BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF STEPHENVILLE: Article II of Chapter 16 of The Code of Ordinances of the City of Stephenville is hereby amended as follows: ARTICLE II. CURBS AND GUTTERS Section 16-40. Compliance with article. Any curb and gutter constructed by the city or by any person on and immediately adjacent to any public street or alley shall conform to the specifications and requirements prescribed in this article. Section 16-41. PERMIT REQUIRED; Application. Any person who desires at his cost and expense to cause construction of concrete curb and gutter within any street, alley, or public thoroughfare within the city, before doing such construction or placement of any material, shall apply to the Building Inspector for a permit. The application for such permit, as defined in the Stephenville Building Code, shall describe in writing the street or section of street, alley or public thoroughfare on which the applicant desires to place such curb and gutter and the exact location thereof by block number or by its location with reference to inter- secting streets, avenues, alleys or other public thoroughfares. Section 16-42. MATERIALS: a. Concrete - Concrete curb and gutter shall be constructed of Class "A" Concrete (5 sack concrete-3,000 pounds at 28 days). Mortar topping if used shall be eight (8) sack concrete with sand. b. Reinforcement - Reinforcement shall be as shown in Figures 2 and 3 of the Typical Details For Curb and Gutters. Section 16-43. CONSTRUCTION: No concrete shall be placed unless the subgrade, forms, and reinforcement have been checked and approved by the Director of Public Works or his agent. Concrete shall be deposited on a moist subgrade. During placing, the concrete shall be thoroughly spaded next to the forms and shall be carefully tamped, using an approved tamper, in uniform layers not exceeding six inches in depth, until a uniformly dense concrete is obtained. No concrete over thirty (30) minutes old or retempered concrete shall be used. After the placing of the concrete has sufficiently advanced, the concrete shall be struck off with a "mule" cut to the exact section as shown in Figure 2 of The Typical Details For Curb and Gutters. If the Contractor elects to use a mortar topping on the curb and gutter -section to facilitate finishing, a first pass over 179 the rough concrete may be made with a "mule" which will strike off as much as 1/4 inch short of finish grade. If this method is used, the topping must follow the initial place- ment immediately. The finish mule must be cut to the exact section shown in Figure 2 of The Typical Details for Curb and Gutters and must in no case fall more than 50 feet behind the initial strike -off. Any section which is allowed to attain initial set before the application of the topping, or which has in any way been handled in a manner which would tend to jeopardize the complete bonding of the two courses will be removed and replaced at the direction of the Director of Public Works or his agent. As soon as the concrete has set sufficiently to retain its shape without support of the forms, the clamps and spreaders may be removed. Forms shall remain in place at least twenty- four (24) hours after completion of work. All honeycombed areas disclosed by removal of forms shall be immediately corrected by use of cement mortar. The top of all the work and the face of all curbs will be checked for irregularities as soon as the surface is finished, using a ten -foot straightedge; all variations greater that V4 inch in ten feet shall be immediately corrected. All curb and gutter shall be marked every five (5) feet and a one -half -inch premoulded joint of like cross-section shall be installed at every eighth mark and at all points of cur- vature and tangency at intersections. Three No. 4 round, smooth dowel bars twenty-four (24) inches long shall be installed at each of these expansion joints. One-half of the dowel shall be coated with asphalt and terminated with an expansion cap. a. Subgrade: The subgrade shall be scarified, mixed, reshaped by blading, sprinkled, and tamped to 95% stan- dard proctor density at approximately optimum moisture. The process shall be performed to the end that a minimum six-inch layer of compacted subgrade is secured imme- diately below the bottom of the curb and gutter and extending one (1) foot beyond the back of curb. The subgrade shall be checked for grade, and any portion thereof which falls below the grades shown on the plans shall be filled to plan grade with sand at the expense of the Contractor. b. Forms: The forms shall be of wood or metal, straight and free from warp, and of sufficient strength to resist springing during the process of depositing and com- pacting the concrete. Straight forms of wood shall be two-inch nominal thickness surfaced plank, or of metal of an approved section with a flat surface on top and bottom. Curved forms shall be used on radii and may be of flexible wood or metal. These forms shall be of a depth equal to the depth of the concrete section in which they are in contact and so designed as to permit securely fastening together in correct position. Forms shall be securely staked, braced, and firmly held to the required line and grade, using approved spreaders and clamps, and shall be sufficiently tight to prevent leakage of mortar. All forms shall be cleaned thoroughly and wetted before the concrete is placed against them. c. Finishing: Finishing will commence as soon as the concrete is workable. An edging tool, so designed to cut a radii is to be used on the back edge of the curb, the street edge of the gutter and at points where dividing plates were placed. The entire area of the curb and gutters is to be brushed with a moist brush to a carpet finish. Sections where dividing plates have been left in until the structure was fractured when they WE were removed will not be accepted and will have to be taken out and removed. The Contractor will take proper steps to protect the structure. The Director of Public Works or his agent will be the sole judge as to any additional steps for protection to the curb and gutter. d. Curing: Concrete shall be cured with the application of a two (2) membrane curing compound. This liquid membrane -forming compound for curing concrete pavement shall conform to the requirements of A.S.T.M. Designation C309 for Type 2, White Pigmented Compound (other colors will not be permitted). The material shall have minimum flash point of 80°F when tested by the "Pensky-Martin closed cup method." When applied at the proper consistency through an anato- mizing nozzle by means of approved pressure equipment, the compound shall produce a fine mist which shall pro- vide a firm, continuous, uniform moisture impermeable film, free from pinholes, which shall adhere satisfac- torily to the surface of the damp concrete without running off or appreciably sagging. Under normal conditions and at the specified rate of coverage, the material shall be dry to the touch in not more than four (4) hours. During the curing period of 72 hours, the material shall not disintegrate, check, peel, or crack. e. Backfilling, Sloping, and Finishing: As soon as the curb forms are removed, backfilling of the curb will commence. It is important that backfilling be given special attention to protect the new curb. Select material shall be used for backfill, which will not include rocks or other foreign material that might damage the curb. Backfill shall be thoroughly compacted and neatly graded off of the top of curb. When curb and gutter is constructed in residential area, the top 4 inches of backfill dirt will be topsoil or other approved soil which will support the growth of lawn grasses. All construction materials, items of excavations and other foreign matter collected during the process of construction, will be disposed of in an acceptable way before the job is accepted. Section 16-44. EXISTING PAVEMENT. a. In all cases where the property owner or the contractor acting for the property owner constructs curbs and gut- ters adjacent to an existing topped or improved street, the property owner or any contractor acting for the pro- perty owner will replace and repair any damage done to the existing pavement and all gutters constructed will be on a level with the existing pavement. b. In the event any person shall fail to repair any damage to existing pavement or shall construct a gutter which is not on the level with existing pavement, the city shall repair such damage and correct any defective gutter, and assess the cost therefor. In addition thereto, the property owner or contractor shall be sub- ject to the penalty provided in this article. Section 16-45. INSPECTIONS. The Director of Public Works of the city shall inspect all curb and gutter construction, which shall be subject to his approval in regard to meeting the details, speci- fications and requirements set out in this article. 181 Section 16-46.
