8、.1.2 PaymentRubber removal will be paid for at the contract unit price per square meter foot of runway rubber removed.SECTION 32 01 11.52 Page 2Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1.2 SYSTEM DESCRIPTION1.2.1 RUBBER REMOVAL EQUIPMENTMechan
9、ical rubber removal equipment includes waterblasting, shotblasting, sandblasting, or other approved nonchemical systems. Control equipment to be used on asphalt or tar concrete to remove rubber accumulations and minimize disturbance to asphalt or tar mixtures. Equipment to be used on portland cement
10、 concretes shall be controlled to remove rubber accumulations and prevent removal of hardened paste from the concrete. Basic hand tools and the following major types of mechanical equipment will be considered acceptable for this project.1.2.1.1 Waterblasting EquipmentProvide mobile waterblasting equ
11、ipment capable of producing a pressurized stream of water that will effectively remove rubber from the pavement surface without significantly damaging the pavement. Regulate water pressure so that substantially all rubber accumulations are removed during execution of the work.1.2.1.2 Shotblasting Eq
12、uipmentProvide mobile self propelled shotblasting equipment capable of producing an adjustable depth of rubber removal and of propelling abrasive particles at high velocities on the rubber for effective removal. Each unit shall be self cleaning and self contained. Provide equipment able to confine t
13、he abrasive, any dust that is produced, and removed rubber; and capable of recycling the abrasive for reuse.1.2.1.3 Sandblasting EquipmentProvide mobile sandblasting equipment capable of producing a pressurized stream of sand and air that will effectively remove rubber from the pavement surface with
14、out filling voids with debris in asphalt or tar pavements or removing joint sealants in portland cement concrete pavements. Include with the equipment an air compressor, hoses, and nozzles of adequate size and capacity for removing all rubber. Equip the compressor with traps that will maintain the c
15、ompressed air free of oil and water, and capable of furnishing a flow rate of at least 0.071 cubic meters/second 150 cubic feet/minute of air at a pressure of at least 621 kPa90 psi at each nozzle.1.2.2 Chemical Rubber Removal EquipmentChemical equipment shall be capable of application and removal o
16、f chemicals from the pavement surface and shall leave only non-toxic biodegradable residue.1.3 SUBMITTALS*NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals shoul

Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval o
19、n Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Divisi

Neither equipment nor perso
24、nnel shall use any portion of an airfield without permission of these officers unless the runway is closed. In all cases, maintain verbal communication with the control tower before and during work in the vicinity of the airfield. The control tower shall be advised when work is completed. Runways wi
25、ll be closed during the following times:SECTION 32 01 11.52 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Day or Runway Runway ImportantDate Closing Time Opening Time Notes_ _ _ _1.4.2 Landing and Take-OffsEmergency landings and take-offs sha
26、ll take precedence over all Contractor operations. When notified of an emergency situation, cease all rubber removal operations and immediately clear the runway of all equipment and personnel for a distance of at least 60 meters 200 feet from the edge of the runway.1.5 DELIVERY, STORAGE, AND HANDLIN
27、GDeliver materials, that are required in the approved rubber removal process, in original manufacturers containers labeled with appropriate EPA, OSHA, or other agency warnings, if applicable. Protect materials from the environment until their use is required during execution of the work.1.6 ENVIRONM
28、ENTAL REQUIREMENTSPavement surface shall be free of snow, ice or slush. Surface temperature shall be at least 5 degrees C 40 degrees F and rising at the beginning of operations except those involving shotblasting or sandblasting for which a lower surface temperature may be approved. Cease operation
29、during thunderstorms. Cease operation during rainfall except for waterblasting and removal of previously applied chemicals. Cease waterblasting where surface water accumulation alters the effectiveness of material removal.PART 2 PRODUCTS (Not Applicable)PART 3 EXECUTION*NOTE: The Contracting Officer
30、, the airport administrator and the pavements engineer will jointly develop guidelines and requirements for rubber removal operations; and will jointly evaluate the feasibility of the Contractors methods and project compliance with applicable regulations.*3.1 RUBBER REMOVALThe pavement surface may b
31、e of portland cement, tar or asphalt mixtures. Only use chemical methods which are compatible with pavement materials, the environment and working personnel. Exercise close control of water pressure and blasting time/duration to prevent disintegration damage to asphalt and tar concretes. Exercise ex
32、tremely good control for porous friction courses. Demonstrate the ability to remove rubber at a touchdown area of the runway selected by the Contracting Officer; at least one site per runway will be chosen. Rubber removal shall be as complete as possible without damage to the pavement surface. The s
33、urface texture of the cleaned demonstration area will be compared to that of nonrubber traffic areas to determine satisfactory completion of the removal operation. After approval of the Contractors operations the cleaned area will become the standard for rubber removal and final surface texture for
34、the remainder of work.SECTION 32 01 11.52 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.2 CLEANUP AND WASTE DISPOSALKeep the worksite clean of debris and waste from rubber removal operations.
