Chemical stabilization of baui sand dunes in iraq 1. Effect of some soil stabilizers on the infiltration rate of sand-

Abstract

In this study, the effect of soil chemical stabilizers including polyvinyl alcohol 125,000 (PVA) (0.2% and 0.4%); ferquatac resin emulsion RB-50 (F.E.) (0.14, 0.18, 0.2 and 0.4 lm'2); bitumen emulsion Al-55 (B.E.) (0.3, 0.4, 0.5 and 1.0 lm"2); aquapol resin 35-0019 (Aql) (0.33% and 0.66%) and aquapol resin 35-0031 (Aq2) (150, 175, 200 and 250 gm m ) on the infiltration rate of Baiji dunes sand was investigated. The results indicated that, both PVA concentrations increased the infiltration rate; whereas, the remaining chemicals reduced it. The reductions in the infiltration rate caused by F. E. (0.2 and 0.4 m"2); B. E. (0.5 and 1.0 1 m"2); Aql (0.66%); and Aq2 (250 gm m ) rendered the samples impermeable. While, the infiltration rates under the remaining concentrations of these chemicals were in excess of the minimum acceptable rate of 0.25 cm hr" .
