Pageland Dragstrip is a well known 1/8 mile drag racing venue in South Carolina, serving local racers and motorsport enthusiasts with regular bracket racing, test and tune events and community race days. Its long standing presence in the local motorsport community has made it an important fixture for drivers seeking a reliable and well maintained racing surface.

Pageland Dragstrip needed a durable replacement for a deteriorating asphalt surface that had developed cracking and groundwater seepage. To improve long term performance, the asphalt from the burnout box to the timing boards was removed and rebuilt in concrete.

An 800-yard, 6-inch thick concrete slab was placed using a 4000 psi mix with 5–6% air, 5” slump, and 3 lbs/cy of BarChip MQ58 macro synthetic fiber. The fiber was added at the wash rack and mixed thoroughly with no clumping or balling observed during placement.

Concrete was placed directly from the tailgate onto the slab area. Aside from dowel baskets at control joints and a small rebar mat in the burnout box to accommodate additional pressure from the force of spinning tires, no conventional steel reinforcement was required. A light pan/power-troweled finish was applied, with fibers settling below the surface to deliver a clean, fiber free finish.
