RCC Placement Continues at Volkswagen Plant in Chattanooga.
May 10, 2010

Automakers have a love for roller-compacted concrete (RCC) pavements. Beginning with the General Motors Saturn Plant in Spring Hill, Tenn. constructed in 1988-1989, automakers have used RCC for its low cost, high construction speed, high strength and low maintenance in parking areas and access roads. Building on the success with Saturn, RCC pavements have been constructed for automobile manufacturing plants in Lincoln, Ala. (Honda), Vance, Ala. (Mercedes), Montgomery, Ala. (Hyundai), and LaGrange, Ga. (Kia). BMW joined the list last year by finishing over 200,000 square yards of RCC for an expansion at its Greer, S.C. plant. The latest to use RCC is Volkswagen at a plant in Chattanooga, Tenn. The plant is to produce a new mid-sized sedan sporting green technologies.

Placement of 4-inch and 8-inch RCC layers will continue until October of 2010. Over 500,000 square yards will be placed for use in parking areas and access roads for the plant itself and a training facility. Robert Smith, Inc. and Stein Construction are placing the RCC with high-density pavers. Both companies are Chattanooga-based and are experienced RCC contractors. The placement of the 4-inch RCC is the nation's first large scale placement of such a modest thickness. The subbase for the RCC will either be graded aggregate or a cement-stabilized soil depending on in-situ soil conditions. In addition to placement of RCC within the plant site, the access road into the facility (Enterprise Drive) used 9.0 inches of RCC with a 4.5 inch surface of asphalt. The RCC was placed by Highways, Inc. of Cookeville, Tennessee. All the RCC placed at Volkswagen will be produced by Sequatchie Concrete Service.

The use of RCC has definitely found a home with automakers for its low cost, high construction speed, high strength and low maintenance in parking areas and access roads. In addition, the white color of RCC also meets some LEED requirements due to the reduction of the "heat-island" effect.
