PRS Replaces Aging Asphalt at Bear Creek
Posted on Sep 08 2009 at 11:38 AM
Located in the Temecula Valley, Bear Creek is home to luxury homes and one of the
most prestigious golf courses in Southern California. Built in 1983, this opulent
community needed to replace their aging asphalt roads. Estimates were sought for
the conventional methods of construction but these exceeded the H.O.A.'s budget
estimates.
Darrell Durham, the owner of General Paving enlisted the assistance of Pavement
Recycling Sytems to "value engineer" the project and make it possible to achieve
the community's goals.
The cost prohibitive, conventional method of construction, called for grinding,
loading and hauling away 3" of existing asphalt and importing 3" of new hot mix
asphalt to be paved back.
PRS recommended an environmentally and economically sounder solution in the form
of Cold In Place Recycling (CIR). With the CIR process, PRS cold planed 3" of the
existing asphalt and instead of hauling it off site, crushed the material and mixed
it with a high-grade emulsion to produce a new asphalt out of it on site and in
place. This process can be done with a recycling train as it was done at Bear Creek,
or with a portable plant for parking lots or areas inaccessible to the recycling
train. With the recycling train you literally see the old asphalt disappear and
be replaced by new asphalt ready to be paved right away in one smooth in-line process.
On the Bear Creek project CIR was done on the upper 3" of existing asphalt and then
capped with a 0.10 foot conventional hot mix overlay to increase the overall structural
section of the roadway.
Besides being more cost effective, the CIR process was environmentally sounder because
it eliminated the numerous trucking and associated greenhouse gas emissions associated
with a conventional remove and replace type of construction; The CIR process also
took far less time to accomplish and was much less disruptive to the public and
traffic. The CIR process has the smallest carbon footprint of any rehabilitation
system available today, and is being increasingly specified out as the preferred
method by Cal Trans, the Federal Hwy. Admin. (FHA), municipal/county agencies, and
private entities. This "Green" recycling process is fast becoming the wave of the
future.
