Low-Volume Roads Engineering
Credits: 8 PDH
PDH Course Description:
This course presents an overview of the key planning, location, design, construction, and maintenance aspects of low-volume roads—defined as roads with an average daily traffic of less than 400 vehicles per day—that can cause adverse environmental impacts
and lists Best Management Practices to prevent those impacts.
The course addresses most basic roads issues in broad general terms, leaving narrow technical issues to the specialist. Included are key “DO’s” (Recommended Practices) and “DON’Ts” (Practices to Avoid) in low volume roads activities, along with basic
design information. These fundamental practices apply to roads worldwide and for a wide range of road uses and standards.
