Experimental Study on Expansion Characteristics, Frost Heaving Characteristics of EPS Beads Improved Expansive Soils

Abstract:

Proposed EPS beads for the improvement of expansive soil in cold regions. Based on laboratory soil test study the feasibility and mechanism of the EPS beads improving expansive soils. Through four sets of comparative test with different contents of the EPS beads, the result indicates: The expansion rate of the soil, frost heave amount decreases with the increase in EPS beads content, EPS beads can effectively inhibit the expansion of expansive soil and frost heaving, proposed the optimal dosage.
