A Life-Cycle Cost Approach of Recycled Materials in Infrastructure Rehabilitation

  • The future of engineering will become highly reliant on the use of recycled materials to balance the use of virgin materials and sustain resources. Altering the current design policies and practices will require substantial evidence in the performance and cost of recycled materials. Research has shown that materials like recycled asphalt pavement (RAP) and recycled rubber can be integrated into new pavement projects with comparable or better expected performance to traditional design. To determine the long term cost effects of recycled materials in pavement design, a manual life-cycle cost analysis is implemented to three roadway alternatives. Each alternative is subject to a performance prediction model which allows the planning of maintenance and rehabilitation strategies for the service life of the road. The present value of each alternative is found, and the RAP is shown to be a more cost-effective means to a road project than that of a traditional project.
