PTC Mine Grout
As part of the third lane expansion of the Pennsylvania Turnpike from MP 67.59-MP 74.59, Brayman performed 30,000-ft of drilling and onsite batching of 16,000-cy of grout to stabilize an abandoned coal mine adjacent to the roadway. Utilizing an Elkins (now Cemen Tech) volumetric batch plant, a flyash/cement/sand mixture was batched and subsequently pumped 1,500-ft away to grout injection holes, eliminating the need to transport grout with ready-mix trucks.
