This video (.wmv format), recorded on 4/05/12, covers "All About Subbases and Subgrades".


The design and construction of an engineered roadbed (subgrades and subbases) is essential to the long-term performance and smoothness of concrete pavements. This video will cover the basics of subgrade and subbase design and construction, including basic terminology, and basic design principles and their impacts on pavement thickness, durability, and overall quality.


The program will emphasize proper selection and application of subbases and the appropriate consideration of subgrade variables for concrete pavements used for streets, roads, and highways. It emphasizes the major objective of obtaining long-lasting uniform support for a concrete pavement. Subgrade soil material classification and problems (expansion, heaving, etc.) are discussed in detail, along with many various options for stabilized and unstabilized subbases, and the materials of which they are composed. Multiple reasons for avoiding the use of permeable subbases (a.k.a. drainable or open-graded subbases) also are presented.
