Course Description
This course outlines pavement design of roads. All three accepted methods of pavement design are covered, including Soil Factor, R-value thickness, and an introduction to MnPAVE for thickness design. design guide will be used to review the importance of and tools for the following elements of roadway design: data collection and accurate traffic projections; subgrade soil evaluation and best practices for enhancements; pavement section materials and specifications; and best construction practices and their effect on pavement life.
