City of Roseville, 2018 Roller Compacted Concrete Project

Twining developed and peer reviewed technical specifications (special provisions) for construction of various types of concrete pavements, for both city streets and highways. Our team will be implementing this paving technique to a number of residential streets in Roseville including Washington Boulevard, Pleasant Grove, and Westpark Phase 4.

Roller Compacted Concrete (RCC) was developed in the 1970s as an affordable pavement solution that would stand up to high volumes of heavy loads while resisting freeze-thaw damage. Because it’s a drier mix than traditional concrete, RCC is quickly installed with high-density asphalt paving equipment and compacted using vibratory rollers – without forms, rebar or extensive finishing. You simply mix it, place it, compact it and cure it. RCC minimizes construction costs. And keeps traffic flowing, typically within 24 hours.

Twining has provided quality control and engineering support services for more than 300 Caltrans concrete pavement projects, including: (i) new construction and widening: jointed plain concrete pavements, continuously reinforced concrete pavements, roller compacted concrete (shoulders); and (ii) pavement rehabilitation and preservation: various pavement preservation and rehabilitation projects utilizing rapid strength concrete, and pavement preservation and rehabilitation projects utilizing precast panel systems.
