PART 3 EXECUTION.

3.1 RUBBER AND PAINT REMOVAL.

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 as indicated.

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 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; at least one site per runway will be chosen. Rubber removal must not damage the pavement

SECTION 32 01 11.51 Page 6 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 10,000 square feet per hour. Remove paint at a minimum rate of 1,000 square feet per hour. Do not permit high-pressure water application to remove the existing pavement surface, joint seals or crack seals.

3.3 WATER PRESSURE.

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 DISPOSAL.

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

Submit a Waste Collection, Identification and Disposal Plan describing proposed actions regarding waste collection, control, identification, and disposal to the Contracting Officer's Representative for approval prior to the start of work. The plan will address disposal 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 one square foot 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.
