Specifications include, but are not limited to: SECTION A – SURFACE PREPARATION SPECIFICATIONS 1) All asphalt surfaces are to be thoroughly cleaned. 2) All asphalt surfaces must be free from all dirt, dust, debris, and chemical residues. 3) Grass is to be excavated and removed along the edges of pavement to find the true edge of pavement. 4) Asphalt surfaces that are embedded with hardened accumulations of grease, gum, hard clay, dust, silt, and any other foreign matter that cannot be removed by mechanical means, must be pressure washed. 5) Wipe, scrape, or burn excessive buildup of oil, grease, and gasoline spots. 6) Deeply impregnated oil or other petroleum products, may need a manufacture recommended primer or sealer applied before other asphalt work, as specified in this bid, is to take place. 7) All surfaces must be dry before any work is to be done. 8) All dirt, debris, and contaminates are to be removed from the site by the contractor. 9) Any excavated area with slopes or grades requiring erosion control will be seeded with Bermuda grass and have properly staked biodegradable erosion control blanket put in place. 10) All storm drain inlets are to be protected so as not to allow any debris, waste water, material/product spillage, or contaminated run-off, to enter any storm drainage systems. SECTION B – FULL DEPTH ASPHALT REPAIR SPECIFICATIONS 1) Areas to receive full depth repairs are shown on included drawings with this bid. 2) Standard duty asphalt is for walking paths, athletic courts, play pads, and parking lots. A drawing for standard duty asphalt specifications is included with this bid. 3) Heavy duty asphalt is for bus loops, dock receiving areas, drives/car loops, and trash dumpster areas. A drawing for heavy duty asphalt specifications is included with this bid. 4) Cut edges of damaged areas by mechanical means. Saw cutting is permitted. No skip/wheel cutting or jackhammering will be allowed. 5) Corners of repair areas shall be at right angles. 6) Excavate material in a manner that will protect the asphalt that will remain. Asphalt that is damaged will be repaired by the contractor at their sole expense. 7) Remove existing pavement that has failed. 8) Repair in accordance with the Standard or Heavy duty specified drawings that are included. This will be determined by location and function. See 1) and 2) of this section. 9) If asphalt damage is determined to be caused by tree roots or other organic matter, remove all roots 2’ feet beyond the damaged area and construct back according to included drawings and specifications. 10) Wet, damaged, or unsatisfactory sub-grade material shall be removed and replaced with suitable material, not less than 6”. Proper base material is to be added and compacted to 96%. 11) If suitable subgrade is found, repair according to methods listed below. 12) Prime/apply to all areas of repair, including bottom and all sides with asphalt binder/tack coat. 13) Fill and compact in suggested lifts, hot mix asphalt. Compact with vibratory-plate compactor or mechanical asphalt roller. 14) Final repair shall be flush and level with adjoining surfaces. 15) If any seems are visible between repair and adjoining surfaces, see crack sealing specifications. 16) Contractor will use steel plates at the end of the day for any areas left that are excavated to a depth of 2” inches or greater. Steel plates will withstand traffic loading without movement, meet ASTM A 36, anchored securely to prevent movement, and to resist bending, vibrations, etc. under traffic. 1) METHOD 1 - “3+3” FDR of small areas (potholes) a. Cut out area around damaged pavement as a clean rectangle. b. Excavate subgrade underneath to a depth 6" below pavement surface. Dispose of all debris off-site. c. Compact remaining subgrade with motorized tamp. d. Add 3-inch layer of crusher-run gravel, and compact with tamp again. e. Apply tack coat to pavement edges, and allow to dry. f. Pave area at 3-inch depth using type C surface asphalt. g. Roll new asphalt flush with existing pavement. h. Sweep work area clean. 2) METHOD 2 - “4+4” FDR of areas requiring heavy duty asphalt or failed base layer a. Cut out area around damaged pavement as a clean rectangle. b. Excavate subgrade underneath to a depth 8" below pavement surface. Dispose of all debris off-site. c. Compact remaining subgrade with motorized tamp. d. Add 4-inch layer of crusher-run gravel, and compact with tamp again. e. Apply tack coat to pavement edges, and allow to dry. f. Pave area at 4-inch depth using type C surface asphalt. g. Roll new asphalt flush with existing pavement. h. Sweep work area clean. 3) METHOD 3 - “Blade and roll” FDR of large areas (greater than 10’ x10’) a. Cut out pavement around each damaged area as marked. b. Remove any soft material from subgrade. c. Dispose of all debris off-site. d. Add new crusher-run gravel as needed, then aerate existing subgrade using tined bucket on skid-steer tractor. e. Compact gravel subgrade with motorized tamp. f. Apply tack coat to pavement edges, and allow to dry. g. Determine if area requires standard duty or heavy-duty asphalt h. Pave areas at full original depth using type C surface asphalt (large patches in driveway will be paved at a depth of 4 inches). i. Roll new asphalt flush with existing pavement. j. Sweep work area clean
