SOMETHING NEW ON THE E4 HIGHWAY

CONSTRUCTION PRACTICES BEING USED ON THE SWEDISH E4 HIGHWAY JUST SOUTH OF STOCKHOLM ARE REVIEWED. BECAUSE OF THE POOR NATURE OF THE CLAY SOIL, A CONSIDERABLE AMOUNT OF LECK IS USED FOR THE EMBANKMENTS. THIS LIGHTWEIGHT MATERIAL HELPS TO PREVENT EXCESSIVE SETTLEMENT. IT IS GENERALLY PLACED IN A LAYER 50 CM THICK, TOPPED WITH 30 CM OF GRAVEL AND COMPACTED BY 3-4 TON TRACTOR-DRAWN VIBRATING ROLLERS MAKING SIX PASSES. AFTER THE BASE COURSE IS PUT DOWN IT IS COVERED WITH A LAYER OF FINES AND A WATER TRUCK SPRINKLES IT DOWN. THE TANKER USES DETERGENTS IN THE WATER TO GIVE THE WATER 2 TO 3 TIMES MORE COVERAGE. THE CONTRACTOR IS USING A BARBER-GREENE SR40 PAVER, A 10-TON STATIC ROLLER AND A 10-TON VIBRATING ROLLER. A LAYER OF PAPER IS SPREAD BETWEEN EACH LAYER OF ASPHALT AT THE CUT OFF POINT EACH DAY. THE NEXT DAY, BEFORE LAYING IS RECOMMENCED, THE MEN CUT ACROSS THE WIDTH OF THE ROAD WITH A COBRA PETROL-POWERED PAVEMENT BREAKER AND ROLL THE LAYERS BACK CLEANLY. THIS MAKES FOR SMOOTH TRANSITIONARY SURFACE AND GOOD ADHESION BETWEEN ADJACENT SECTIONS. THE CONTRACTORS LAY ABOUT 500 TONS OF ASPHALT PER 11-12 HOUR DAY. THE ASPHALT HAULERS HAVE ONE RATE OF PAY FOR THE RUN TO THE SITE, AND A LOWER RATE FOR THE EMPTY RUN BACK TO THE PLANT. THE IDEA IS TO ENCOURAGE A HASTY RETURN.
