Abstract
The nation's infrastructure is showing its age. The signs are obvious with structure distress, lack of functionality, and failure reported frequently over the last several decades. Specialty geotechnical construction techniques may provide a solution to help reduce the cost and increase the speed of repairing this infrastructure. Direct and indirect examples of the infrastructure woes include: ASCE's Report Card disclosing repeated low grades dating back to 1988; High-profile incidents like failure of the Oroville Dam spillway in California in February 2017, and the I-35 Mississippi River bridge collapse in Minnesota in August 2007; Lack of spending at state and federal levels to maintain even the current infrastructure condition specifications (e.g., in Missouri, transportating spending is at its lowest levels since 1992; the budget for 2018 is $325 million versus $1.3 billion in 2011); Declining revenue for state DOT funds because the federal gas tax rate has not changed since 1992, and today's vehicles are more fuel-efficient.
