Roller-Compacted Concrete Specifications & Uses - CEMEX USA

RCC installs faster, costs less and is more durable than other pavements materials.

Roller-compacted concrete (RCC) helps your paving budget go the extra mile by delivering the high strength and long-term durability of concrete with the low cost and fast installation of conventional pavement materials.

Install it today. Drive on it tomorrow.

RCC was developed in the 1970s as an affordable pavement solution that would stand up to high volumes of heavy loads while resisting freeze-thaw damage.

Because it's a drier mix than traditional concrete, RCC is quickly installed with high-density asphalt paving equipment and compacted using vibratory rollers - without forms, rebar or extensive finishing. You simply mix it, place it, compact it and cure it.

RCC minimizes construction costs, and keeps traffic flowing, typically within 24 hours.

High performance. Without high costs.

While RCC's installation costs are comparable and frequently lower than asphalt pavements, its long-term maintenance costs are far lower, giving it an average of 30% savings over the life of a road.

The superior strength and durability inherent in RCC infuse it with high-performance properties that eliminate common problems that drive up the long-term costs of maintaining streets built with other pavement materials.

With RCC, potholes and street rutting are history. Surface cracking due to heavy loads becomes nonexistent. Fuel and hydraulic fluid spills no longer deteriorate your pavement. And high temperatures won't soften your streets.

Lower lifecycle costs and proven performance make RCC your smartest choice

RCC Attributes	RCC Benefits
High flexural strength (550 - 800 psi)	Supports heavy traffic Withstands concentrated loads Spans localized soft areas Cuts maintenance costs Reduces traffic disruptions
High compressive strength (4,000 - 6,000 psi)	Supports heavy traffic Withstands concentrated loads Eliminates potholes & rutting Cuts maintenance costs
High density / low absorption	Increases pavement durability Resists freeze-thaw damage Eliminates oil-seepage damage
Low water content	Increases pavement strength Reduces pavement permeability Enhances pavement durability Reduced Shrinkage / cracking
Aggregate interlock	Increases joint performance Improved load transfer reduces vertical faulting
High solar reflectivity	Mitigates urban "heat island" effect Reduces pavement lighting needs Fosters environmental compliance
No rebar or dowels	Speeds construction time Reduces labor costs Simplifies site prep and setup Eliminates steel corrosion issues
No forms or finishing	Speeds construction time Reduces labor costs Simplifies site prep and setup

Product Description

The basic ingredients of RCC are the same as for conventional concrete: sand, aggregates, cement, and water, however the quantities are different. Mix designs may vary based on the job application. RCC is a zero slump concrete mix that is placed using high-density asphalt pavers and compacted with 10 ton rollers similar to the way hot mix asphalt is placed.
