First off, sorry for the cheesy Halloween tie-in. The other day I read an interesting paper in the Journal of the Transportation Research Record, No. 2045, of the Transportation Research Board (TRB). The paper was titled: “Evaluation and Recommendations for Flowfill, and Mechanically Stabilized Earth Bridge Approaches.” I’ll post the full citation below. (Photo from FHWA NHI Soils and Foundation Course Slides, NHI Course No. 132012)
The authors describe the standard of practice for Colorado DOT (CDOT) projects for the last 16 years with regard to the construction of bridge approaches in an attempt to eliminate the problem with the “bump at the end of the bridge”. They discuss some of the common reasons for problems with approaches, and some possible solutions. Click through for more.
