following
Specifications
SUMMIT COUNTY GOVERNMENT
MEDICAL OFFICE BUILDING PARKING LOT
ASPHALT MILL AND OVERLAY
DESCRIPTION OF WORK
General
The Summit County Government is soliciting bids to complete an asphalt mill and overlay to the north parking lot and travel
lanes of the Medical Office Building. The owners have discovered that the existing parking lot and travel lanes are in need of
adequate asphalt maintenance to prolong the life of the asphalt. Items, materials, and equipment pertaining to this project
shall include the following:
A. Bonds
B. Measurements
C. Warm Mix Asphalt (WMA) Grade SX, PG58-28 (SX-75) Construction Requirements
D. Asphalt Millings
E. Pavement Markings
F. Add/Alt
G. Scheduling
H. Furnished Items
Location of Work
This project is located at the Medical Office Building 360 Peak One Blvd. Frisco, CO. 80443
Scope Details
The Contractor shall furnish all labor, equipment, materials, supplies, signage, traffic control and other incidentals
necessary to provide a 2” mill and 2” asphalt Overlay to the Medical Office Building parking lots and travel lanes,
while maintaining sufficient parking and access to the building during business hours. All asphalt work associated
with this project will conform to Warm Mix Asphalt (WMA) Grade SX, PG58-28 (SX-75) specifications and
construction requirements, as described below in section C of this document.
A. Bonds: This project will require the awarded contractor to provide pay and performance bonds for Summit County’s
asphalt Mill and Overlay project.
B. Measurements
1. An approximate Summit County GIS area calculation has been completed, showing an area of 8,783 square
yards for the combined travel lane and parking lot areas, proposed for Medical Office Building parking lots to
be bid for this project. As seen in the arial GIS map layout of project included in the RFP bid packet
2. The awarded Contractor for this project is responsible for field verification of these measurements, any
additional measurements, or suggested overage to complete bid.
C. Warm Mix Asphalt (WMA) Grade SX, PG58-28 (SX-75) Requirements:
Description
3|Page
This work consists of one or more courses of asphalt mixture constructed on a prepared foundation in accordance
with these specifications and the specific requirements of the type under contract, and in conformity with the
lines, grades, thicknesses, and typical cross sections shown on the plans or established.
References to sections and sub-sections in this bid item specification shall refer to the 2019 CDOT
Standard Specifications for Road and Bridge Construction.
Materials
Composition of Mixtures - The asphalt plant mix shall be composed of a mixture of aggregate, filler or additives
if required and approved, asphalt cement, and reclaimed material if permitted and used.
The Contractor shall submit a proposed warm mix asphalt mix design, including job-mix gradation, to the
Engineer. The weight of lime shall be included in the total weight of the material passing the 75 µm (No. 200)
sieve.
The job-mix formula for each mixture shall establish a single percentage of aggregate passing each required sieve
size, a single percentage of asphalt cement to be added to the aggregate, and a single temperature for the mixture
at the discharge point of the plant.
Mixtures Furnished to the Project - After the job-mix formula is established, all mixtures furnished for the
project shall conform thereto within the ranges of tolerances listed in the following Table 401-1
Table 403-1
1Tolerances for Warm Mix Asphalt
Asphalt Content

2Passing the 75 m (No. 200) sieve
± 2%
1 When 100% passing is designated, there shall be no tolerance. When 90 – 100%
passing is designated, 90% shall be the minimum; no tolerance shall be used.
2 These tolerances apply to the Contractor’s Process Control Testing.
The job-mix formula for each mixture shall be in effect unless modified in writing and submitted to the Engineer
for approval.
Should a change in sources of materials be made, a new job-mix formula shall be established before the
new material is used. This new job-mix formula shall be in effect until modified by the Engineer. Requests
made in writing by the Contractor for changes in the job-mix formula will be considered. The job-mix
formula may be changed by the Engineer if the change will produce a mixture of equal or better quality and
will:
(1) Permit better utilization of available material, or
(2) Result in a saving in cost to the Department through an
adjustment

CONSTRUCTION REQUIREMENTS
Weather Limitations and Placement Temperatures - WMA shall be placed only on properly prepared
unfrozen surfaces which are free of water, snow, and ice. The WMA shall be placed only when both the
air and surface temperatures equal or exceed 50 ̊ F for the top lift and 40 ̊ F for the bottom lift.
Asphalt Mixing Plant - The asphalt mixing plant shall be capable of producing a uniform material, have adequate
capacity, and be maintained in good mechanical condition. Defective parts shall be replaced or repaired
immediately if they adversely affect the proper functioning of the plant or plant units, or adversely affect the
quality of the hot asphalt plant mix.
Acceptable safety equipment shall be provided by the Contractor to accommodate sampling and testing.
Asphalt plant mix shall not be stored longer than nine hours, unless additional protective measures are used and
approved.
Modify the asphalt mixing plant as required by the manufacturer to introduce the WMA technology. Plant
modifications may include additional plant instrumentation, the installation of asphalt binder foaming systems
and/or WMA additive delivery systems, tuning the plant burner and adjusting the flights in order to operate at
lower production temperatures and/or reduced tonnage.
Hauling Equipment - Trucks used for hauling asphalt mixtures shall have tight, clean, smooth metal beds thinly
coated with a minimum amount of paraffin oil, lime solution, or other approved release agent. Petroleum
distillates such as kerosene or fuel oil will not be permitted. Each truck shall have a cover of canvas or other
suitable material to protect the mixture from the weather.
Asphalt Pavers - Self-propelled asphalt pavers shall be provided and equipped with an activated screed assembly,
heated if necessary, capable of spreading and finishing the asphalt plant mix material in lane widths applicable to
the typical section and thicknesses shown in the Contract. Pavers used for shoulders and similar construction shall
be capable of spreading and finishing courses of asphalt plant mix material in widths shown in the Contract.
The paver’s receiving hopper shall have sufficient capacity for a uniform spreading operation and shall have an
automatic distribution system that will place the mixture uniformly in front of the screed.
The screed or strike-off assembly shall produce the specified finished surface without tearing, shoving, or gouging
the mixture.
Use an equipment and WMA technology capable of producing an asphalt mixture that meet
specification requirements and is workable at the minimum placement and compaction temperature
desired, regardless of storage or haul distance considerations.
Tack Coat - When ordered by the Engineer or specified in the Contract, a tack coat shall be applied between
pavement courses.
Surface Conditioning - Irregularities in the existing pavement or base shall be brought to uniform grade and
cross section.
Prior to placing tack coat and beginning overlay work, the surface to be tack coated shall be swept to remove
accumulations of loose gravel and debris.
Asphalt plant mix shall be placed only on properly constructed surfaces that are free from substances that would
adversely affect the pavement quality.
