Abstract:

In Kansas, mechanically stabilized earth (MSE) retaining walls are typically ; backfilled with coarse aggregate. Current backfill material testing procedures used ; by the Kansas Department of Transportation (KDOT) utilize on-site observations for ; construction quality assurance and the American Association of State Highway and ; Transportation Officials (AASHTO) Standard T 288-12 (2012), “Standard Method of ; Test for Determining Minimum Laboratory Soil Resistivity.” T 288 is designed to test ; a soil sample’s electrical resistivity, which correlates to its corrosive potential. The ; test, based on material passing through a No. 10 sieve, is considered inappropriate for ; coarse aggregates and potentially leads to over-conservative designs. Additionally, ; T 288 is run on a sample from the aggregate source, but test results may not capture ; variability of the aggregate used in construction. Electrical resistivity imaging (ERI) ; provides a two-dimensional (2D) profile of the bulk resistivity of backfill material, ; thereby reducing uncertainty regarding backfill uniformity as compared to traditional ; sampling.
