Abstract: There is a need for cost-effective surfacings for areas subjected to tracked-vehicle traffic to reduce maintenance costs and improve safety. Surveys of several locations with tracked-vehicle traffic were made to observe pavement conditions and maintenance requirements. These observations demonstrated that pavement performance depended on how local personnel perceived their problems and local repair methods. A test section to evaluate several mixtures was constructed and tested at Fort Stewart, Georgia. The items tested were these : (a.) Fiber-reinforced concrete. (b.) Wire-mesh-reinforced concrete. (c.) Roller-compacted concrete pavement (RCCP) in depths from 4 to 10 in. (d.) Concrete paving blocks over sand-grid base. (e.) Latex-modified asphaltic concrete. (f.) Steel-slag asphaltic concrete. (g.) State of Georgia standard E-Mix asphaltic concrete. The properties of the various items before and after construction were determined and evaluated. Trafficking on the test section consisted of normal traffic with M60A-1 tank and M-88 tank retriever traffic in addition to minor car and light truck traffic. Locked-track turns were performed on each item, and the pavement surface was evaluated. Results of this study indicated that all items tested provided a satisfactory surface when properly prepared. RCCP provides a suitable surface for roads and parking areas at favorable costs compared to conventional concrete. Paving blocks provide a suitable surface and the ability to remove and replace or relevel individual blocks can offset their high-cost, labor-intensive installation. The asphalt pavements evaluated, while not as resistant to abrasion as concrete pavements, are less expensive to construct and repair.
