EXPLOSIVES ELIMINATE A HIGHWAY HAZARD

DETONATING CORD (PRIMACORD) IS BEING USED IN MINNESOTA TO BREAK AWAY INTEGRAL LIP CUBS FOUR INCHES HIGH, WHICH WERE A PART OF THE TYPICAL CROSS-SECTION OF CONCRETE PAVEMENTS BUILT IN THE 1920'S AND UP UNTIL 1936. THE CONTRACTOR EMPLOYS A GRADER TO CUT A SHALLOW TRENCH TO RECEIVE THE BLASTING CORD, WHICH IS UNROLLED BY HAND. ASSUMING THAT A CABLE BURYING MACHINE SUCH AS IS USED BY THE TELEPHONE COMPANY IS USED ON FUTURE PROJECTS, IT IS ESTIMATED THAT APPROXIMATELY 1,000 FEET OF LIP CURB PER HOUR CAN BE REMOVED AT A UNIT COST OF APPROXIMATELY $0.164. /AUTHOR/
