The Portland Cement Association’s second edition of Design Manual for RCC Spillways and Overtopping Protection provides the latest insights on design trends, control sections, and construction means or methods surrounding roller-compacted concrete for water resources infrastructure. Observing best practices from projects in service for 40-plus years, they have added a new chapter on performance to highlight design criteria that should be used to construct RCC hydraulic structures that are durable and sustainable in all-weather environments.

“The use of RCC for spillway construction is now the fast, resilient, and proven method to add critical capacity and improve the safety of deficient dams,” says PCA Manager, Water Resources & Geotechnical Markets Joshua Gilman. “We are pleased to offer an updated design resource for water resource professionals, including 20 years of data and case study information.”

Over more than two decades, he adds, the manual’s first edition has served as the preeminent design reference for practitioners, regulators, and contractors in the water resources industry. The new edition illustrates how cement-based products such as RCC are being employed across the world on water resources projects with positive results and improved quality of life. Engineers at PCA and allied groups have tracked RCC specifications at upward of 200 dams across 30 states.
