Hammaker East Extends Road Life for US 64 with FiberMat®

Fayetteville, PA (May 2014) – Hammaker East, the leader in proprietary paving solutions, processes and machinery, announced a recently completed project – US 64 in Nashville, Nash County, North Carolina – is the longest stretch of road in North Carolina treated with FiberMat® technology. The approximate eight-mile stretch of roadway joins the town of Nashville to US 98. FiberMat extends the life of the road by absorbing traffic stress and delaying cracking.

The US 64 Nash County project represents both the longest roadway in North Carolina, and the company’s history using FiberMat technology. “FiberMat is a great alternative to traditional resurfacing methods, especially when the original roadway is concrete,” said Sid Witmer, director of sales and marketing for Hammaker East. “Essentially, FiberMat creates a bonding membrane of layers of oil, chopped glass fibers and more oil which is applied to the cracks. Then, we add a hot mix that absorbs the oil and keeps the reflective cracks from returning thanks to the fiber barrier,” explains Witmer. FiberMat delays crack propagation by dissipating traffic stresses horizontally through the fibers rather than vertically through the wearing course. The application is quick, providing traffic-ready roads within 30 minutes.

“No one wants to resurface a road they know will experience cracking within 12 – 24 months,” explained Matt Johnson, president of Russell Standard/Hammaker East. “FiberMat delays cracking for years, which eliminates the cost of remobilizing road construction crews and investing in more materials for at least one to three additional times, which ultimately delivers a long-term cost savings.”

The US 64 Nash County project used the Type B, SAMI (Stress Absorbing Membrane Interlayer) FiberMat installation system that serves as an intermediate layer between the existing pavement and a new wearing course overlay. Additionally, the project included testing a stretch of un-milled roadway treated with FiberMat.

A combination of polymer-modified asphalt emulsions, proprietary fiber strands and aggregate, FiberMat creates a surface membrane. This membrane bonds well to concrete and asphalt, and absorbs traffic stresses in the pavement structure, forming a waterproofing barrier that impedes the ingress of water into a road. The technology reduces, repairs and resists reflective surface cracking; increases tensile strength and flexibility of the road surface; and rejuvenates wearing road suffering from top-down cracking.

Road repair on US 64 was completed Friday, May 9, 2014.
