16‐100‐063‐03 Concrete Pavement 03000‐3

3.2 PLACING

At the Contractor’s option, the slip form or fixed form paving method may be used.

A. Slip Form Paving.

1. The contractor may use standard manufacture, slip form paving equipment capable of spreading,

consolidating, screeding and float finishing freshly placed concrete in one pass. Such equipment shall be capable of producing a homogeneous pavement to the specified cross-section, profile and density, and shall be automatically controlled in regard to line and grade.

2. Moisten dry subgrade to minimize absorption of water from the fresh concrete. Subgrade shall not be

muddy, soft, frozen, or covered with standing water when concrete is placed.

3. Use a standard manufacture longitudinal finisher capable of producing a smooth surface to the

specified cross-section. The longitudinal finisher may operate either mechanically or manually. Adjust and operate the longitudinal finisher (in conjunction with the finishing screed) so that a small roll of mortar is carried ahead of the float.

B. Fixed Form Paving.

1. Forms. Use straight, metal forms having adequate strength to support the equipment. Each section shall be a minimum of 10 feet in length. Use forms with a depth equal to the prescribed edge thickness of the concrete, a base width at least equal to the depth of the forms and without a horizontal joint. Flexible or curved forms must be approved by the Engineer. The Engineer may approve the use of wood forms in areas requiring hand finishing. Secure the forms in place to withstand the impact and vibration of the consolidating and finishing equipment without visible

spring or settlement. Extend flange braces outward on the base a minimum of ⅔ the height of the

form. Remove forms with battered top surfaces or bent, twisted or broken forms. Do not use repaired forms until they have been inspected and approved by the Engineer. Do not vary the top

face of the form from a true plane more than ⅛ inch in 10 feet, and do not vary the vertical face of

the form by more than ¼ inch. The forms shall contain provisions for locking the ends of abutting form sections together tightly, and for secure setting.

2. Base Support. Provide a foundation under the forms that is compact and true to the specified grade

so that the whole length of the form will be set firmly in contact with the grade.

3. Form Setting. Set forms sufficiently in advance of the point where concrete is being placed so that

line and grade may be checked. After the forms have been correctly set, thoroughly tamp the grade mechanically at both the inside and outside edges of the base of the forms. Tightly lock form sections, free from play or movement in any direction. Do not deviate the form from true line by more than ¼ inch at any point. No excessive settlement or springing of forms under the finishing machine is permitted. Clean and oil forms before the placing of concrete.

4. Grade and Alignment. Check the alignment and grade elevations of the forms immediately before

placing the concrete and make any necessary corrections. When any form has been disturbed or any grade has become unstable, reset and recheck the form.

(14)

5. Placing & Finishing. Use an approved roller or razor finishing screed capable of finishing the pavement to the required grade, section and density. Operate the finishing screed so that a small roll of mortar is carried ahead of the screed.

6. Removing Forms. Unless otherwise provided, do not remove forms from freshly placed concrete

until it has set for a minimum of 12 hours, except auxiliary forms used temporarily in widened areas. Remove forms carefully to avoid damage to the pavement.

3.3 TEXTURING

1. Burlap Drag:Use a drag consisting of a seamless strip of damp burlap, artificial turf or cotton fabric.

Use a drag that produces a uniform, gritty texture when pulled longitudinally along the full width of the pavement. Use only drags that are clean and free of encrusted mortar.

2. Grooving Equipment:Use standard manufacture transverse or longitudinal grooving equipment

capable of covering the width of the pavement in a single pass. Use grooving equipment with a metal comb that is capable of producing a uniform pattern of grooves approximately 3/16 inch

wide, spaced at ¾ inch centers and ⅛ to ¼ inch deep. Small or irregular areas may be grooved by

hand methods.

a. Before final finishing is completed and before the concrete has taken its initial set, the edges of

the slab shall be carefully finished with an edger.

b. Float Finish: After the surface stiffens enough to support the operation, float with hand floats or

powered disc floater. Check the concrete surface to insure level and smoothness, cutting down high spots and filling in low areas.

c. Broom Finish: Immediately after the concrete has received a float finish, produce a coarse

transverse scored texture by drawing a concrete broom across the surface. Striations shall be perpendicular to the direction of traffic.

d. With jointer or saw, cut control joints to ¼ of the depth of the slab. Consult the City Engineer

for joint spacing requirements. Where control joints meet, they shall not form tees or angles of less than 70º. Where tees or reentrant corners are unavoidable, a 4-foot length of #4 rebar shall be embedded in the top half of the slab as a crack stop.

3.4 CURING AND PROTECTION

1. Protection from Mechanical Injury: During the curing period, the concrete shall be protected from damaging mechanical disturbances, such as load stresses, heavy shock, and excessive vibration. All finished concrete surfaces shall be protected from damage caused by construction equipment or materials, application of curing procedures, pedestrian traffic, rain or running water. Concrete injured by any of the above actions shall be removed and replaced at the expense of the Permit holder.

2. Cold Weather Placement: When placing concrete after the first frost or when the mean daily temperatures are below 40º F, the following requirements apply. Use a specified accelerator in the concrete. Maintain concrete temperature at a minimum of 55º F for not less than the time required for the duration of barricade placement. Do not place concrete without approval of the City Engineer on days when the temperature at 9:00 a.m. is below 30º F. Do not place concrete until the outside air

(15)

16‐100‐063‐03 Concrete Pavement 03000‐5

temperature is 35º F and rising and stop pouring when the temperature reaches 40º F and is falling. When concrete has been placed and the temperature may drop below 35º F, spread insulated curing blankets over the concrete to prevent freezing of the concrete. These blankets should be left on at least 2 days to assure proper curing, if the temperatures remain below 40º F. Concrete injured by frost action shall be removed and replaced at the expense of the Permit holder.

3. Hot Weather Placement: When air temperature is expected to exceed 95º F, the Permit holder shall

use hot weather placement procedures in placing, finishing, protecting, and curing the concrete. The temperature of the concrete at the time of placement shall not exceed 90º F. Provide protection to prevent rapid drying. Start finishing and curing as soon as possible. Water reducing retarding admixture may be used.

4. Use white pigmented, wax-resin based curing compound, ASTM C309, Type II, Class B, if

required by the City Engineer.
