The Effect of Adding High-Density Polyethylene Polymer on the Engineering Characteristics for Sandy Soil

The loose sand is subject to large settlement when it exposed high stresses. This due the nature of drainage sand, which displays foundations and constructions a danger. densification sandy soils required provide sufficient bearing capacity for structures. Thus soil stabilization used avoid failure in facilities. Traditional methods stabilized such as fly ash, bituminous, cement often require an extended curing period. use polymers stabilize more extensive nowadays because does not long time addition being chemically stable. In this study, effect adding different percentages high-density polyethylene HDPE soils' engineering characteristics angle internal frictions Ø0, shear strength τ, California Bearing Ratio CBR, permeability k was studied. results laboratory tests showed that using at (0.1, 0.3, 0.6, 1, 3%) led decrease by 18% increase both friction, CBR value, about 27.2%, 180.9%, 38.6 % respectively 1%.
