Quarry By-product Fines for Otta Seal Surfacing of Local Roads

An Otta seal is a cost-effective surface treatment that is formed by adding graded aggregate to a thick application of soft binder. It is worked into the aggregate as traffic rolls over it. This project will examine the use of quarry by-product fines, a leftover material from crushed rock extraction found in abundance in Illinois, as aggregates in Otta seals. Researchers will review design parameters as well as conduct lab testing to prepare mechanistic-based design and construction guidelines for Otta seals with quarry by-product aggregates. Effectively using Otta seals with quarry by-product aggregates will reduce operational costs and maintenance needs as well as minimize aggregate segregation and provide environmental benefits.
