Submit the Safety Data Sheet (SDS) for detergents or chemicals in the rubber and paint removal process. Use of any detergents or chemicals in the rubber and paint removal process must be approved in advance by the Contracting Officer. The Government specifically reserves the right to reject the use of any process which the Contracting Officer determines may pose unnecessary risks to human health, the environment, the pavement, aircraft or navigational aids due to corrosion or foreign object damage (FOD) potential as a result of its use, storage, or disposal.

PART 3 - EXECUTION

The Contracting Officer's Representative, the airfield manager and the pavements engineer will jointly develop guidelines and requirements for rubber and paint removal operations; and will jointly evaluate the feasibility of the Contractor's methods and project compliance with applicable regulations.

3.1 RUBBER AND PAINT REMOVAL

The following recommended rubber and paint removal percentages are based on visual estimation of pavement area required to be exposed by the removal process. The degree of removal possible without damaging the pavement surface will depend on pavement condition. Portland cement concrete pavements can withstand more water pressure impact than asphaltic concrete pavements before aggregates are exposed. It is not specified 100 percent removal, as this will result in excessive exposure of pavement aggregates.

Prior to any work being completed, submit a Rubber and Paint Removal Process Plan for approval by the Contracting Officer.

a. The pavement surface type is Portland cement concrete and asphalt mixture.

b. Remove 90 percent of all visible rubber on portland cement concrete pavements and 85 percent of all visible rubber on asphaltic concrete pavements. Remove 85 percent of paint on portland cement and asphaltic concrete pavement. Remove all paint that is loose, flaking, chalky, or not to be re-marked or does not comply with size or pattern standards.

c. Chemical methods used must be compatible with pavement materials, the environment and working personnel.

d. Exercise close control of water pressure and blasting time/duration to prevent damage to joints, existing markings that are not intended for removal, or the wearing surface. Neither hydroblasting or abrasive blasting may be used for rubber removal on porous friction courses.

e. Demonstrate the ability to remove rubber at a touchdown area of the runway selected by the Contracting Officer. Rubber removal must not damage the pavement surface. The surface texture of the cleaned demonstration area will be compared to that of non-rubber traffic areas to determine satisfactory completion of the removal operation.

f. After approval of the Contractor's operations by the Contracting Officer, the cleaned sample area will become the standard for rubber removal and final surface texture for the remainder of work.

g. Compliance testing for the amount of rubber and paint to be removed must conform to the requirements in paragraph COMPLIANCE TESTING.

3.2 RATE OF REMOVAL

Remove rubber at a minimum rate of 929 square meter per hour. Remove paint at a minimum rate of 93 square meter per hour. Do not permit high-pressure water application to remove the existing pavement surface, joint seals or crack seals.

3.3 WATER PRESSURE

The optimum water pressure to be used for rubber and paint removal will be determined by the test specified in paragraph entitled "Rubber and Paint Removal.".

Provide water pressure impact upon the indicated pavement areas sufficient to remove the designated rubber and paint to the required degree of removal without damaging the existing pavement, joint sealant, or other airfield appurtenances. The Contractor is responsible for repairing any damage caused by the removal work.

3.4 CLEANUP AND WASTE MANAGEMENT

Keep the worksite clean of by-products, debris and waste from rubber and paint removal operations. Perform cleanup operations continuously. Remove all residue from the pavement.

Obtain the approval of residue removal and management method from the Contracting Officer prior to beginning work. Submit a Waste Management Plan describing proposed actions regarding waste identification, segregation, packaging, temporary storage, valorization, disposal, collection, transport, recycling, reuse, treatment and final storage to the Contracting Officer's Representative for approval prior to the start of work. The plan will address management methods and requirements for hazardous and non-hazardous wastes.

3.5 COMPLIANCE TESTING

a. Compliance with the rubber and paint removal requirements must be determined by direct testing within the designated work area.

b. Use a 0.1 square meter section of transparent material inscribed with a grid of 100 equal squares as a tool for quantitative measure of the percent removal. Place the grid pattern on the pavement surface at random locations. Then count the squares which contain rubber and/or paint deposits. The number of squares containing rubber and/or paint deposits must not exceed the allowed percentage in each of the randomly selected locations.

c. Divide each work area designated for rubber and paint removal into at least four equal zones for the purpose of compliance testing. The layout of each zone must be approved by the Contracting Officer. Within each zone, a minimum of seven random locations must be evaluated. The amount of rubber and paint removed at each of the randomly selected test locations within each zone must meet the requirement described in paragraph RUBBER AND PAINT REMOVAL. Evaluate each zone independently. A zone not meeting the required percentage must be recleaned by the Contractor at the Contractor's expense.

d. Deposits of rubber or rubber buildup and paint are defined as any surface deposit that can be removed by scratching the deposit with a flat sharp object (such as a pocket knife) without damaging the pavement surface. Stains are defined as materials in the pavement surface microtexture that cannot be removed without damaging the pavement surface.

Stain is generally embedded in the surface of the pavement below the horizontal plane of the surface texture. The Contractor is not responsible for stain removal.
