Repair of Rutting Caused by Studded Tires

摘要

Rutting caused by studded tire wear has become a major issue in Oregon because of the impact on the infrastructure and the increase in driving hazards. It is estimated that the cost to mitigate the damage from studded tire use in 1993 alone is $42 million state-wide. The ruts caused by the studs lead to reduced pavement life which increases the life cycle costs. The safety hazards include an increase in splash and spray and hydroplaning during rainy weather. Several alternatives were identified to repair the ruts caused by studded tires. The alternatives include: microsurfacing, stone mastic asphalt (SMA), NOVACHIP(R), thin overlays, conventional overlays, roller compacted concrete, ultrathin concrete overlays, fine tooth milling, diamond grinding, hydroblasting with a bonded inlay, and realigning travel lanes.
