Deep Soil Mixing (DSM) Treatment of Expansive Soils
The effectiveness of Deep Soil Mixing (DSM) treatment method was evaluated in terms of reducing heave movements of expansive subsoils underlying pavements and earth structures. Laboratory mix design study results were used to select a combined binder treatment approach utilizing lime and cement binders. DSM columns were designed and constructed in two pilot scale test sections. Surcharge equivalent to loads from base and surface layers was placed on top of these DSM treated sections through a fill placement. The two pilot test sections along with control sections on untreated soils were instrumented and monitored for period of two years. Monitored results showed that soil shrink-swell related movements in both vertical and lateral directions were lesser than those recorded in the untreated soil sections. Overall, this research showed the potential of DSM treatment method to minimize shrink-swell related movements from expansive subsoils of moderate depths.
