ROLLER COMPACTED CONCRETE
WHAT IS RCC? Roller-Compacted Concrete (RCC) uses the same basic ingredients as conventional concrete: sand, rock, cement, and water, in a dense, zero-slump mix. RCC pavements require no rebar or forms, which reduces construction time and simplifies installation. Our broom finish gives the surface the familiar look of conventional concrete while delivering a strong, durable pavement for heavy loads and demanding applications.

THE RCC DIFFERENCE A CLOSER LOOK AT RCC
RCC and conventional concrete share the same basic ingredients, but their proportions and placement methods create different internal structures. The illustrations below show how RCC combines dense aggregate packing with cement bonding to build strength. Fig. 1A Conventional Concrete
CONVENTIONAL CONCRETE
Conventional concrete uses a workable mixture of aggregate and cement paste. As it hardens, the paste surrounds and bonds the aggregate, creating a strong, solid pavement.
RCC PAVING RCC combines a tightly packed aggregate structure with a lower-paste, zero-slump mix. Compaction brings particles closer together, reduces voids, and promotes aggregate interlock, while cement paste bonds the mixture into a strong, durable pavement. Fig. 1B RCC
PROPER MIX DESIGN, COMPACTION, AND CURING HELP RCC DELIVER LASTING PERFORMANCE IN DEMANDING CONDITIONS.

CONVENTIONAL CONCRETE
TRADITIONAL RCC
OUR RCC
WHAT MAKE RCC DIFFERENT Our RCC combines a dense, compacted concrete structure with admixtures that extend workability and a finishing process that delivers the familiar appearance of conventional concrete. Today’s RCC is stronger, more durable, and easier to install, all while maintaining the aesthetic look of our broom finish.
MORE TIME FOR PLACEMENT AND FINISHING
Our admixtures extend the workable period compared with traditional RCC, giving crews more time to place, compact, and finish the pavement.
REDUCED COMPACTION EFFORT Our mix requires less compaction effort than traditional RCC while achieving the specified density.
A MORE UNIFORM SURFACE After compaction, we power-trowel the surface for a more consistent finish, then apply a broom texture to mimic conventional concrete.
HOW IS RCC MADE FROM MIX TO FINISHED PAVEMENT See our RCC process in action, from controlled mixing and placement to compaction, power troweling, and broom finishing. Each step combines RCC's dense structure with the familiar finished look of conventional concrete. NO REBAR • NO FORMS • CONVENTIONAL BROOM FINISH
