| A. | Control dust, Section 01 57 00. | |
| PART 2 | PRODUCTS | Not Used |
| PART 3 | EXECUTION | |
| 3.1 | PREPARATION | |
| A. | General | |
| 1. | Coordinate utility location, Section 01 31 13. | |
| 2. | Preserve all active utilities. | |
| 3. | Notify neighborhood of day and time of operation. | |
| 4. | Make sure invert covers are properly installed in storm drain and sanitary sewer systems, Section 01 71 13. | |
| 5. | Mark existing utilities on redline drawings. | |
| B. | Traffic Control: Provide worker and public safety, Section 01 55 26. | |
| C. | Tree Roots: | |
| 1. | Avoid or minimize damage to tree roots. Roots provide anchorage, storage of energy, and absorption and conduction of water and mineral elements. Loss of root connection affects health and stability of tree and safety of people and property. | |
| 2. | Provide certified arborist observation of root cuts larger than 4 inches diameter. Notify COR 48 hours prior to such root cut. | |
| D. | Existing Surfaces: | |
| 1. | Do not damage adjacent concrete surfaces that are not scheduled for removal. | |
| 2. | Use rubber cleats or Pavement pads when operating backhoes, outriggers, track equipment, or any other equipment on or crossing paved surfaces. | |
| 3. | Restore paved surfaces that are damaged by removal operations at no additional cost to the OWNER. Match the existing Pavement surface plus 1 inch. | |
| 3.2 | SAW-CUT CURB HORIZONTALLY | |
| A. | Saw cut curbs for ADA ramps at 1:12 slope. No trip hazard at gutter flow line. | |
| B. | Saw cut curbs for flares: | |
| 1. | 1:4 slope measured to grade, or | |
| 2. | 1:12 slope measured horizontally when complying with ADA and UFAS. | |
| 3.3 | REMOVE PORTLAND CEMENT CONCRETE | |
| A. | Remove concrete to the nearest expansion joint or vertical saw cut. | |
| B. | Make concrete cuts straight, vertical to the surface, true, full depth. | |
| C. | DO NOT use machine mounted impact hammers. | |
| 3.4 | REMOVE ASPHALT CONCRETE | |
| A. | Saw cut full depth and remove Pavement. | |
| B. | When asphalt concrete overlays Portland cement concrete Pavements do not use a machine mounted impact hammer. | |
| 3.5 | MILLING | |
| A. | Machine: | |
| 1. | Equipped to prevent air pollution. | |
| 2. | Equipped with a system to control slope of mill cut. | |
| B. | Tolerances: | |
| 1. | Milling Depth: As indicated plus or minus 10 percent not uniformly high or uniformly low. | |
| 2. | Striation Texture: Uniform, discontinuous, longitudinal, 3/16 inch deep maximum, 3/4 inch center to center. | |
| 3. | Smoothness: Plus or minus 5/16 inch in 25 feet. | |
| 4. | Cross Slope: Plus or minus 1/4 inch in 10 feet. | |
| C. | Performance: | |
| 1. | Lower utility frames, covers, and other Street Fixtures. | |
| 2. | Mill surfaces to the depth shown on the Drawings or indicated by COR. Do not disfigure adjacent work or existing surface improvements. | |
| 3. | If milling exposes smooth underlying Pavement surfaces, mill the smooth surfaces to make them rough. | |
| 4. | Mill off material if it ponds water or if it has been damaged by water. | |
| 5. | Where vehicles or pedestrians must pass over milled edges provide safe temporary ramps suitable to speed of user vehicles (or suitable for wheel chair user needs). | |
| 6. | Remove excess material and clean milled surfaces. | |
| 7. | If work equipment is removed from the milling site and milled surface awaits further work, provide appropriate traffic control and cleaning. | |
| 3.6 | GRINDING | |
| A. | Machine: | |
| 1. | Cutting head 36 inches wide minimum. | |
| 2. | 50 to 60 diamond blades per foot of head. | |
| B. | Preparation: | |
| 1. | Control traffic. | |
| 2. | Provide water truck, waste truck, and other support machinery. | |
| 3. | Mark areas to be ground. | |
| C. | Tolerances: | |
| 1. | 1/4 inch lip transverse to the direction of vehicular travel. Potential for ponding not allowed. | |
| 2. | 1/8 inch lip (or dent) parallel to direction of vehicular travel. | |
| 3. | Taper ground areas from the lane/shoulder line into the shoulder area at 1/4 inch per foot. | |
| D. | Performance: | |
| 1. | Skid resistance of final ground surface must be comparable to adjacent sections not requiring corrective work. | |
| 2. | Surface treatement of ground areas. | |
| a. | Asphalt Concrete: Asphalt tack coat and sand blotter, Section 32 12 14. | |
| 3. | Waste grindings legally. | |
