Introduction
The information will be included in the pavement design report. This section
discusses the major requirements critical to a pavement design:
• traffic loads
• serviceability index
• material characterization
1. Traffic Loads
One of the primary functions of a pavement is load distribution.. Loads, the vehicle
forces exerted on the pavement (e.g., by trucks, heavy machinery, airplanes), can
be characterized by the following parameters:
• tire loads
• axle and tire configurations
• typical axle load limits
• repetitions of axle loads
• traffic distribution (by direction and lane)
• traffic projections.
