At JLS, we care about
our environment, our mountains, and our trees. Asphalt concrete is
often touted as being 100% recyclable. Asphalt concrete that is
removed from a paved surface is usually stockpiled for
later use as a base course material. This reclaimed material,
commonly known by the acronym RAP for "recycled or reclaimed asphalt
pavement," is crushed to a consistent gradation and added back to
the mixing process. Very little asphalt concrete is actually
disposed of in landfills.
Cold mix asphalt concrete
is produced by emulsifying the asphalt in water with (essentially)
soap prior to mixing with the aggregate. While in its emulsified
state, the asphalt is less viscous and the mixture is easy to work
with and compact. The emulsion will break after enough water
evaporates and the cold mix will, ideally, take on the properties of
cold HMAC. Cold mix is commonly used as a patching material and on
lesser-trafficked service roads and walking paths, such as the one
below that JLS Company surfaced along the French Broad River in
Asheville, NC. The tubing activities were happening at the
same time JLS was surfacing the walkways.
