(Victor Valley)– First District Supervisor Robert Lovingood praised county road crews for recent pavement upgrades along National Trails Highway.
“Having traveled this road for years, it’s great to drive on these newly re-surfaced stretches of old Route 66,” Lovingood said. “And I know residents of Silver Lakes, Helendale and Oro Grande appreciate the new sections of smooth road, too.”
The County of San Bernardino Department of Public Works completed a four-mile chip seal project on National Trails Highway in the Helendale/Oro Grande area in mid-November.
The chip seal was applied at two locations: a two- mile section north of Bryman Road to Rinaldi Street, and a two-mile section one mile north of Vista Road.
Throughout the County, chip seals are used as a protective coating for roads in good condition. It is the most cost effective treatment to preserve and protect the road surface from harmful oxidation from the sun and weather.
The County typically applies a chip seal to roadways two to three years after they have been resurfaced to protect the new resurface by sealing it and providing a wear surface. The concept is similar to applying a wood sealer to a wooden deck to extend the life.
The chip seal treatment is applied by County forces and the process involves spreading oil onto the roadway to seal it and applying gravel chips that provide a wearing surface. New procedures adopted by the County in the past few years included improved bonding, testing procedures, and the application of a “fog” seal upon completion of the chip application. This seal improves the bonding of the material to the roadway and improves appearance. The road is placed in our chip seal rotation program and the road will be evaluated for another chip seal approximately every 5 years.
