Chip sealing is a process used to preserve and treat asphalt roads with a liquid asphalt oil and water mixture covered by crushed stone. It provides a new roadway surface and helps to prevent pavement deterioration. Application at the right time can extend the life of a roadway surface for about three to five years.
After years of traffic and winter freeze-thaw cycles, small cracks develop in roadway pavement. If left untreated, moisture seeps into these cracks and eventually forms potholes when the water freezes and expands. As the name implies, a chip seal treatment seals such cracks and thus helps to prevent potholes from developing. It also provides a waterproof membrane and improves traction.
Chip sealing is an important component of JCDOT’s pavement preservation program. Roads are selected each year based on surface type, condition, age, traffic volume, safety factors, and the availability of funding. The American Association of State Highway and Transportation Officials (AASHTO) reports that for every dollar invested in extending roadway life through pavement preservation, $6 to $14 is saved in future roadway rehabilitation and construction costs.
JCDOT makes every effort to reduce vehicle damage during and immediately after chip seal projects, including the posting of reduced speeds in work zones; closing roadways or lanes during chip seal projects; and sweeping the roadway after project completion to eliminate loose stones. Motorists can help protect their vehicles when driving through chip seal project areas in the following ways:
- Use alternate routes
- Slow down. High speeds can cause loose stones to scatter and damage vehicle paint and windshields.
- Increase distance between vehicles. Leave space between you and other vehicles to reduce damage caused by loose stones.
- Follow posted work zone signage, use caution and consider worker safety when traveling through a work zone.
Green Lights on Maintenance Vehicles
To improve the safety of our drivers and motorists, Jackson County Department of Transportation has joined other municipal transportation agencies in installing green strobe lights on our maintenance vehicles. Most of our vehicles will use a combination of amber and green lights, which will differentiate them from other emergency and service vehicles.
According to JCDOT Managing Director Christopher Bolt, “The flashing light patterns you will see are very distinctive and are clearly not traffic signals. Green is one of the most visible colors to our eyes at night. Green LEDs are very visible over a long distance, effectively cutting through fog, snow, and rain. Other states have been experimenting with these with positive impacts on visibility, and the overall safety of maintenance workers and equipment. The Jackson County Department of Transportation is a leader in safety initiatives like this, and you will soon see these green lights statewide.”
