Subbase (pavement) - Wikipedia

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.

fixed carbon content of sub-bituminous coal ranges between 46% and 60% and has a heating value of 8300–13,000 Btu/lb. Typically, sub-bituminous coal contains less sulfur, resulting in 'cleaner' burning. Higher-ranked coals (bituminous coal, anthracite) are generally harder and stronger, and often have a black vitreous lustre.
