing soils with no heave distress.
