  • Subbase (pavement)

    In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. Subbase is often the main load bearing layer of the pavement.Its role is to spread the load evenly over the subgrade.
