TRB releases ‘Optimization and Management of Materials in Earthwork Construction’

The Institute of Transportation at Iowa State University has released a report exploring optimization and management of materials in earthwork construction designed to address pavement cracking due to improper management of pavement geotechnical materials, settlement of soil above a pipe due to improper compaction of the backfill, and permeability of mixed-subgrade soils, the Transportation Research Board (TRB) reports.
