Abstract

Degradation of aggregate in concrete can be caused by erosion or fracture over time. Extensive studies have been conducted on concrete mix design and composition of cementitious materials to improve the performance and durability of concrete. This project is a collaboration between researchers at UAF and Washington State University. Project tasks include application of a promising testing protocol for long-term concrete erformance characterization; evaluating damage accumulation and concrete durability at cold temperatures with
damage mechanics models; developing specifications on performance criteria and service life predictions, and providing guidelines for ADOT&PF to evaluate concrete performance and safety. Study outcomes will benefit the construction and maintenance of transportation infrastructure in cold climates.
