High-Volume Recycled Materials for Sustainable Pavement Construction

Given the increasing rate of demolition, it is essential to effectively reuse demolition waste in order to conserve non-renewable natural resources. Decreasing natural resources, as well as increasing problems with waste management, ecological hazards, landfill limitations and increasing distances between the natural resources and consumption markets, support the idea of recycled wastes to be used for new concrete production. The reduction in carbon footprint by the use of recycled materials is becoming a key solution to decrease the total environmental impact related to construction industry. The proposed study aims at developing sustainable concrete materials for infrastructure applications. The main idea is to incorporate high volume of recycled materials in concrete production (at least 50% of the mass of solids) to reduce cost and decrease carbon footprint without mitigating performance and service life. The main emphasis for this concrete is its use in pavement construction. Recycled materials include both coarse and fine recycled concrete aggregate (RCA), supplementary cementitious materials (SCMs), fillers, glass powder, and alternative binders. The study will evaluate fresh and hardened properties and durability aspects of such novel "green concrete" material. The study will explore the feasibility of using these recycled materials in single lift and 2 lift-concrete pavement (2LCP) construction systems. The study will also explore other materials systems such as controlled low strength materials (CLSM) that utilize high volume of recycled fine materials. Field implementation will be carried out to investigate in-situ performance of the proposed concrete in different geographic locations in the United States (Illinois and Oklahoma). The final scope of the project and selection of field demonstration sites will be evaluated with other investigators as well as government and private partners interested in this project. The project will also evaluate life cycle cost analysis (LCCA) in order to determine the economic impact and environmental benefits of using such eco-friendly materials in infrastructure applications
