Pavement rehabilitation refers to making significant improvements to a pavement's condition and ride quality, resulting in a substantial extension of its service life. This enhancement can be achieved through structural or functional modifications. Conversely, pavement maintenance involves treatments aimed at preserving the condition, safety, and ride quality of the pavement, ultimately helping it reach its intended design life. Pavement engineers must possess a foundational understanding of pavement design and possess the ability to adapt designs to accommodate various constraints, such as curbs, gutters, utilities, and entrances for both private and commercial purposes, while also considering the requirements of the roadway. During this workshop, participants will gain a comprehensive understanding of pavement design and rehabilitation techniques applicable to flexible, rigid, roller-compacted concrete, and composite pavement structures. The workshop covers all three accepted methods of pavement design, including the Soil Factor, R-value thickness, and an introduction to MnPAVE for thickness design. Additionally, the workshop will utilize a design guide to emphasize the significance of various elements in roadway design, such as accurate data collection and traffic projections, evaluation of subgrade soil and recommended enhancements, selection of pavement materials and specifications, and best practices in construction that impact pavement longevity.

Course Objectives:
