6、ation are manufac-tured in sheet form to a range of thicknesses:14in.,38in.,12in.,34in.,and 1 in.Sheet sizes may be 3 or 4 ft in width andlengths of 3,5,6,10,or 12 ft.Purchaser must specify sheetsizes when ordering(excluding Type IVRecycled PVC).3.2 Joint filler in strip form is cut from the sheets
7、asmanufactured.When ordering joint filler strips the purchasermust specify thickness,widths,and length;strip widths areavailable from 2 in.(50 mm)in increments of12in.(13 mm).3.3 Type IV joint filler is available in strip form,cut fromthe sheets as manufactured,and available in a range ofthicknesses
8、:14in.,38in.,12in.,or34in.When ordering jointfiller strips,the purchaser must specify thickness,widths,andlength;strip widths are available from 2 in.(50 mm)inincrements of12in.(13 mm).4.Materials4.1 Sponge RubberThe joint filler shall consist of pre-formed strips of a durable,elastic sponge rubber
9、compound,using synthetic rubber or natural rubber as a base and contain-ing no reclaim rubber or factice.Unless otherwise specified,the sponge rubber shall have a cement gray color to blend withconcrete in appearance.4.2 Cork and Self-Expanding CorkThe joint filler shallconsist of preformed strips t
10、hat have been formed from cleangranulated cork particles securely bound together by a syn-thetic resin of an insoluble nature.4.3 Recycled PVCThe joint filler shall consist of pre-formed strips that have been extruded using scrap PVCmaterial and using either no binder or a synthetic resin of aninsol
11、uble nature to securely bind it together.Unless otherwisespecified,the recycled PVC should have a cement gray color toblend with concrete in appearance.4.4 Preformed strips of expansion joint fillers shall be ofsuch character as not to be deformed or broken by ordinaryhandling when exposed to atmosp
