Residential streets are intended to provide access to adjacent residential
properties. They are designed for low speed, low traffic volume and
relatively light loadings.

Assumed Traffic
Low speed, low traffic volume and relatively light loadings. Truck traffic
is limited to those vehicles that provide residential services such as garbage
trucks, delivery trucks and the occasional moving van.
Design Considerations
If buses (school or public transit) use or are anticipated to use the
residential street on a regular basis the street should be designed using
an
approved design procedure.
Construction Considerations
If the residential street is fully paved before the surrounding homes are built,
the pavement may be damaged by heavy construction traffic such as loaded dump
trucks, material delivery vehicles and construction equipment. In most
cases it is advantageous to pave a residential street in two stages.
First, before home construction beings a layer of
ATB (in accordance with
site paving thicknesses) creates a paved street that
allows construction vehicles to access the site without tracking mud or damaging
the subgrade. It also
allows potential buyers the opportunity to see their homes in a cleaner
environment. Second, when major portions of the project are ready for
occupancy, the ATB layer can be repaired if needed and a final lift of
Class A,
Class B or
Modified Class B
(Commercial Mix) can then be placed as a
surface course.
