How often are roads covered with chip seals?
In an average year, chips seals are applied to about 6 percent of Josephine County’s total of 570 miles of county-maintained roads. It is only through the periodic use of chip seals that the Public Works Division can prolong the life of an asphalt road and avoid the higher cost of an overlay. The work typically takes place in the summer. The warmer weather is necessary for the asphalt to cure properly and take a firm grip on the rock chips.
