Triaxial shear strength characteristics of some sand-asphalt mixtures

Anderson, K.O. / Haas, R.C.G. / LaPlante, A.D.

Asphalt stabilization, determined strength relationships of cutback asphalt, emulsified asphalt, hot-mix and foamed asphalt mixtures were investigated by triaxial compression testing of cured and water-immersed specimens; results show that for fine, uniform and rounded quartz sands used, foamed asphalt process results in superior shear strengths of cured specimens, compared to other processes; it is also shown that at same estimated bituminous film thickness, addition of limited amount of fines passing No. 50 sieve size results in increased cured cohesive strengths.
