feet of fiil placed for every 100 feet of roadway and 10,000 sqaare feet for
parking areas.
C. The Contractor shall locate all existing underground utilities prior to
excavation.
D. Before commencing excavation or embankment construction, the Contractor
shall remove all topsoil from the areas to be cut or filled. Sufficient topsoil
shall be salvaged to restore all disturbed areas with a minimum of 4 inches.
Placement of topsoil behind curbing shall be done prior to paving. The
topsoil shall be placed under ihis section prior to commencing the turf
restoration specified in Section 02930.
E. The Contractor shall grade all roadways or parldng areas to within plus or
minus 0.1 feet, with a minimal surplus being present. Subgrade preparation
may not be commenced until this requirement has been met.
3.02 SUBGRADE EXCAVATION
A. Subgrade excavation shall not be used to correct conditions caused by
inclement weather.
B. In cases where inclement weather is continuous and for long peziods of time,
and does not aliow for expeditious completion of subgrade preparation as
specified in Section 02225, the owner's representative may require the
Contractor to prepare the roadways as follows:
1. Make a core excavation of the subgrade to a depth as directed by the
owner's representative.
2. Replace the excavated material below subgrade with the same materials
to be used for the aggregate base material (Class 5, etc.) and then
immediately continue to place the loose material in the azea above the
subgrade elevarion. The subgrade excavation and the base course both
shall be constructed with base material in a fashion which will
contribute to "bridging". In this case, aftez the subgrade excavation
has been made and the conditions do not allow for compaction, then
the bottom of the subgrade excavation shall be subcut to a uniform
bottom and the base material shall be placed in a fashion to prevent
pumping or intrusion of the subgrade into the base material.
Generally, the first 12 inches of the material shall be deposited on the
subgrade before any rolling or compaction begins. AII compaction
done in this situarion shall be b y use of static eauipment.
3. When this procedure for subgrade excavation is used, the Contractor
shall be paid for excavating the unsuitable materials below subgrade
elevation and shall be paid for aII base materials used above and below
subgrade elevation, all at contract unit price; the compaction of this
base material shall be considered incidental. Also, when this method
is used, the Contractor shall not be paid for subgrade preparation,

shall both observe the placement of materials and if it appears that the soils
being placed will not be able to be prepared under normal subgrade
preparation and that subgrade excavation will be necessary, then the subgrade
shall be left lower than final elevation so as to eliminate having to pay for
excavation of materials that were just previously placed. Particular attention
shall be paid that capping of granular materials with non-granular materials is
not permitted at or within 12 inches of the subgrade surface.
D. Any over-excavated azeas shall be retumed to the proper grade and cross-
section by the Contractor at no additional cost to the Owner.

3.01 SU$GRADE PREPARATION
A. Upon completion of all excavation and embankment work specified in Section
02200, the Contractor shall commence Subgrade Preparation in accordance to
MNDOT 2112.
B. The required density and stability must be achieved in the top 12-inches of the
subgrade.

'
? C. Unstable areas of subgrade due to inclement weather shall be prepared by the
Contractor at no compensation; subgrade determined satisfactory and then
, failing due to inclement weather also shall be repaired at no additional
compensation.
D. The Contractor shall prepare the top 12 inches of subgrade by means of
' scarifying, aerating or watering for at least a period of 24 hours or as long as
specified by the owner's representative, in order to obtain the required stability
and density. If wet or poor soil is encountered, the Contractor shall dry it out
? for a minimum period of 24 hours in optimum drying weather or longer in other
conditions by aerating the soil by the use of blades, sheepsfoot, or other
mechanical. means. Under normal circumstances no determination as to the
? acceptability of a questionable subgrade material will be made prior to the
Contractor's drying out the soil for the minimum time period. Areas which
remain unstable after normal subgrade preparation will be repaired at the
direction of the owner's representative as to MNDOT Specification No. 2105
' (Subgrade Excavation).
The "required stabiliry" shall be such that, when test rolled, the roadbed surface
, shows yielding or rutting of no more than one and one-half inches measured
from the top of the constructed grade to the bottom of the rut.
? E. Tests shall be taken to evaluate the compaction achieved. Tests shall be taken at
the rate of one test for every 100 feet of subgrade prepared for roadways and
10,000 square feet for pazlang areas. Testing shall be by an independent test
lab retained by the owner. Under no circumstances shall gravel be hauled until
' the subgrade has been approved by the owner's representative with respect to
grade and density.
F. Subgrade preparation will be required over the entire length and width of the
' proposed roadways and parking areas, and one foot outside the back of curb.
? G. The Contractor shall notify the owner's representative when the subgrade is to
proper grade and cross-section for acceptance, before proceeding with the
aggregate base.
' 3.02 TEST ROLLiNG
A. Test rolling of the subgrade shall be done in accordance to MNDOT 2111.
' B. Test rolling shall be performed prior to, intermittently during, and after
completion of subgrade preparation work (MNDOT 2112) or subgrade
excavation work (MNDOT 2105) when ordered by the owner's representative.
? The yielding or rutting portion of this specification 2111.3 shall apply only to
the test roll for final acceptance of the subgrade preparation; earlier test rolhng
shall be for the purpose of identifying those areas needing subgrade excavation,
etc. Later test rolling on the aggregate base course shall be to determine if the

, 3.01 GENERAL
A. Construction shall be done in conformance to MNDOT 2531.3, unless
modified below.
, B. Machine Placement The slipform/extrusion machine approved shall be so
designed as to place, spread, consolidate, screed, and finish the concrete in
' one complete pass in such a manner that a minimum of hand finishing will be
necessary to provide a dense and homogeneous concrete section. The
machine shall shape, vibrate, and/or extrude the concrete for the full width
and depth of the concrete section being placed. It shall be operated with as
' nearly a continuous forward movement as possible. All operations of mixing,
delivery, and spreading concrete shall be so coordinated as to provide
uniform progress, with stopping and starting of the machine held to a
? minimum.
C. Formed Method The forms shall be of wood, metal, or other suitable
material that is straight and free from warp, having sufficient strength to
' resist the pressure of the concrete without displacement and sufficient
tightness to prevent the leakage of mortar. Flexible or rigid forms of proper
' curvature may be used for curves having a radius of 100 feet or less.
Division
lates shall be metal
p
.
The front and back forms shall extend for the full depth of the concrete. All
' of the forms shall be braced and staked so that they remain in both horizontal
and vertical alignment until their removal. They shall be cleaned and coated
with an approved form-release agent before concrete is placed against them.
' The concrete shall be deposited into the forms without segregation and then it
shall be tamped and spaded or mechanically vibrated for thorough
consolidation. Low roll or mountable curbs may be formed without the use
' of a face form by using a straightedge and templet to form the curb face.
When used, face forms shall be removed as soon as possible to permit
finishing. Front and back forms shall be removed without damage to the
' concrete after it has set.
D. Finishine The plastic concrete shall be finished smooth, if necessary, by
means of a wood float and then it shall be given a final surface texture using
, a light broom. Concrete that is adjacent to forms and formed joints shall be
edged with a suitable edging tool to the dimension shown on the plans.
' E. Joi•ntine
1. Contraction 7oints Transverse weakened-plane contraction joints shall
' be constructed at right angles to the curb line at intervals not exceeding
10 feet. Joint depth shall average at least 1/4 of the cross section of
the concrete.
, Contraction joints may be sawed, hand-formed, or made by 1/8 inch
thick division plates in the formwork. Sawing shall be done early after
the concrete has set to prevent the formation of uncontrolled cracldng.
' The joints may be hand-formed either by (1) using a narrow or

triangular jointing tool or a thin metal blade to impress a plane of
weakness into the plastic concrete, or (2) inserting 1/8 inch thick steel
strips into the plastic concrete temporarily. Steel strips shall be
withdrawn before final finishing of the concrete. Where division
plates are used to make contraction joints, the plates sha11 be removed
after the concrete has set and while the forms are still in place.
2. Expansion Joints Expansion joints shall be constructed at right angles
to the curb line at immovable structures and at points of curvature for
short-radius curves. Filler material for expansion joints shall conform
to the requirements of MNDOT 2531.213 and shall be furnished in a
single 3/4 inch thick piece for the full depth and width of the joint.
Expansion joints in a slipformed curb or curb and gutter shall be
constructed with an appropnate hand tool by raking or sawing through
partially set concrete for the full depth and width of the section. The
cut shall be only wide enough to permit a snug fit for the joint filler.
After the filler is placed, open areas adjacent to the filler shall be filled
with concrete and then troweled and edged.
Alternatively, an expansion joint may be installed by removing a short
section of freshly extruded curb and gutter immediately, installing
temporary holding forms, piacing the expansion joint filler, and
replacing and reconsolidating the concrete that was removed.
Contaminated concrete shall be discarded.
3. Other Joints Construction joints may be either butt- or expansion-type
joints. Curbs or combined curbs and gutters constructed adjacent to
existing concrete shall have the same type of joints as in the existing
concrete, with similar spacing; however, contraction joint spacing shall
not exceed 15 feet. Curbing placed in conjunction with concrete
paving shall be jointed according to the type of joint indicated on the
plan and profile.
F. Protection The Contractor shall always have material available to protect the
surface of the plastic concrete against rain. These materials shall consist of
waterproof paper or plastic sheeting. For slipform construction, materials
such as wood planks or forms to protect the edges shall also be required.
When concrete is being placed in cold weather and the temperature may be
expected to drop below 35 degrees F., suitable protection shall be provided to
keep the concrete from freezing until it is at least 10 days old. Concrete
injured by frost action shall be removed and replaced at the Contractor's
expense.
G. urin Concrete shall be cured for at least three days after placement to
protect it against loss of moisture, rapid temperature change, and mechanicat
injury. Membrane curing shall not be pernutted in frost-affected areas when
the concrete will be exposed to deicmg chemicals within 30 days after
completion of the curing period.
H. Backfilline After the concrete has set sufficiently, the spaces in front and
back of curbs shall be refilled with suitable material to the required
elevations. The fill material shall be thoroughly tamped in layers. It shall be

'
' the Contractor's responsibility to protect the curbing during all phases of the
backfilling operation. Any curbing damaged during this process shali be
? removed and replaced at the Contractor's expense.
I. Testine The Contractor shall make not less than four test cylinders of
standard size and manufacture for each 50 cubic yards of concrete placed, or
, for each day's operations unless otherwise directed by the owner's
representative. One cylinder from each set shall be tested at seven days and
one cylinder at 28 days, in accordance with ASTM C-31. The third cylinder
shall be retained as a spare in case problems occur with the other two. The
' fourth cylinder shall be field cured under the same conditions as the concrete
placed, for a minimum of 21 days and tested at 28 days in accordance with
' ASTM C-31.
To cast the cylinders, fill the molds in three equal layers and uniformly rod
each layer 25 times with a bullet-noseti rod. When rodding the second and
' third layers, the rod should just break through into the layer beneath. The
molds should be filled continuously and without interruption. After rodding
the top layer, tap the cylinder lightly to close any voids that might have
formed, trowei the top, and cover immediately to prevent loss of moisture.
' Be sure the cylinders are on a level surface during curuig and that the tops are
smooth and level to ensure minimum laboratory preparation and the best test
' results.
Test results indicating concrete substandard from the above requirements shall
be reason for halting concreting operations and investigation of the cause of
the deficiency, and removal and replacement of concrete placed during the
