Low Volume Roads Chapter 8 – Culvert Use, Installation, and Sizing

Course Synopsis:

Low Volume Roads (LVR’s) are normally considered as roads with relatively low use, an Average Daily Traffic (ADT) of less than 400 vehicles per day, design speeds typically less than 50 mph, and corresponding geometry.  Most roads in rural areas are low-volume roads.

Understanding the engineering principles and practices uniquely applicable to the design, construction, and maintenance of Low Volume Roads allows the engineer to determine and implement the Best Management Practices described herein.  This course provides specific information and engineering criteria regarding culverts and their use, installation, and sizing for Low Volume Roads.
