摘要: Based on comprehensive literature review and repeated load testing an Arkansas subgrade soil, a test protocol for permanent deformation of soils was established. This is to be used in Phase II this study evaluate behavior soils. The basic configuration program proposed include: confining pressure 21 kPa (3 psi), frequency 1 Hz, rest period 0.9 second, duration 0.1 limitation application 10,000 repetitions. Three moisture levels (105%, 110%, 120% optimum content) three density (90%, 95%, 100% maximum dry density) will fabrication specimens with kneading compactor. throughout the next phase research seven additional
