Book Description
This investigation consists of full-scale testing, laboratory evaluation, and presentation of improved design criteria using membrane-enveloped fine-grained soil (MESL) within pavement layers. The research provides a description of proven materials and necessary construction techniques. Cost predictions are developed using these materials and techniques and predictions are compared with actual costs. Material characterization was performed in the laboratory and field using dynamic vibratory testing. The characteristics of materials employed in a full-scale MESL test section were used in a structural analysis of this type of load supporting media subjected to moving repetitive loadings. This analysis of stress conditions was facilitated by computer solution. Limiting criteria based on the shearing strain in the subgrade and the number of stress applications were developed as failure criteria. These criteria were formulated using performance data and model analyses. A design method using materials characterization, structural analysis, and failure criteria was presented to facilitate incorporation of a MESL technique into the design engineer's repertoire.
