RCC FOR PAVEMENT PROJECTS THE FUTURE OF PAVING WHAT IS RCC? The basic ingredients are the same as conventional concrete: sand, aggregates, cement, and water.

However, the quantities are different. RCC requires lower amounts of cementitious materials than traditional concrete, allowing for lower material costs, greater durability, and lower overall maintenance cost. Our RCC mix is commonly produced using a twin shaft mobile concrete batch plant capable of thoroughly mixing zero slump concrete in high volumes.

WHAT IT’S NOT… Today’s RCC is nothing like the past rough, unfinished and inconsistent. RCC today is economical and can even be broom finished and, in most cases, can look even better than conventional concrete at a fraction of the cost.

HIGH STRENGTH & DURABILITY PROVEN PERFORMANCE

PERFORMANCE PROVEN BY QC. RCC is a tough, strong, and durable product. When combined with a properly prepared sub-grade, RCC will perform at or above levels of conventional concrete.

A LOW COST HIGHER VALUE ALTERNATIVE TO CONVENTIONAL PAVING. Proper consolidation, or in this case, density, is critical for strength and durability. Because compaction is so critical real time Quality Control (QC) plays a large role in the placement of RCC. At Andale Construction we use a combination of internal and external QC to ensure the highest quality possible.

QC tests perfomed before, during and after placement include: Proctor Test for maximum wet density On-site Nuclear Gauge tests for moisture content.

A FRESH ALTERNATIVE TO TO TODAY’S PAVING NEEDS HOW OUR RCC IS DIFFERENT? The major differences in construction is that our RCC has a longer workable period and requires less compactive effort. Another distinct difference is that we do not finish the surface with a roller. Instead we use a trowel machine to make the surface more uniform, consistent, and durable. Using our patented finishing process, along with the ACEiT admix and finishing aid, we can now construct a textured surface on the pavement that is indistinguishable from conventional concrete.

HOW DURABLE IS RCC? In 2015 The University of North Carolina-Charlotte perfomed testing ASTM C-944. The tests verified ACEiT and troweling had positive affects on the surface of the pavement. RCC with the ACEiT additive increases the surface durability and resists abrasion by a factor of over 200%, and is comparable or better than conventional concrete mixes.

Andale Construction has overcome the biggest drawback of standard RCC it’s appearance.

Normal RCC which is it’s appearance similar to asphalt. However, with our finish process, we are able to make RCC look like conventional concrete with a broom finish or other textured finish setting us apart from any other RCC contractor in the world.
