Starting at the end of July, four downtown Boise streets will be microsealed:
Microseal is a mixture of a polymer modified asphalt emulsion and well-graded aggregates that are placed by a mobile mixing machine. This mixture will seal out the harmful effects of water, UV rays, and oils, protecting and extending the life of the asphalt. Microseal aids in resisting traffic abrasion, fills in voids in the asphalt, and helps to improve traction.
The microseal is quick-setting, and can be applied at night. Traffic may return to a freshly microsealed road in an hour.
