The Ins and Outs of RCC

During a water pipe rehabilitation, Chicago’s water district replaced asphalt pavement with RCC.


An easy way to tell if the moisture content is right is to squeeze a handful of mix.

When you open your hand, it barely clings together and almost nothing remains on your hand.

Placing 1-ft. RCC lifts from a conveyor onto the top of the dam, a bulldozer spreads the pile and rolling vibratory compactors densify the concrete while a track hoe consoldiates the edges.

Twenty Seven acres were paved for the new intermodal terminal. It took three to four minutes to place a semi load of RCC with a high-density paver. After a couple passes with a roller compactor the pavement density exceeded 98%.
