The Village of Streamwood is in its fourth year of rebuilding residential streets with roller-compacted concrete (RCC) using its own crews and equipment. Long used to build dams and low-speed, heavy-duty pavements, Top-notch team effort, RCC is a zero-slump base that can be placed with a standard asphalt paver and overlaid with asphalt within 24 hours. With so little water, the mix behaves a lot like – although not exactly the same as – asphalt during placement.
