In these days of high asphalt costs, contractors are very concerned about asphalt yield. Especially if they’re paid by the square yard, they don’t want to lay the mat extra thick just to be extra-sure they meet the spec.

That’s what they believe at the Allan A. Myers Civil Division of American Infrastructure – and they did something about it. They purchased a Millimeter GPS™ system from Topcon, and they figure it will pay for itself in reduced asphalt waste in a year and a half.

“The Millimeter GPS controls the elevation of the uncompacted mat and gives us assurance that we’re maintaining a consistent mat thickness during high production paving,” says Scott J. Styfco, Myers’ roadway manager for the five-mile asphalt paving project on the Pennsylvania Turnpike. “All of our blacktop is paid for in square yards, so if we lay it too thick, it comes out of our pocket.”

Under a $168-million contract, Myers is widening the stretch of Interstate 276 to six lanes from four. Last year, without a Millimeter GPS system attached to the paver, Myers paved the outside shoulders and slow lanes on both sides of the highway.
