Performance Comparison of Abutment and Retaining Wall Drainage Systems

Drainage behind abutment walls and retaining walls is vital to the performance of the abutment and approach slabs as it relates to potential settlement and rideability. The drainage system must retain the soil backfill while allowing water to pass out from behind the wall providing hydrostatic relief. Lack of proper drainage behind abutment and retaining walls can cause damage to the abutment walls, retaining walls, approach slabs, and expansion joints. Settlement at these locations can cause unsafe driving conditions. This research will conduct a benefit analysis comparing Ohio Department of Transportation (ODOT's) current process of two feet of porous backfill with prefabricated composite drainage systems. The benefit analysis should reflect systems with potential to demonstrate a cost benefit. To accomplish this research, the scope of work should be divided into two phases. Phase 2 is contingent upon successful completion of Phase 1 and written authorization from ODOT's Research Program. The scope of work should include, at a minimum, the activities noted below. Additional tasks may be included in the proposal by the research team as appropriate to ensure achievement of research objectives.
