Introduction to Geotechnical Issues in Pavement Design
This online engineering PDH course introduces geotechnical issues in pavement design, construction, and performance, including: 1) the identification of the geotechnical parameters of interest; 2) the influence of climate, moisture, and drainage; 3) the impact of unsuitable subgrades; 4) the determination of the geotechnical inputs needed for designing different types of pavements; and 5) the evaluation and selection of appropriate remediation measures for unsuitable pavement subgrades. A brief history of the AASHTO highway pavement design techniques is included to illustrate how geotechnical design considerations have grown in importance and prominence over time. In addition, the mechanistic-empirical design approach developed under the NCHRP 1-37A Pavement Guide is discussed.
This 7 PDH online course is intended primarily for civil, geotechnical, highway, and transportation engineers interested in gaining a better understanding of pavement design.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the historical perspective on pavement design
- Learning about the components of a pavement system
- Learning about flexible, rigid, and composite pavements
- Learning about unpaved and naturally surfaced roads
- Understanding pavement performance with ties to geotechnical issues
- Understanding the issues related to new construction, rehabilitation and reconstruction
- Understanding the design considerations related to natural subgrade, cut and fill, environmental effects, drainage, and soil improvement
- Understanding the sensitivity of pavement design to geotechnical parameters
- Learning about empirical, mechanistic and mechanistic-empirical design
- Familiarizing with the AASHTO pavement design guides
- Familiarizing with the NCHRP 1-37A Pavement Guide
In this professional engineering CEU course, you need to review Chapters 1, 2 and 3 of the FHWA publication "Geotechnical Aspects of Pavements", FHWA NHI-05-037, by B. Christopher, C. Schwartz, and R. Boudreau, May, 2006.
