MPC Research on Deteriorated Pavement Pavement Yields Clues to Improved Construction
Posted: Nov 6, 2023
Researchers at the University of Utah studied a section of roadway that deteriorated prematurely to learn how to improve road construction where soft subgrades are involved. The researchers studied a geogrid-reinforced pavement system on the section of Utah State Route 10 between Muddy Creek and Emery. Based on what they learned, the improved understanding of the significant influence that native subgrade and fill materials have on the performance of pavement systems constructed on soft subgrades should result in roadway systems that will perform better and require less long-term maintenance than current practices allow.
Proving that the geogrid in this roadway system performed well and helped limit the damage that occurred to the roadway should result in the use of more geogrid-reinforced pavement systems in Utah and significant savings in the long-term cost of the pavement systems constructed using this technology.
