Roller-compacted concrete (rcc) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement. Roller-compacted concrete, or rcc, takes its name from the construction method used to build it it's placed with conventional or high-density asphalt paving equipment,then compacted with rollers roller-compacted concrete has the same basic ingredient as conventional concrete: cement, water, and. Soil laboratory compaction techniques applied to roller-compacted concrete october 1989 6 performing organization code 7 author^) 8 performing organization.
Definition “roller-compacted concrete (rcc) is a no-slump concrete that is compacted by vibratory rollers” • zero slump (consistency of damp gravel. 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 paver and the steel drum and rubber-tire rollers. 3 understand what roller compacted concrete (rcc) pavement is learn the principal differences between asphalt, conventional concrete and rcc pavements understand how rcc pavement is designed and constructed understand the types of applications best suited to rcc through presentation of examples in texas and the us. The german company powtec maschinen und engineering gmbh presents a completely new generation of roller compactors which converts powder into granules the innovative roller compactor type rcc. Roller compacted concrete pavements (rcc) 152301 description this supplement outlines the requirements for production and construction of roller.
On completion of a length of ge-rcc, roller compaction of the rcc with the large vibrating rollers should take place up to the treated zone, and beyond if the formwork will permit, so that the contact between the two is fully compacted. Roller compacted concrete (rcc) is a high strength paving material rcc is placed like asphalt and is stronger than conventional concrete additionally, rcc has a consistent and competitive price since all of its raw materials are locally manufactured. Roller compacted concrete mix proportioning method i of making roller compacted concrete: uses the principles of soil compaction to produce a lean rcc, where the optimum water content of the concrete is the one that produces the maximum dry density of the mixture. What is rcc definition “roller-compacted concrete (rcc) is a no-slump concrete that is compacted by high density pavers and vibratory rollers.

This page provides typical material properties of roller-compacted concrete (rcc) as reported by the national concrete pavement technology center's guide for roller-compacted concrete pavements. The rcc can be laid with a standard asphalt paver, but then it requires more rolling to get it to the required compaction savko prefers to lay rcc with an abg titan paver with a dual tamping screed that can achieve compaction of nearly 90% right out of the paver (vogele also makes a high-density paver.
The soil compaction method is the most widely used mixture proportioning method for roller compacted concrete pavements this proportioning method involves establishing a relationship between the density and moisture content of an roller compacted concrete mixture to obtain the maximum density by compacting samples over a range of moisture. We are seeing more news surrounding one of the more exciting innovations in the concrete industry: roller-compacted concrete (rcc) as evidence, astm international is formalizing a method for making a cylindrical specimen of rcc in a gyratory compactor.
