Every year billions of tax payers’ dollars are spent in an attempt to repair and maintain the crumbling four million miles of roads and highways that span the country. The US government adds nearly 36,000 lane-miles of roadway per year and the amount of deterioration is growing faster than can be repaired (ARTBA, 2013). New systems are being developed in an attempt to improve road conditions and slow the degradation of the country’s roadways. This project proposes a new system, incorporating smart materials, in an attempt to solve the issues caused by failing dowel-jointed rigid pavements. The proposed dowel system, based on a magnetorheological (MR) fluid dampening system, would provide the appropriate stiffness in the dowel in response to various dynamic loads due to vehicular traffic.
