412.01 Description. This item shall consist of cold milling the
asphalt pavement at the location(s) designated on t he plans or by the Engineer and removing the resulting material from t he highway right-of-way. Unless otherwise provided, the recla imed pavement shall become the property of the Contractor. The p avement remaining after milling shall provide a surface sui table for maintaining traffic.
412.02 Equipment. The Contractor shall provide self-propelled
equipment with sufficient power, traction, and stab ility to maintain an accurate depth of cut and slope. The equipment shall be capable of accurately and automatically establishing profil e grades along each edge of the machine by referencing from the ex isting pavement by means of a ski or matching shoe or from an indep endent grade control and shall have an automatic system for cont rolling cross 297 slope at a given rate. The milling machine shall h ave an effective means for preventing dust resulting from the operat ion from escaping into the air. Provision shall be made, either integrally with the milling machine or by the use of additional equipment, to r emove the material being cut from the surface of the roadway.
412.03 Construction Requirements. The existing pavement
shall be cold milled to the depth shown on the plan s. The number of passes and the depth of each pass required to obtai n the total depth to be removed will be determined by the Contractor, unless specified in the plans. The transverse joint left at the end of each day's run shall be tapered to provide a smooth ride. When co ld milling asphalt pavement results in vertical differentials at the lane lines or at the edge of the traveled lanes, the Contractor s hall comply with the requirements of Subsection 603.02(d). At the e nd of a day’s run, vertical differentials will only be permitted at th e centerline or lane lines. The equipment shall be operated at a rate o f travel that will provide a surface meeting the applicable surface re quirements.
412.04 Method of Measurement. Cold Milling Asphalt
Pavement will be measured by the square yard (squar e meter) of pavement milled to the depth specified.
412.05 Basis of Payment. Work completed and accepted and
measured as provided above will be paid for at the contract unit price bid per square yard (square meter) for Cold M illing Asphalt Pavement, which price shall be full compensation fo r all work as prescribed herein, and for all labor, equipment, to ols, and incidentals necessary to complete the work. Payment will be made under: Pay Item Pay Unit Cold Milling Asphalt Pavement Square Yard (Square Meter) SECTION 413 VACANT 298 SECTION 414 ASPHALT CONCRETE PATCHING FOR MAINTENANCE OF TRAFFIC
