Cass County Board: Chip sealing to be tested on Cass County State Aid Highway 1

PINE RIVER - Cass County will conduct a test over five years on a portion of County State Aid Highway 1 to determine whether chip sealing pavement helps preserve asphalt surfaces.

PINE RIVER - Cass County will conduct a test over five years on a portion of County State Aid Highway 1 to determine whether chip sealing pavement helps preserve asphalt surfaces.

The 6-mile CSAH 1 segment was paved this week. One mile will be chip sealed after one year and another mile each of the following five years. One mile will not be treated.

The Minnesota Department of Transportation will pay $10,000 each year, with the county paying $15,000 for each chip-seal treatment. Chip sealing involves spreading oil, then a layer of gravel over the paved surface. Traffic presses the gravel into the oil.

Cass County Engineer David Enblom informed the county board Tuesday MnDOT has shown through tests on high traffic state highways that chip sealing does prolong the life of pavement on those roads. This will be among the first tests on county highways to determine whether it also improves the life of lower traffic county highways.

It does improve traction on pavement and evens out surfaces where crack sealing has been done, Enblom said. The Cass test will help determine whether it also will prolong pavement life.

It will show how soon after initial paving that sealing is most effective and whether it is as effective on lower traffic roads as on high volume state highways, he explained.

Enblom reported the county has received a $717,787 federal grant through MnDOT to use epoxy painted edge striping rather than latex paint on several paved county roads in 2016 and to use ground-in, more reflective edge striping on additional county roads in 2017.

These fog line paint treatments will last twice to five times as long as regular latex paint, he said. Cass will pay a $79,753 match or 10 percent of the cost.

State-aid highways scheduled for the epoxy treatment are CSAHs 1, 4, 6, 7, 8, 9, 18, 22, 32, 33, 45, 58, 70 and 77.

Those scheduled for the ground-in paint treatment are CSAHS 2, 5, 7, 13, 36, 38, 44, 60, 75, 78 and County Road 105.

Enblom obtained board approval to purchase a larger skid steer loader immediately rather than wait for the one authorized earlier at a slightly lower price. The cheaper, smaller machine is not available for delivery for three months.

With the earlier delivery date, the larger machine will save the cost of renting a machine this summer, he said.

The board approved paying the city of Cass Lake $3,566 for a building permit for the new county highway garage being built there this summer.
