Loading Advanced : Soil Characteristics - PaveShare : A Segmental Paving Resource for Landscape Architects
In paving design, the subgrade is referencing the existing soil of the site. It is important to accurately assess the type of soil on a site as soil characteristics play a major role in the design of pavements. Soils that have a course grain and good drainage are generally stronger than fine grained soils with poor drainage. For example, a gravel soil with good drainage is significantly stronger than a clay soil with poor drainage. Coarse Gravel - Passes a 75-mm sieve (3-inch) and retained on a 19.0-...

It takes roughly 20,000 passes of the sedan to cause the same amount of same amount of damage as one pass of a tractor-trailer. In these scenarios, the design ESALs will be predetermined. This is usually based on the expected traffic mix. Reference ASCE and ICPI Tech Spec 4 to calculate the appropriate ESAL rating to a design. Other Lesson Components :. ICPI Tech Spec 4.
