QUALITY CONTROL AND PERFORMANCE CRITERIA FOR GROUND MODIFICATION TECHNOLOGIES

摘要

Ground modification technologies-are we using the right quality control tests to ensure that performance objectives will be satisfied? Construction of transportation and infrastructure systems over the past several decades is replete with applications of new ground improvement technologies. Many of these new technologies are patented and/or require specialized equipment and contractors. Owners are often at a disadvantage to judge the performance of the many types of ground modification available. The need for QC/QA and its integration with design and performance criteria are explored and discussed. Following background development and definitions, a conceptual framework for linking QC/QA with performance-based criteria for ground modification techniques is proposed.
