RE: Cost saving considerations for Sandy Lake Road.
Dear Ken:
As we discussed dudng our recent phone conversation I believe that there are
some very real opportunities to save the City of Coppell money while constructing a
read made of the Highest Quality Paving Materials.
This opportunity may be unique to Coppell due to the potential people involved
and the location of their facilities and equipment. One of the items we discussed is
Cement Treated Base (Plant Mix). I would like to propose utilizing Cement Treated
Base due to it's supedor load carrying ability when compared to other base materials
including Lime Stabilization. The advantages of Cement Treated Base are many, and
it is because of these advantages that the Dallas North Tollway, D/FVV Airport, Alliance
Airport, City of Carrollton and the City of Grapevine all utilize Cement Treated Base just
to name a few.
Over the past few years we have adopted a plan to utilize recycled Asphalt
Paving (RAP) as part of our raw matedal use for Cement Treated Base. Dudng this
time we have produced a high quality mix utilized throughout the metroplex on many
projects. Recently I have had some discussions with Mr. Mike Sharp with Dallas
County. Currently we are purchasing RAP matedal from Dallas County, this matedal is
milled up with the Milling Machine that Dallas County currently utilizes throughout
Distdct One in working with the vadous cities within the district.
Currently Mike Sharp and his crew ar~ scheduled to perform the excavation and
grade work on Sandy Lake from 1-35 to Ma~Irther Road. Dallas County is also
experienced in the application and lay down process for Cement Treated Base. Mike is
interested in looking into Dallas County possibly doing the excavation and laydown of
Cement Treated Base on this section of Sandy Lake in Coppell. Part of the cost
savings Coppell will realize is not only in Dallas County participating but in the ability to
recycle the existing asphalt paving, run it through our Cement Treated Base plant on
Beltline Road, which will remix it with cement as a high quality base with a strength of
400 PSI in 7 days. As a truck bdngs in RAP Matedal it will leave with Cement Treated
Base, this will reduce freight cost significantly and result in additional savings to the
C~ty.
I suggest we set up a meeting as soon as possible to discuss these possible
ways of saving the City of Coppell funds by having Dallas County participate in this
project. Mike Sharp is ready to discuss this possibility any time at your convenience.
Please contact me if you have any questions.
Sincerely,
Steve Bond
General Manager CTB
