SPECIFICATIONS FOR

CONCRETE WALKS AND CURBS

1. SIDEWALKS

A. GENERAL - All concrete walks referred to herein shall mean all pavement designated on drawings as "Concrete Walks", "Conc. Walks". All concrete walks are to be one course constructed to the width and thickness designated on the drawings. See Sidewalk Standard

Details.

B. SUB-BASE

(a) Preparation - The surface shall be stripped of all loam, muck, old pavement, organic and other objectionable material. All soft and spongy places shall be removed and shall meet CT DOT Form 817 Article M.02 requirement. Sub-base shall be thoroughly compacted in layers not exceeding six (6) inches in thickness. Material for sidewalk sub-grade shall meet the requirement of section M.03.02 for Class C Concrete.

(b) Deep Fills - Fills exceeding foot shall be considered deep fills. Deep Fills shall be made with clean fill material free of muck, loam, clay, spongy or perishable material. Fill material shall be spread in layers not exceeding one foot in thickness and each layer thoroughly compacted. The top of all fills shall extend beyond the walk on each side at least one and one-half (1 1/2) feet. Fill material shall be brought to within one (1) foot of finish sub-grade.

The final foot of fill shall be made with bank gravel spread in two (2) layers. Each shall be compacted to a six (6) inch depth. Rolling shall be done by a self-propelled roller weighing not less than four (4) ton. Any areas inaccessible to the roller shall be hand-rolled and tamped. The gravel base is to be smooth and true to grade, as shown on the drawings.

(c) Wetting -While compacting the sub-base, the material shall be thoroughly wet, and shall be damp when the concrete is deposited but shall show no pools of water.

C. FORMS

(a) Materials -Forms shall be free from warp and of sufficient strength to resist springing out of shape.

(b) Setting -The forms shall be well staked or otherwise hold to the established lines and grades and their upper edges shall conform to the established grade of the walk and shall extend to the bottom of the concrete and shall be banked with earth or supported and sealed by some other approved method to prevent leakage unless otherwise noted.

(c) Treatment - All wood forms shall be thoroughly wetted and metal forms oiled with non staining oil before depositing any material against them. All mortar and dirt shall be removed from forms that have been previously used.

(d) Removal - Forms shall remain in place until the concrete has thoroughly hardened but the dividing plates shall be removed promptly after the concrete is of sufficient hardness to prevent slabs from flowing together.

D. EXPANSION JOINTS - A one-half (12) inch joint shall be provided once every twenty

(20) feet, which shall be filled up to one-half (12) inch below the surface of the walk with suitable material. All construction and expansion jointing shall extend to the bottom of the concrete and radial joints shall be installed on curved walks. A similar joint shall be provided at each intersection of sidewalk and street curb and each intersection of sidewalk with concrete driveway. Sidewalks shall be separated from abutting buildings by a one-half (1/2) inch joint.

E PLACING - After mixing, the concrete shall be handled rapidly and the successive batches deposited in a continuous operation completing individual sections to the required depth and width. Under no circumstances shall concrete that has partly hardened be used. The forms shall be filled and the concrete brought to the established grade by means of strike board or straight edge. The method of placing the various sections shall be such as to produce a straight clean-cut joint between them, so as to make each section an independent unit. Any concrete in excess of that needed to complete a section at the stopping of work shall not be used. In no case shall concrete be deposited upon a frozen sub-grade or sub-base.

F.FINISHING

(a) After the concrete has been brought to the established grade by means of a strike-board, it shall be worked with a wood float to the desired surfaces hereinafter specified. In no case shall dry cement or a mixture of dry cement and sand be sprinkled on the surface to absorb moisture or to hasten hardening. The entire sidewalk shall be jointed or flagged in sections equal to the width of the work or as otherwise directed by the Director of Public Facilities. The surface edges of all slabs shall be rounded to a radius of one-half (1/2) inch, unless otherwise specified by the Director of Public Facilities.

(b) SURFACE - The surface shall be floated with a wooden float only, producing an even, gritty finish. On wide sidewalks the finishing may be done with two applications of a canvas belt, not less than six (6) inches wide, and about two (2) feet longer than the width of the sidewalk. For the first application, the belt shall be drawn across the surface with vigorous strokes at least twelve (12) inches long, and moved ahead very slightly at each stroke. The second application shall be given immediately after the water glaze or sheen disappears, and the stroke of the belt shall be no more than four (4) inches, while the longitudinal motion shall be greater than during the first application.

G. CURING - Curing of concrete shall be by use of colorless membrane type curing material which shall not permanently discolor the surface or by moisture retaining covers of burlap, cotton, or watertight paper. Where curing compounds are used it shall be suitable to seal the surface of the concrete in one application and shall harden within 60 minutes after application.

Curing material shall be applied to all exposed surfaces by means of approved spraying equipment. It shall be sprayed uniformly to the surface as soon as possible after free surface water has disappeared from the concrete surface at a rate of one gallon per 200 square feet.

Where moisture retaining covers are used, care shall be taken to cover the entire concrete surface including exposed sides of members. The covers shall be kept constantly moist and have sufficient strength to withstand wind and abrasive action. Covers shall be placed as soon as possible after free surface water has disappeared and the surface is hard enough to resist marring from the covers. Covers shall remain in place for seven (7) days.

http://shall.be megha.jain Line

H. PROTECTION - The freshly finished curb shall be protected from hot sun and drying winds until it can be sprinkled and covered as above specified. The concrete surface must not be damaged or pitted by rain drops, and the contractor shall provide and use, when necessary, sufficient covering to completely protect all sections that have been placed within the preceding twelve (12) hours The contractor shall erect and maintain suitable barriers to protect the curb from traffic and any section damaged from traffic or other causes, shall be repaired or replaced by the contractor at his own expense in a manner satisfactory to the Director of Public

Facilities.

I. TEMPERATURE - If, at any time during the progress of work, the temperature is 40 degrees Fahrenheit and falling, concrete will not be placed unless specifically pennitted by the

Director of Public Facilities. Cold Weather curing of sidewalk must be approved by the

Department of Public Facilities.

J. METHOD OF PAYMENT - Compensation for concrete sidewalks shall be made at the unit price bid per square foot in the Proposal. Said price shall include all materials, equipment and labor necessary for grading, preparation of the sub-base, forming, placing, curing and protection of the completed work.

2. CONCRETE CURBS

A. GENERAL - Concrete curbs shall be of the size and shape as shown on the Drawings.

The top corner of the face shall be rounded to the radius of at least one (1) inch and the top corner on the back of the curb shall also be neatly rounded with special tools.

See Standard Details for Concrete Curbs.

B. SUB-GRADES - The material underlying the concrete curbs shall be satisfactory and thoroughly compacted to an even bearing sub-grade. Any unsuitable material, in the opinion of the Director of Public Facilities shall be removed and replaced with acceptable material and compacted.

C. FORMS

(a) MATERIALS - Forms shall be free from warp and of sufficient strength to resist to sprining out of shape.

(b) SETTING - The forms shall be well staked or otherwise held to the established lines and grades and their upper edges shall conform to the established grade of the curb and shall extend to the bottom of the concrete, and shall be banked with earth or supported by some other approved method to prevent leakage.

(c) TREATMENT - All wood forms shall be thoroughly wetted and metal forms oiled with a non-staining oil before depositing any material against them. All mortar and dirt shall be removed from forms that have been previously used.

(d) REMOVAL -Forms shall remain in place until the concrete has thoroughly hardened but in no case less than eighteen (18) hours after pouring.

D. PLACING - Concrete shall be placed carefully so as not to disturb the alignment and position of forms. Sufficient spading or vibrating shall be done along the forms to ensure smooth, dense surfaces.

E. FINISHING -The top of the curb shall be finished by troweling; all joints shall be tooled with approved edging tool. Immediately upon removal of the forms all exposed surfaces shall be rubbed to a smooth, uniform and even surface by means of a soft rubbing brick or carborunrum stone. Plastering with mortar to finish or build up will not be permitted. Should any portion of the surface or face of the curb depart more than one-fourth (1/4) of an inch from a straight edge ten (10) feet in length placed on the line of the curb, or should any part of the exposed surface present a wavy appearance, the same will be sufficient cause for rejection of that portion of the work.

F. JOINTS - All concrete curbs shall be jointed or flagged in sections approximately six (6) feet in length. Where walks and curbs are combined, jointing or flagging shall be at the same spacing and locations as specified for walks.

G. EXPANSION JOINTS - A one-half (1/2”) inch joint shall be provided at least every twenty

-five (25) feet, which shall be filled up to one-half (1/2”) inch below the surface of the curb with suitable material. All construction and expansion jointing shall extend to the bottom of the concrete. A similar joint shall be provided at each intersection of sidewalk and street curb.

Where walks and curbs are combined, expansion joints shall be placed at the same spacing and location as specified for walks.

H. CURING - Curing of concrete shall be by use of colorless membrane type curing material which shall not permanently discolor the surface or by moisture retaining covers of burlap, cotton, or watertight paper. Where curing compounds are used it shall be suitable to seal the surface of the concrete in one application and shall harden within 60 minutes after application.

Curing material shall be applied to all exposed surfaces by means of approved spraying equipment. It shall be sprayed uniformly to the surface as soon as possible after free surface water has disappeared from the concrete surface at a rate of one gallon per 200 square feet.

Where moisture retaining covers are used, care shall be taken to cover the entire concrete surface including exposed sides of members. The covers shall be kept constantly moist and have sufficient strength to withstand wind and abrasive action. Covers shall be placed as soon as possible after free surface water has disappeared and the surface is hard enough to resist marring from the covers. Covers shall remain in place for seven (7) days.

I. PROTECTION - The freshly finished curb shall be protected from hot sun and drying winds until it can be sprinkled and covered as above specified. The concrete surface must not be damaged or pitted by rain drops, and the contractor shall provide and use, when necessary, sufficient covering to completely protect all sections that have been placed within the preceding twelve (12) hours. The contractor shall erect and maintain suitable barriers to protect the curb from traffic and any section damaged from traffic or other causes, shall be repaired or replaced by the contractor at his own expense in a manner satisfactory to the Director of Public

Facilities.

3. STONE CURB
