Title: Roller Compacted Concrete
Description:
Session Code: CO6 Roller-compacted concrete, or RCC, takes its name from the construction method used to build it. RCC is placed with conventional or high-density asphalt-type paving equipment, then compacted with vibratory rollers. RCC has the same basic ingredients as conventional concrete - cement, water, and aggregates, such as gravel or crushed stone. RCC needs neither forms nor finishing, nor does it contain dowels or steel reinforcing. RCC pavements are strong, dense, durable, and sustainable. These characteristics, combined with construction speed and economy, make RCC pavements an excellent alternative for parking and storage areas; port, intermodal, and military facilities; highway shoulders; streets; and highways. RCC can also be used in composite systems as a base material. This presentation discusses the benefits and applications of RCC for pavements, the process for proper materials selection and testing, durability, workability, and strength determination, and preparation of mixture designs for RCC using various methods, as well as the specifications, construction practices, placement methods, field testing, and inspection necessary to ensure quality projects for pavement applications.
