Plant Maintenance
A Turn Toward Repair
Concrete Pavement Preservation delivers on bumpy economic road.
All indicators are leading to a continued strong market in dowel bar retrofit, which involves reinforcing undoweled joints and cracks in highway pavement by inserting steel dowel bars in slots cut across the joint/crack.

An Efficiency Boost for this Asphalt Production Facility
Terex E225P asphalt plant at the heart of Grimes Asphalt efficiency moves.
In 2008, Grimes Asphalt purchased a Terex® E225P drum mix plant, which allowed the producer to move away from the start-and-stop asphalt production associated with the batch plant.

Innovative Porous Warm Mix Asphalt Minus the Fibers
Talley Construction uses a warm mix design that eliminates fibers from the porous asphalt on a parking lot project in Tennessee.
The asphalt was applied in two 4-inch lifts of AS binder containing 10% RAP. The layers were capped with 1.25 inches of Open Graded Friction Course (OGFC) surrounded by riprap.

A Look at Tomorrow's Asphalt Plant
A look at what an asphalt production facility might look like in 20 years
Asphalt production facilities of the future will most likely be enclosed in a building, which will keep plants 'out of sight' from neighbors and aggregates drier.
