Collector Streets

Collector streets connect the residential streets with arterial routes. They may have significant truck and bus traffic and their closure for paving could create substantial commuter delays.  Collector street designs can often be applied to rural roads as well.

Assumed Traffic
Low to intermediate speed, moderate traffic volume and some heavy loadings. Truck traffic can often include substantial amounts of delivery vehicles, school buses and, sometimes, public transit buses.

Design Considerations
Collector street traffic loading can vary widely. High traffic streets (specifically those with substantially higher heavy truck and bus traffic levels than those listed above) should be designed using an approved structural design procedure.

Construction Considerations
Consideration should be given to paving in two separate lifts to allow street use with only minimal delays during construction. Any localized failures in the first lift can be repaired before final lift placement.
