The purpose of this investigation is to provide comparative strength data between silty sand and lateritic soil stabilized with Penemulsion and conventional asphalt emulsion. The comparative strength values were attained for liquid asphalts contents from 2-6 percent by the use of the Hveem stabilometer and cohesiometer tests. The comparative unconfined compressive strength of the selected stabilized mixtures was determined after curing for a period of 3, 7, 15 and 28 days. The undrained triaxial compression test was conducted to see the shear strength parameters of the stabilized mixtures. Materials, apparatus and procedures, and results are presented. It is concluded that Penemulsion has nearly the same effect on density of silty sand and lateritic soil as the SS-K emulsion. All R, C and R sub t values tend to be slightly higher for the Penemulsion mixtures than the SS-K emulsion for both types of soil. The amount of either type of emulsion for maximum R and R sub t values is about 5 percent for silty sand, but for lateritic soil it is about 6.5 percent. Silty sand-Penemulsion mixture gives 10-15 percent of R value higher than the SS-K one, but for lateritic soil an increase value is only 6 percent. The angle of shearing resistance of lateritic soil mixed with either kind of emulsion is about 24 degrees, and that of silty sand mixture is about 29 degrees.
