Abstract:It is common for local street and road pavements to be constructed using
portland cement concrete (PCC) directly supported on natural subgrade
without considering subgrade treatment or structural support layers such
as granular subbase. In order to optimize the performance of concrete
pavement, it is critical to understand how the support layers can be
designed and constructed to provide the most economical life cycle cost
of the pavement system and minimize public funds expenditures on local
roads.
