The Effect of Plasticity and Quantity of Fines on Stability of Soil-Gravel Mixtures

Abstract

Variation of Compressive Strength at 15 psi Lateral Pressure with Quality of Soil 57 16. Variation of Angle of Internal Friction with Quality of Soil viii No. 30 sieve) was high. For this case high plasticity indices (15!?-20!?) did not harm the mixture. When the percent passing No. 30 sieve became high, mixtures with low dust ratios were more stable and high plasticity indices had em adverse effect on the stability of the mixtures .
