RUNWAY RUBBER REMOVAL

08/08

PART 1 GENERAL

1.1 SYSTEM DESCRIPTION

1.1.1 RUBBER REMOVAL EQUIPMENT

Mechanical rubber removal equipment includes waterblasting or other approved nonchemical systems. Submit a list of construction equipment including item names and descriptions. 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 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.

1.1.1.1 Waterblasting Equipment

Provide mobile waterblasting equipment 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.

1.1.2 Chemical Rubber Removal Equipment

Chemical equipment shall be capable of application and removal of chemicals from the pavement surface and shall leave only non-toxic biodegradable residue.

1.2 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for information only. Submit the following in accordance with contract requirements:

SD-03 Product Data

Rubber Removal Equipment; G Rubber Removal; G

1.3 QUALITY ASSURANCE

1.3.1 Maintenance of Traffic

Coordinate the operation of equipment and the performance of work upon and in the vicinity of airfields with the Contracting Officer and with the Flight Operations Officer. Neither equipment nor personnel shall use any portion of an airfield without permission of these officers unless the runway is closed. In all cases, maintain verbal radio communication with

FA4418-16-R-0011

Attachment 5

Attachment 5 the control tower before and during work in the vicinity of the airfield.

The control tower shall be advised when work is completed.

1.3.2 Landing and Take-Offs

Emergency landings and take-offs shall 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 200 feet from the edge of the runway.

1.4 DELIVERY, STORAGE, AND HANDLING

Deliver materials, that are required in the approved rubber removal process, in original manufacturer's 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.

1.5 ENVIRONMENTAL REQUIREMENTS

Pavement surface shall be free of snow, ice or slush. Surface temperature shall be per manufacturer's written recommendations. Cease operation 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

3.1 RUBBER REMOVAL

The pavement surface may be of portland cement, tar or asphalt mixtures.

Submit statements regarding the suitability of materials, personnel, and methods proposed to accomplish the work. 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 extremely 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 surface 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 Contractor's operations the cleaned area will become the standard for rubber removal and final surface texture for the remainder of work.

3.2 CLEANUP AND WASTE DISPOSAL

Keep the worksite clean of debris and waste from rubber removal operations. Cleanup operations shall be continuous. Debris and waste materials shall be accumulated and disposed at approved sites.
