An Introduction to Road Design for Cold Regions
This online engineering PDH course discusses roadway and runway design considerations for arctic and subarctic regions. It will introduce you to the design of subgrades, base courses and flexible and rigid pavements in these cold regions.
The construction of satisfactory roads and airfield runways in seasonal frost and permafrost areas is normally more difficult than in temperate regions because the imperviousness of the underlying permafrost tends to produce poor soil drainage conditions, and because disturbance of the natural surface may set in motion adjustments in thermal regime, drainage, and slope stability which may have serious and progressive consequences.
This 2 PDH online course is intended for civil and geotechnical engineers and other design and construction professionals seeking an introduction to materials and methods for design of roads and airfield runways in arctic and subarctic regions.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Learning about the soils where there is danger of loss in bearing capacity upon thawing, and of heaving action upon freezing
- Understanding the four classifications of soils in which ice segregation generally occurs when favorable ground water and freezing temperatures are present
- Learning how frost and permafrost conditions may be altered by changed surface conditions produced by construction
- Understanding how in areas of permafrost the location of the ground water surface is greatly influenced by the existence of the underlying impervious permafrost layer
- Making recommendations for base course and pavement composition in arctic and subarctic regions
- Learning about base course design in non-frost-susceptible soils
