Abstract
The analysis and application of repeated load test results of soils are approached from the point of view of improving the design of subgrades. The soils dealt with are unsaturated sandy loam and sandy clay loam. First, the characteristics of soils under repeated load are investigated by performing a simple repeated load test on the soils; next, the fatigue problem of soils are studied; thirdly, several instances of introducing the test results to the design problems of subgrades are described. Consequently, the results are found applicable to the design and construction of the subgrade.
