Compaction of Difficult Soils and Resilient Modulus Testing

摘要

The 12 papers in this volume are arranged in two groups. The first six paperspresent information on various issues that relate to compaction of soils, including the impact of the rock correction equation method on construction control of engineered fills when the material being compacted contains gravel; the importance of property addressing the purpose of a project in the contract specifications in achieving the desired end results on construction projects; the results of an investigation of instability of embankments built with silty clay, and steps taken to mitigate the problem; the findings from a review and comparison of the compaction criteria used for construction of soil hydraulic barriers, and a discussion of the advantages and disadvantages of the different criteria; the mechanical properties of expanded polystyrene, which is used as a lightweight fill and embankment earth material; and the results of an investigation of the effects of construction methods on widening of roads on soft soils using a small centrifuge. The second group of six papers covers resilient modulus testing.
