RE: PUBLIC HEARING CONCERNING PAVEMENT TYPE SELECTION FOR COUNTY
ROAD 49 EXTENSION PROJECT
A public hearing was conducted on July 10, 2013, at 9:00 a.m., with the following present:
Commissioner William F. Garcia, Chair
Commissioner Douglas Rademacher, Pro-Tem
Commissioner Sean P. Conway
Commissioner Mike Freeman
Commissioner Barbara Kirkmeyer
Also present:
Acting Clerk to the Board, Susan Brown
Assistant County Attorney, Brad Yatabe
Public Works representative, Wayne Howard
The following business was transacted:
I hereby certify that pursuant to an electronic notice to industry representatives dated
July 1, 2013, a public hearing was conducted to consider pavement type selection for the
County Road 49 Extension Project. Brad Yatabe, Assistant County Attorney, made this a
matter of record.
Wayne Howard, Department of Public Works, gave a brief overview of the review process,
which was based on current information, new traffic counts, and a soil study of the entire 34
miles. He pointed out that the County Road (CR) 49 Extension project begins at 1-76 and ends
at CR 14, and noted the extreme increase in heavy truck traffic. Mr. Howard said that car
loadings do not play that much of a role when looking at highway design; however, truck loading
has recently climbed from 25 percent to 52 percent and cost has changed accordingly. He
presented a concrete and asphalt overview, noting rigid versus flexible, and interactions with
soil types and depth of pavement needed. He said concrete spreads the load out over weaker
soils, which most of this stretch has, and expounded upon on this subject. He presented a chart
showing the cost data on each type; explained the unit costs and the analysis; showed a cash
flow diagram showing initial cost, life cycle of the material, and potential expenditures over time
and explained how it was reached. In response to Commissioner Kirkmeyer, he confirmed the
diagram pertained only to material costs, not labor. He showed a material price index not
adjusted for inflation and reviewed the Pavement Life Cycle Cost Comparison Chart in detail.
He gave the total costs of materials for each selection for the entire corridor and gave a list of
advantages and disadvantages for each type of pavement.
Thomas Peterson, Colorado Asphalt Pavement Association Executive Director, on behalf
of its Weld County members, introduced asphalt pavement design and the mixtures used. He
stated that 90 percent of Weld County's roads are asphalt. He said an overlay can be added to
extend the life cycle, and, in response to Commissioner Rademacher, he confirmed that milling
happens prior to overlay. He spoke to the issue of cost analysis and estimation variations.
Mr. Peterson said mix and materials can be sent to CDOT for testing, looked at project costs in

terms of mobilization, and discussed alternate bidding, noting there are facilities within Weld
County. In response to Commissioner Kirkmeyer, he stated they would be using premium
asphalt which would change the time period in terms of rehabilitation (from year 10 to year 15)
and lower maintenance costs and answered questions about crack seal and other rehabilitation.
He asserted that staff's comparative analysis is flawed in this regard.
• Jerimy Runner, Martin Marietta Materials, spoke in regard to using Weld County
businesses for this project and said he has 78 employees in Weld County. Commissioner
Kirkmeyer noted they would still be able to bid on the aggregate materials if concrete is
selected.
• Ken Coulson, Coulson Excavating, a Weld County business, said he has 15 Weld County
employees and asked the Commissioners to allow alternate bidding. He said his company did
1-25, north to Highway 14, and would be using the same mixes. In response to Commissioner
Rademacher, he confirmed that project was asphalt over crushed concrete. In response to
Commissioner Kirkmeyer, he noted that they also constructed Highway 287 and explained the
mix used. Mr. Peterson noted two other Weld County asphalt companies may bid the project as
well.
La Jamie Johnson, P.E., Portland Cement Association, Rocky Mountain Regional Office,
introduced Gary Ungerman, of Castle Rock Construction, representing the American Concrete
Pavement Association, Ken Lawson, Lawson Construction, and Mark Johnson, Bestway
Concrete. Mr. Johnson said concrete will last 30 years, by design, but some roads have been
around for much longer, especially with some rehabilitation; he cited low inflation and listed the
corridors they have completed. He presented CDOT numbers, and addressed consistent
maintenance on each project, life cycle costs, and comparison. He asserted that a 15 -year
asphalt life is a very rare occurrence and said concrete is the pavement of choice on truck
routes in Colorado because heavier traffic results in more asphalt maintenance. He claimed
that concrete smoothness is improved and still improving. Mr. Johnson also noted the fixed unit
price of concrete reduces risk, whereas asphalt is affected by oil prices. He claimed that a life
of 40-50 years is possible. He then introduced companies which would like to bid. There was
discussion regarding the number of local employees and the alternate bidding process, as well
as cost per mile. In response to Commissioner Kirkmeyer, there was some discussion of longer
cure time for repairs (28 days initially then 12-24 hours).
El Mr. Howard returned, thanked both industries and said he had learned a great deal about
both products. He said Weld County primarily uses asphalt historically, but referenced long
term maintenance projections and inflation rate value. He said he believed that concrete lasts
better long-term for a roadway traveled by large and potentially over -loaded trucks and less
maintenance equals long-term taxpayer benefits.
El Chair Garcia opened the floor to public comment. Danny Kipp, Town of
Mayor, noted the number of trucks on this corridor is constantly increasing, and
staff's recommendation.

• Mike Bedell, Department of Public Works, spoke in regard to the alternate bid process,
noting it is used by CDOT and other counties, but there is a cost involved to produce
documents. He said, as a project manager, he fears that the department may write a bid
recommendation memo in the future for the preferred material, but that material may not be the
lowest bid, resulting in bid disputes. He requested a solid decision for one material or the other.
(Clerk's Note: 10:40, Commissioner Kirkmeyer left for 10 minutes during Mayor Kipp's and
Mr. Bedell's comments.)
• Bruce Barker confirmed the Board is not required to make an immediate decision. Chair
Garcia suggested that a motion be held in abeyance for Commissioner Kirkmeyer's return.
Commissioner Rademacher noted there are pros and cons for both, but due to the extreme
amount of truck traffic he supports concrete. Chair Garcia concurred. Commissioner Freeman
noted the complexity of an analysis like this and concurred that concrete is the best choice.
Commissioner Kirkmeyer asked about alternate bidding, upon her return, and Commissioner
Conway reviewed Mr. Bedell's testimony on the cost of the design fees, and the potential for
companies to dispute bid selections.
• Don Warden, Director of Budget and Management Analysis, in response to Commissioner
Kirkmeyer, said in his judgment he also leans towards concrete and is most impressed with the
potential for concrete to last beyond the 30 year life cycle. Commissioner Conway said there
were work sessions and extensive analysis of data and this was a fair and open process. He
noted the importance of this project in accommodating the County's expanding oil and gas
industry, pointing out that this material selection is project specific. Commissioner Kirkmeyer
concurred with Commissioner Conway's and Mr. Warden's comments and said the charter
requires looking at quality, quantity, and locality. Commissioner Kirkmeyer made a motion, after
considering the presentations from both industries, to approve staff's recommendation to
choose concrete as the preferred paving material for the County Road 49 Project and not
allowing an alternate bid process. Commissioner Rademacher seconded the motion, and it
carried unanimously.
