It is common practice locally for contractors to take concrete and asphalt to one of the grinder facilities on the South Coast, have the materials ground up, and used as a recycled road base. The base is the sub-surface material, usually gravel and sand, that is compacted and becomes the surface on which the road asphalt is applied.

Monday morning the jack-hammer, technically a hydro-hammer, started to punch holes in the Embarcadero del Mar intersection asphalt in anticipation of the whole area being torn out this week. Other heavy equipment will pull up the pieces of concrete and asphalt and ship it off-site where it will be recycled.
