For more than two decades, DRS LTD
has been operating as a wholesale asphalt manufacturer and supplier to
many municipalities as well as local paving contractors. Regularly
serving the Madison area and its surrounding communities, our
plant is located at 7154 Highway 14 Middleton, WI (1 mile west of the
Beltline).
ASPHALT
COMPOSITION:
The finished texture of
asphalt is directly related to the composition of its mixture. DRS assures
quality and consistent mixtures because of our computerized asphalt
batching system. This system allows us to electronically control the
amount of each element that is used to make specialized mixes for
specific projects. It has also allowed us to produce performance cold
mix, regular, porous, and
our patented rubberized asphalt mixtures. The main comparison between
different mix designs relates to the varying quantities of sand and
stone. A mixture with a high sand content will appear very uniform,
having few if any large rocks showing. While this may be
visually appealing, the larger rocks are necessary for a stable mix.
REGULAR MIX:
Many people think all asphalt is the same.
Regular hot asphalt mixes generally consist of assorted stone sizes,
sand, liquid asphalt and a few other small elements. On our
contract we will refer to "regular" hot asphalt; which simply means
there is no special additives, unique features, or adjusted stone
size. Our 'regular' mix mainly comprised of virgin materials, which is
a higher quality grade than those that are made with large amount of
recycled asphalt.
RUBBERIZED MIX:
We are proud to call
ourselves a leader in our industry with the capability to manufacture
a US patented asphalt mix. Rubberized asphalt simply takes our
'regular mix' and adds a combination
of recycled rubber
and polyester fibers. This mix has proven to be much more durable in
withstanding our harsh Wisconsin winters. We are so confident in this
long lasting asphalt mix, that we offer a three-year warranty against
asphalt failure, versus a one year warranty on our regular asphalt
mix. A few of the major advantages of Rubberized Asphalt include:
-
More flex and
durability (with respect to the freeze/thaw cycle)
-
Three year warranty
-
Less susceptible to
cracking
-
Environmentally
friendly (recycles old tires)
-
Adheres better to
previous surface (especially on overlays)
BINDER MIX:
This mix is generally only used on larger
project where 2 separate layers of hot asphalt would be applied. The
'binder' mix has a very similar composition to a 'regular' mix, but
has less liquid asphalt and potentially more recycled asphalt grounds.
This mixture generally has less durability as a surface product and is
only used if a layer of a 'regular' our 'rubberized' mix will be paved
over it.
POROUS MIX:
This is another hot mixture, but it is
produced with little to no sand of fine material in the mix. When
paved over a specially design base material, a 'porous' mixture will
have many open voids on the surface and throughout the mix.
Instead of rain
water traveling along the surface to a designated drainage area;
water can pass through the surface
to a recharge bed of coarse stone, & will enters the ground
naturally.
COLD MIX:
This mix is designed to be used for
patching purposes, when hot-mix asphalt is unavailable or not the
best solution. This mixture can be used at any time during the
year, however more commonly used during the winter months when our
plant is shut down. The durability is typical weaker than hot
mix, but generally more expensive when it comes to material costs.
