Abstract: Since its first installation at the Virginia Smart Road in 1999, use of the new class of steel reinforcing netting to enhance the performance of hot-mix asphalt (HMA) overlay against reflective cracking has grown at a fast rate in the United States. Several states initiated experimental sections incorporating steel reinforcement to investigate its effectiveness in retarding the reflection of cracking in HMA overlays on top of existing rigid pavement systems. Concurrently, a theoretical study was undertaken to investigate and quantify the benefits of this emerging technology. Three-dimensional finite element (FE) techniques were used to validate the effectiveness of steel reinforcement in delaying the reflection of cracks. Both the effects of traffic and thermal loading on the overlay fracture behavior were considered in the analysis. While traffic loading was simulated by the movement of a tire over the concrete joint, a sequential coupled heat transfer analysis was used to investigate the effects of temperature on the pavement structure.
