These standards and the standards of the city's Subdivision Regulations (see Chapter 18 of this Code) will apply to all streets constructed in the City of Weatherford by developers. The standards will cover subgrade, base course, and surface course of the following type streets as shown in the new addition regulations. The following classification shall apply:
1. 
Original Town Sight Installation Specifications. Installation of streets, curb and gutters in the original town sight not covered prior to this date shall meet standards approved by the city in accordance with the original town sight areas.
2. 
Utility, Alley, And Building Line Specifications. All new additions shall have a minimum 15 feet building line designated. Alleys shall have an easement specification for sanitation pick up and gas and sewer installations. All water lines shall be placed in the right-of-way between the installed curb and property line. All alley right-of-way width minimum 20 feet.
3. 
New Addition Regulations. All street right-of-way width minimum 50 feet:
a. 
Residential streets 32 feet back to back of curb.
b. 
Secondary thoroughfares minimum 32 feet back to back curb, wider if specified by the city.
In general, residential streets shall consist of properly prepared subbase, concrete curb, and gutter, six inches of approved base course, and two inches of hot laid hot mix asphaltic concrete, or five inches Portland concrete paving on two inches of sand cushion; secondary thoroughfare shall consist of the above except hot laid asphalt shall be four inches thick, and concrete slab shall be six inches thick.
1. 
The bottom of the excavation for the pavement or base course shall be known as the pavement subgrade, and shall conform to the lines, grade, and cross section shown on the plans.
2. 
All soft and yielding material and other portions of the subgrade which will not compact readily when rolled or tamped shall be removed as directed and replaced with suitable material placed and compacted at, or slightly above, the optimum moisture content. In the absence of standard testing, a reasonable evaluation of moisture content may be made by squeezing a ball of damp soil in the hand. If the ball is so dry that it crumbles easily, additional water should be mixed into the soil. If it is so wet that free water comes to the surface when kneaded, the subgrade should be permitted to air out before final rolling. The subgrade shall be thoroughly compacted with suitable equipment to secure a 95% proctor density.
1. 
The base coverage shall be native gravel or other such material as the City of Weatherford may approve.
2. 
Type of base and thickness required:
a. 
Stabilized aggregate base course: Class 1-A, Class 2-A, Class 3-A, six inches of the base will be required in all streets unless specified by city for special conditions.
b. 
Class 1-A soil-cement base: The base shall be six inches thick on all streets and constructed in accordance with Section 312 State Highway Standard Specifications.
c. 
Class 2-A soil-asphalt base: The base shall be six inches thick on all streets and constructed in accordance with Section 313 State Highway Standard Specifications.
d.

3. 
A tack coat of asphaltic material shall be placed between the base course and surface course unless waived by the City of Weatherford. There shall be tests run on the base course on each 1,000 square yards, by a recognized laboratory, and the tests results shall be furnished to the city.
Section 609 Oklahoma State Highway Specifications shall be a part of these standards:

2. 
All curb and gutters shall be of 3,500 pounds compressive strength portland cement concrete at 28 days. One inch contraction joint shall be every 18 feet and expansion joint every 72 feet. Should crushed stone aggregates be used, the spacing may be immediately after finishing operations are completed.
3. 
A white pigmented curing membrane, if used should be placed in ample quantities and completely cover all exposed surfaces. Wet burlap, if used, must completely cover all surfaces and be kept in a saturated condition for at least seven days. All curb and gutters shall be mulled and finished with a broom finish and backfilled as soon as possible after forms are removed to prevent undermining.

On forty-four-foot slabs, three joints will be required, two of which will be sawed contraction joints, and one construction joint with dowels as specified above.
All construction joints shall be doweled with 5/8 inch smooth dowel on eighteen-inch centers.
Contraction joints shall be spaced every 20 feet. They shall be sawed to a depth of 1/4 the thickness of slab and filled with mastic material. No dowels will be required.
Transverse expansion joints shall be spaced not over 300 feet of slab and at the slab returns. Expansion joints shall have non-extending filler, 5/8 inch dowels at eighteen-inch centers with expansion caps. All dowel bars shall be coated with heavy grease to prevent binding to concrete.
