SHRP 2 R02: Geotechnical Solutions for Transportation Infrastructure: A Web-Based Toolkit

摘要

The second Strategic Highway Research Program (SHRP 2) was created by the U.S. Congress to address challenges of moving people and goods efficiently and safely on the nation's highways. Geotechnical transportation issues are addressed under the SHRP 2 Renewal Focus Area, in which the goal is to develop a consistent, systematic approach to the conduct of highway renewal that is (1) rapid, (2) causes minimal disruption, and (3) produces long-lived facilities. The R02 project is aimed at identifying geotechnical solutions for three elements: (1) construction of new embankments and roadways over unstable soils; (2) widening and expansion of existing roadways and embankments; and (3) stabilization of working platforms. The project includes evaluation of the effectiveness of mitigation measures; a catalog of materials and systems for rapid renewal projects; guidance for design and QC/QA procedures; methods for estimating costs; and sample specifications for the identified geotechnical materials, systems and technologies. This has all been integrated into a web-based, interactive information and guidance system to provide the data necessary for determining the applicability of 46 specific ground improvement and geoconstruction technologies to specific projects. This paper describes the information and guidance system and how it can aid users in accessing information about and engineering with these solutions.
