PCA Launches Updated RCC Design Manual

The Portland Cement Association (PCA) released the second edition of its Design Manual for RCC Spillways and Overtopping Protection.

The newest edition provides the latest in design trends, mix designs, control sections, and construction means and methods for roller-compacted concrete (RCC) spillways and overtopping protection. A new chapter on performance highlights the 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 spillway capacity and improve the safety of deficient dams,” said Joshua Gilman, PCA manager, water resources and geotechnical markets. “We are pleased to offer an updated design resource for water resource professionals, including 20 years of data and case study information.”

For more than 20 years, the manual’s first edition served as the preeminent design reference for practitioners, regulators and contractors in the water resources industry. Cement-based products such as RCC are being employed across the world on water resources projects with positive results and improved quality of life. The application has been implemented at more than 196 dams across 30 states.
