Unsaturated flow phenomena impact all the geotechnical engineering applications. Requirements the understanding include seepage, shear strength, and volume change behaviors of unsaturated soil are important. Since several researchers have put efforts to conduct a potential of biopolymer for soil improvement for the last decade. This paper aimed to conduct a comprehensive experimental study on soil water retention curve (SWRC) and a permeability function prediction of para rubber (PR) biopolymer treated sand. Sand-para rubber (SPR) mixtures were prepared with sand being the base material and with different PR contents (15%, 17.5%, 20%, and 22.5%). A series of laboratory tests were conducted including the filter paper method and falling head test. The results showed that the wetting SWRC of the four SPR mixtures is significantly different compared with untreated sand which tends to give a higher value of saturated volumetric water content and water entry suction. The permeability test result displayed that the values of saturated hydraulic conductivity decreased with increasing PR content. The shape of the unsaturated hydraulic conductivity curve is quite similar for all SPR mixtures but values vary in three orders of magnitudes compared with a value of untreated sand. This experimental study showed the remarkable effectiveness of the in the wetting SWRC shape and hydraulic conductivity function of the poorly graded sand. The results also indicated that the para rubber significantly influenced on the pore size distribution of the SPR mixtures.
