653.02 General Insulating material shall be extruded polystyr ene insulating board
conforming to the requirements of AASHTO M230. Pegs shall be hard wood, approximately 6 inches by ¼ inch roun d, pointed on one end.
653.03 Preparation of Foundation The insulating boards shall be placed on a
compacted layer of granular mater ial graded to a tolerance of ½ inch above or below the required grade and cross section. The surface shall be free of rocks that would cause damage to the insulating boards . The type and thickness of the granular material will be as shown on the plans.
653.04 Placing Insulating Boards The insulating boards shall be secured to the
ground with pegs placed at each corner or where directed by the Resident, and driven flush with the surface of the insul ating board. Joints between the i nsulating boards shall be staggered. The openings in all joint shall be kept to a minimu m.
653.05 Placing Backfill After the insulating boards have been placed, granular
material shall be placed using care to avoid pushing or punctur ing the boards. The depth of the first layer of aggregate subbase sand shall not be less tha n 10 inches loose measure. The aggregate subbase sand shall be spread with a crawler type bull dozer of not more than 2000 lb/ft² ground contact pressure or with other approved equipment but not supported directly on the insulating boards. Trucks and other heavy construction equipment shall not be operated directly on the insulating boards. The type and thick ness of granular material will be shown on the plans.
653.06 Compaction Compaction of the first layer of aggregate subbase sand shall be
by vibratory methods to the satisf action of the Resident. Afte r the first layer has been compacted, normal construction practices may be followed provid ing no loads are placed on the area that produce more than 2000 lb/ft² ground contact pres sure.
653.07 Protection of Polystyrene Since gasoline, oil, heat, a nd sunlight will damage
polystyrene, all precautions shall be taken to prevent them fro m damaging the insulating board. The insulating boards shall not be stored in sunlight f or more than one day.
653.08 Method of Measurement Polystyrene plastic insulation w ill be measured by
the square yard in place.
653.09 Basis of Payment The accepted quantities of polystyren e plastic insulation
will be paid for at the contract unit price per square yard com plete in place. Payment shall be full compensation for and for furnishing and placing the ins ulating boards of pegs. Payment will be made under: 6-164 Pay Item Pay Unit
