2515.01 DESCRIPTION.
This work shall consist of removal of paved drives or portions of drives, and construction of new PCC driveways in accordance with the contract documents.

Areas of paved driveways which are not designated to be removed but which are broken or removed by the Contractor's operations shall be replaced by the Contractor without compensation.

2515.02 MATERIALS.
When paved driveways are to be constructed in conjunction with a PCC paving project, the class of concrete being used on the project may be used for driveways. If the contractor does not elect to use the class of concrete specified for the pavement or the contract contains no item for PCC pavement, pavement widening, or base, then Class C concrete shall be used.

The materials used in construction of paved driveways shall meet requirements of Division 41.

2515.03 REMOVAL OF PAVED DRIVEWAYS.
Paved driveways shall be removed as shown in the contract documents. When old concrete pavement is to be removed and later abutted at its top surface with new concrete pavement, the designated breakout line shall be sawed to full depth before breaking the pavement. Any concrete broken or damaged beyond the breakout line designated by the Engineer shall be removed to a new line and replaced by the Contractor at the Contractor's expense.

Article 2510.02 shall apply to the removal of driveways.

2515.04 CONSTRUCTION OF PAVED DRIVEWAYS.
Unless otherwise specified, new paved driveways shall be constructed to the dimensions shown in the contract documents.

A. Preparation of Subgrade.
The subgrade shall be prepared by excavating or filling with suitable earth to a depth below the finished grade line so that, when tamped or rolled until smooth, firm, and hard, the subgrade will be uniform and at the required depth below the finished grade line.

B. Portland Cement Concrete.

1. Placing.

a. Hand Finish.
Forms of wood or steel shall be in accordance with Article 2301.07, A, 1, b.

The subgrade shall be thoroughly moistened. Concrete shall be deposited for the full depth of slab in one operation. It shall be consolidated by tamping or vibration, and the excess concrete screeded off flush with the forms. Edges adjacent to all forms, expansion joints, curbs, or fixtures in the surface shall be thoroughly consolidated.

b. Slip Form.
Self propelled slip form pavers shall meet the requirements of Section 2301. Other slip form paving machines shall be approved by the Engineer and designed for the specific purpose of placing, consolidating, and finishing concrete driveway slabs without use of fixed side forms.

2. Finishing.
After consolidation, the concrete surface shall be finished with a burlap drag.

After the surface has been floated, the edges of the slabs shall be finished with a suitable edging tool.

3. Protection and Curing.
After finishing, the concrete shall be cured and protected by one of the methods described in Article 2301.19.

4. Joints.
The concrete shall be cut through for not less than 25% of the depth with a pointed trowel or suitable spading tool, and the concrete edged on both sides. In lieu of using a pointed trowel or suitable spading tool, the Contractor may cut these lines within 12 hours after placement of concrete with a 1/8 inch (3 mm) blade saw that is approved by the Engineer. Metal dividers will be considered for approval, in lieu of cutting.

Isolation joints shall be constructed at all points where driveways meet other walks, curbs, or fixtures in the surface. These joints shall be constructed by installing a 1/2 inch (13 mm), full depth strip of approved premolded joint material.

Contraction joints shall be sealed according to Article 2301.25.

5. Time for Opening Pavement for Use.
PCC driveways shall be opened a minimum of 7 calendar days after placement or when flexural strength reaches 400 psi (2.75 MPa) as determined by Materials I.M. 383.

C. Hot Mix Asphalt.
HMA driveways shall be constructed in accordance with Article 2303.03 and 2303.04. Compaction shall be Class II.

D. Smoothness.
Where abutting pavement is to be placed adjacent to the pavement being checked, the surface shall not deviate by more than 1/4 inch (6 mm) when checked 1 inch (25 mm) from the edge with a 3 foot (1 m) straightedge used transversely and a 10 foot (3 m) straightedge used longitudinally.

Areas may be checked by the Engineer with a surface checker and shall not exceed 1/4 inch in 10 feet (6 mm in 3 m). For each bump exceeding these requirements, the Contractor will be assessed $50 or the bump corrected as agreed upon by the Engineer and Contractor.

E. Weight Limits.
Construction equipment on both PCC and HMA driveways shall be limited to 5 ton (5 Mg).

2515.05 METHOD OF MEASUREMENT.

A. Removal of Paved Driveway.
The quantity of Removal of Paved Driveway, in square yards (square meters), will be the quantity shown on the contract documents for each paved driveway removed to the nearest square foot (0.1 m²).

B. Portland Cement Concrete Driveways.
The quantity of PCC Driveway of the thickness specified in square yards (square meters), will be the quantity shown on the contract documents for each paved driveway to the nearest square foot (0.1 m²). This will include areas through sidewalks. No deductions will be made for fixtures having an area of 1 square yard (1 m²) or less.

2515.06 BASIS OF PAYMENT.

A. Removal of Paved Driveway.
The Contractor will be paid the contract unit price for Removal of Paved Driveway per square yard (square meter). This payment shall be full compensation for all equipment, tools, and labor for removal of the driveways as specified in the contract documents.

B. Portland Cement Concrete Driveway.
The Contractor will be paid the contract unit price for PCC Driveway of the thickness specified per square yard (square meter). This payment shall be full compensation for furnishing all material, equipment, tools, and labor to construct the driveway in accordance with the contract documents.
