Abstract
This Phase I project will investigate using scrap tires to form a protective system for mitigating local scour around bridge piers. Local scour is the erosion of the riverbed around bridge piers, which is induced by the recirculating juncture flow at the intersection of the pier and the riverbed. Bridge failure caused by this phenomenon has long been an important issue with respect to both public safety and maintenance costs. Average total losses from the resulting damage can run up to $100 million annually. Nearly half a million bridges nationwide are potentially affected by local scour. A honeycomb structure of scrap tires can mitigate local scour by modifying the vortical flow in the vicinity of the pier and riverbed. Moreover, this design is judged to be a highly desirable supplement to traditional methods of recycling scrap tires with the potential of recycling billions of tires. A complete scaling analysis will be conducted to determine the important parameters for experimental investigation. Subscale scouring experiments will be run and results will be used to compile a general design model for the implementation of the honeycomb device.
