Roller-Compacted Concrete Pavements as Exposed Wearing Surface Version 1.2 – September 4, 2014 . This document provides a guideline specification useful for developing project specifications for roller compacted concrete (RCC) as an exposed RCC pavement surface, that may or may not be diamond ground for smoothness and/or texture.
-195RCC model, which is a stationary concrete batching plant that is specially designed for production of RCC (Roller Compacted Concrete), is designed for maximum capacity, flexibility, efficiency and reliability for producing of RCC along with all types of high quality concretes in mass production.
Mix Design . Selection of proper materials and correct proportioning is critical to the production of quality Roller Compacted Concrete mixtures.
Course Title Roller Compacted Concrete Pavements The Roller Compacted Concrete (RCC) Pavements course provides detailed overviews of RCC properties and materials, mixture proportioning, structural design issues, and production and construction considerations, plus troubleshooting
Roller-compacted concrete pavement (RCC) has been used for several decades in specific applications, mostly for heavy-duty industrial pavements. But it has the drawback of a rough surface with little aesthetic appeal, leading some owners to use it as a subbase with an asphalt overlay. A contractor ...

Development of roller-compacted concrete (RCC) caused major shift in construction practice of mass concrete and pavement slabs. Large amounts of mineral admixtures (fly ash, slag, and natural pozzolan) are used in RCC to reduce both adiabatic temperature rise of …
The RCC Pavement Council is a volunteer industry trade association representing the interest of those involved with the construction of Roller Compacted Concrete Pavements. The RCC Pavement Council supports Research and Promotion to improve the quality of RCC pavements and expand their use in a responsible and sustainable manner.
4.0 PRODUCTION AND MATERIAL QUALITY – TESTING METHODS, PROCEDURES, AND REPORTING 4.1 Roller Compacted Concrete Constituents RCC is generally produced by mixing aggregate cement, pozzolan, and water. Occasionally, admixtures will be introduced into the RCC in order to modify a particular behavior.
As evidence, ASTM International is formalizing a method for making a cylindrical specimen of RCC in a gyratory compactor. Test Method for Preparation, Compaction and Density Determination of Roller-Compacted Concrete Specimens by means of the Superpave Gyratory Compactor is being developed by Subcommittee C09.45 on Roller-Compacted Concrete.
The Vince Hagan RCC Roller Compacted Concrete Horizontal Mixer is the highest production and most portable RCC mixer on the market. It can mix high and low slump, slurry mixes, cement treated base and roller compacted concrete.
Production . Roller Compacted Concrete can be produced in any type of equipment that will provide uniform mixing of the cement, aggregates, admixtures, and water.
By: Matthew W. Singel, PE Roller-Compacted Concrete (RCC) production for pavements raises many questions for the novice, from mix design, to admixtures, to plant equipment. A common question is, "What equipment is best for producing/mixing RCC for pavements?"
Roller compacted concrete (RCC) is an extremely dry concrete which is very difficult to compact by the normal methods used for workable concrete. RCC is used for the construction of dams and pavements. Camelway Machinery. ... Production of Roller Compacted Concrete Plant.
Roller Compacted Concrete differs from conventional concrete in its gradation requirements. The different gradation requirement comes from the need of the Roller Compacted Concrete aggregate skeleton to be consolidated under compaction efforts from the …
Mixed and placed similarly to roller-compacted concrete, proprietary additives plus finishing materials and processes enhance durability, rideability, and appearance. "We'd been doing roller-compacted work and saw the value of it being fast and durable, but the appearance turned everyone off," …
ROLLER-COMPACTED CONCRETE 1. Purpose. The purpose of this manual is to provide information and guidance on the use of roller-compacted concrete (RCC) in dams and other civil works structures. Elements discussed include investigation and selection of materials, mixture proportioning, material properties, design and
We are trying to use regular transit mixers to produce roller compacted concrete (RRC). Most of our markets do not have a central mixer available. We have developed a mix that discharges fairly well from a non-paving mixer. ... We are considering washing out the units every hour of production and then coating the mixer blades and drum with a ...
The Vince Hagan RCC Roller Compacted Concrete Horizontal Mixer is the highest production and most portable RCC mixer on the market.It can mix high and low slump, slurry mixes, cement treated base and roller compacted concrete.
Roller Compacted Concrete is a mixture of cement, aggregates, and low water content mixed in a continuous mix pug mill. Cost savings in using RCC are achieved from faster production rates, no reinforcing steel used, and reduced labor costs.
Because the Roller Compacted Concrete base allows for a reduction in the thickness of the conventional concrete pavement, multi-layer systems can be used cost-effectively in highway, airport, and heavy industrial applications and should provide the same long-term performance as full-depth pavements.
