Scope of Work
South Parking Lot & Walking Path
IA. SCOPE OF WORK – MASON MIDDLE SCHOOL
It is the intent of this project to cold mill the existing asphalt pavement, and aggregate base, to
a depth sufficient to allow the placement of five inches of new asphalt in the Parking Lot, as
indicated on the enclosed satellite image. The existing pavement consists of three and three
quarter, to eight inches of asphalt on a good quality aggregate base. Once the above work is
completed, the contractor will proof roll the aggregate base with a loaded truck, which meets the
approval of the engineer, to determine if there are any soft or unstable areas. If any of these
conditions are encountered, the contractor will do subgrade undercutting, type II as indicated by
the engineer. In these undercut areas, drainable fill shall be used up to the bottom of the existing
aggregate base. Aggregate base required to complete the undercut areas shall be acceptable
to the engineer. This item shall be included by the cubic yard.
Four-inch, geotextile wrapped, underdrains shall be installed as directed, bedded in pea stone,
and connected to the existing drainage structures. The actual placement of these underdrains
will be determined in the field, by the engineer, and the costs associated with tapping into these
structures, as well as costs associated with the removal of excavated spoils, shall be incidental
to the under drain pay item. .
Throughout the duration of this project, the contractor shall have available a water truck, capable
of sprinkling the grade, and maintaining the moisture content of the aggregate base to within
two percent on either side of the optimum moisture content. The costs associated with this shall
be incidental to other items. Drainage structures shall be adjusted as directed, with the intent of
salvaging and re-utilizing the existing cast iron frames and grates.
Once the preceding work has been completed, asphalt pavement will be placed. The new
asphalt pavement shall consist of three- and one-half inches of 3C Modified base course, apply
a bond coat (SS-1H), followed by one- and one-half inches of 5C Modified surface course.
Minimum traffic control shall provide for safe ingress and egress, and protection of residents,
staff, faculty parents, students, and emergency vehicles, from the construction operation. A
traffic control plan provided by the contractor shall be approved by the engineer. Temporary
ramps, as required, shall be incidental to other work items.
All materials not incorporated into the work will be removed from the site; any areas that are
disturbed by the construction will be repaired to a “like” condition. Payment for this work will be
included in other items of work.
When aggregate base is accepted by Glen the Engineer, the Contractor will install three- and
one-half inches of 3C Modified Hot Mix Asphalt Base, a bond coat, and one- and one-half inches
of 5C Modified Hot Mix Asphalt Surface. Curb and gutter shall be removed and replaced, as
directed to match the existing. Existing drainage structures shall be adjusted as necessary,
and shall be paid for individually.
.
Contractor is responsible for all layout and grade staking and shall be considered incidental to
other items of work.
All permits will be obtained by the Contractor.

IA. SCOPE OF WORK – NORTH AURELIUS ELEMENTARY WALKING PATH
It is the intent of this project to remove the existing 5 ft wide asphalt walking path, and replace it
with six inches of new aggregate base, and three inches of new asphalt. The existing pavement
consists of two- and one-half inches of asphalt placed directly on soil. The aggregate base in
the new path will be 11ft in width, and the new asphalt shall be 10ft in width. Once the earth
work is completed, the contractor will proof roll the base with a loaded truck, which meets the
approval of the engineer, to determine if there are any soft or unstable areas. If any of these
conditions are encountered, the contractor will do subgrade undercutting, type II as indicated by
the engineer. In these undercut areas, drainable fill shall be used up to the bottom of the base.
This item shall be included by the cubic yard.
Four-inch, geotextile wrapped, underdrains shall be installed as directed, bedded in pea stone,
and connected to the existing drainage structures. The actual placement of these underdrains
will be determined in the field, by the engineer, and the costs associated with tapping into these
structures, as well as costs associated with the removal of excavated spoils, shall be incidental
to the under drain pay item.
New 6-inch aggregate shall be MDOT 21AA LIMESTONE. Crushed concrete will not be
acceptable.
Once the preceding work has been completed, asphalt pavement will be placed. The new
asphalt pavement shall consist of three inches of 13A Modified base placed in a single course.
In the walking path only, the average in-place density of the mixture shall be a minimum of 92
percent of theoretical maximum density.
Minimum traffic control shall provide for safe ingress and egress, and protection of residents,
staff, faculty parents, students, and emergency vehicles, from the construction operation. A
traffic control plan provided by the contractor shall be approved by the engineer. Temporary
ramps, as required, shall be incidental to other work items.
All materials not incorporated into the work will be removed from the site; any areas that are
disturbed by the construction will be repaired to a “like” condition. Payment for this work will be

II. TERMINOLOGY
Quality Control (QC) - All activities that have to do with making the quality of a product what it
should be, including training, materials sampling and testing, project oversight, and
documentation.
Quality Assurance (QA) - All activities that have to do with making sure the quality of a product
is what it should be, including materials sampling and testing, construction inspection, and
review of contractor quality control documentation.
Bituminous Mix Design - The selection and proportioning of aggregate(s), mineral filler (if
required), reclaimed asphalt pavement (RAP) and asphalt binder such that the specified mixture
design criteria are met. Laboratory evaluation is required to determine if the stated mix design
complies with specifications.
Job Mix Formula (JMF) - A bituminous mixture for a specific project. This may include
adjustments to the mix design to optimize the field application.
Target Value - A JMF parameter value that may be adjusted, if approved by the engineer, to
account for changes in the physical properties of the mixture.
JMF Adjustment - The contractor may propose an adjustment to the JMF based upon QC and/or
QA test results. The proposed JMF must meet the requirements of the 2003 Standard
Specifications for Construction. When approved by the engineer, a JMF adjustment may be
applied retroactively to one lot, for parameters with target values.
Voids in Mineral Aggregate (VMA) - The volume of void space between the aggregate particles
of a compacted paving mixture that includes the air voids and the asphalt binder, including the
absorbed asphalt binder, expressed as a percent of the total volume of mixture.
Effective Specific Gravity (Gse) - The ratio of the oven dry weight in air of a unit volume of an
aggregate (excluding voids permeable to asphalt) at a stated temperature to the weight of an
equal volume of water at a stated temperature.
Bulk Specific Gravity of Aggregate (Gsb) - The ratio of the oven dry weight in air of a unit volume
of an aggregate at a stated temperature to the weight of an equal volume of water at a stated
temperature.
Maximum Specific Gravity of Mixture (Gmm) - The ratio of the weight in air of a unit volume of
an uncompacted bituminous paving mixture at a stated temperature to the weight of an equal
volume of water at the same temperature.
Lot - Bituminous mixture produced and placed under this special provision is evaluated on a lot-
by-lot basis. A lot is made up of a discrete tonnage of one mixture. Each lot is made up of three
sublots. These sublots will be of approximately equal size up to a maximum of 2000 metric tons.
The sublot size shall be approved by the engineer prior to the start of production. The contractor

Scope of Work
South Parking Lot & Walking Path
may request a change in the sublot size during production based upon the contractor’s ability to
produce a mixture that meets the specification contained within the contract documents, and
upon approval of the engineer.
If only one or two sublots are included in a lot at the end of production, they will be combined
with the previous lot using the same mix, and this combined lot will be evaluated based upon all
sublot samples.
Lot Average Test Result - The average of all sublot QA test results, for a specific parameter, for
the lot. Test results for any sublot removed from the project will not be used in calculating a lot
average. However, the replacement material will be tested and the results included in the lot
average.
Process Quality Control Targets - These targets are established by the contractor based upon
initial production lot test results (and from any approved trial run) for air voids, VMA, asphalt
binder content and Gmm. QC tolerances will be applied to these established targets to
determine the need for production changes, including stopping production, to control the quality
of the product. Process quality control targets must be reported to the engineer prior to the end
of placement of the second lot.
Rounding of Numbers - Rounding of numerical data will follow ASTM E 29-93a, as described in
the MDOT Bituminous QC/QA Procedures Manual of Field Testing.
Random Sampling - Selection of QA samples (bituminous mixture and density) and verification
samples will be by a random process managed by the engineer. The engineer will use a random
number generating calculator to determine the locations of each density core and mixture
sample.
The contractor will be given the opportunity to observe the sampling process. However, the
random numbers selected and the sampling locations will not be revealed to the contractor until
the time of sampling in order to avoid bias in the random sampling process.
III. SAMPLING AND TESTING
The following sampling and testing procedures are to be followed in completing this work.
ASTM D 1559-89 Test Method for Resistance to Plastic Flow of Bituminous Mixtures Using
Marshall Apparatus (Section 4.5).
ASTM D 2172 Test Methods for Quantitative Extraction of Bitumen from Bituminous Paving
Mixtures.
ASTM D 2041 Test Method for Theoretical Maximum Specific Gravity and Density of Bituminous
Paving Mixtures.
ASTM D 2726 Test Method for Bulk Specific Gravity and Density of Compacted Bituminous
Mixtures Using Saturated Surface-Dry Specimens.
ASTM C 136 Test Method for Sieve Analysis of Fine and Coarse Aggregates.
