A Literature Review of Approach Slab and Its Settlement for Roads and Bridges in Wyoming

The purpose of this project is to perform a literature review of the approach slab and the associated settlement problems at bridge approaches, as well as provide the Wyoming Department of Transportation (WYDOT) with potential solutions. Research outcomes obtained from the proposed work plan will be presented in a manner that will be suitable for application and adaptation in the State of Wyoming. Benefits from this project are anticipated to be: reducing excessive settlement in the approach slap; eliminating road bumps at the approach slab; improving the road and bridge rideability; providing a more cost-effective and improved approach slab system; providing more rational and cost effective procedures for remediation of existing problematic approach slabs; lowering the maintenance cost and time; and increasing the safety of the public using the roads and bridges throughout Wyoming. This project will use a literature review of comprehensive literature pertinent to the reinforced approach slap and a nationwide survey to formulate conclusions and recommendations.
