POLYETHYLENE JOINT RELIEF FILLER PROTECTS AGAINST BLOWUPS

THE ILLINOIS DIVISION OF HIGHWAYS IS USING A NEW TYPE OF PAVEMENT JOINT RELIEF FILLER MADE OF EXPANDED POLYETHYLENE FOAM TO PROTECT AGAINST COSTLY BLOW-UPS AND BRIDGE DAMAGE CASED BY PAVEMENT EXPANSION. CALLED "ETHAFOAM," THIS FILLER MATERIAL PROVIDES 75 PERCENT MORE COMPRESSIBILITY THAN PREVIOUSLY USED PREMOLDED FIBER OR FELT-TYPE FILLERS. AT A COMPRESSION OF 80 PERCENT, FOR EXAMPLE, THE MATERIAL TRANSMITS LESS THAN 125 PSI. THE MATERIAL ALSO HAS A WATER ABSORPTION RATE OF LESS THAN 0.5 PERCENT BY VOLUME AND A MOISTURE VAPOR PERMEABILITY RATE OF LESS THAN 0.4 INCH. IN TERMS OF JOINT REPLACEMENT, USE OF THE FILLER RESULTS IN SIGNIFICANT TIME AND COST SAVINGS. /AUTHOR/
