Many geoconstruction technologies, some in existence for several decades and others recently developed, face both technical and nontechnical obstacles preventing broader and effective use in transportation infrastructure projects. The second Strategic Highway Research Program Renewal Project R02 (SHRP 2 R02), Geotechnical Solutions for Soil Improvement, Rapid Embankment Construction, and Stabilization of the Pavement Working Platform, investigated the state of practices of transportation project engineering, geotechnical engineering, and earthwork construction and identified and assessed methods to advance the use of these geoconstruction technologies. Several of the identified technologies are underused in current practice, yet they offer significant potential to achieve SHRP 2 Renewal objectives (rapid renewal of transportation facilities, minimal disruption of traffic, and production of long-lived facilities). Project R02 encompasses a broad spectrum of materials, processes, and technologies within geotechnical engineering and geoconstruction that are applicable to one or more of the following elements of construction: new embankment and roadway construction over unstable soils, roadway and embankment widening, and stabilization of pavement working platforms. |
