Heavy Vehicles vs. Urban Pavements

Description:

An analysis was conducted of the impact that overweight vehicles have and will have on the life of the pavements in the Seattle metropolitan area. The study focuses on major Metro bus routes with both rigid and flexible pavements.

Recommendations are made to mitigate the impact of the higher loads from the bus fleet. These recommendations include route modifications to avoid streets with thinner, underdesigned pavements, increasing pavement thickness for rebuild or overlaid streets, and the purchase of vehicles which meet legal axle loads.
