HEAVY TRAFFIC MAINTAINED ON NIGHT PAVING PROJECT

CAREFUL PLANNING BY THE KENTUCKY DEPARTMENT OF HIGHWAYS, AND BY THE PRIME CONTRACTOR, MADE IT POSSIBLE TO RESURFACE THE HEAVILY-TRAVELLED EXPRESSWAY IN LOUISVILLE, KENTUCKY, BY PLACING HOT-MIX ASPHALT ON THE TEN MILE PROJECT DURING DARKNESS. A 6,000-8,500 POUND BATCH PLANT AND FOUR ASPHALT PAVERS WERE USED. ARMY SURPLUS GENERATORS WERE MOUNTED ON EACH PIECE OF EQUIPMENT TO PROVIDE ELECTRICITY FOR EXTRA LIGHTING. POLE-MOUNTED CLUSTERS OF LIGHTS WERE USED AT THE HOT-MIX PLANT, AND MASTS OF LIGHTS WERE PUT ON THE PAVER AND THE ROLLERS HAD STREET LIGHT INTENSITY MERCURY LIGHTS MOUNTED IN FRONT AND TWO MASTS WITH CLUSTERS OF FIVE 150-WATT LIGHTS IN THE BACK. TRAFFIC TRANSMISSION TO ONE LANE AT PAVING SITES WAS DAYLIGHTED BY CLUSTERS OF FOUR MERCURY LIGHTS POWERED BY DIESEL DRIVEN GENERATORS. TRAFFIC DIVERSIONS AND WORK-SITES WERE CLEARLY BOUNDED AND MADE VISIBLE TO THE NIGHT TIME DRIVERS BY THIRTY INCH HIGH TRAFFIC CONES THAT WERE REFLECTORIZED ON THE UPPER EIGHT INCHES. THE HOT-MIX PLANT TURNED OUT AN AVERAGE OF 150 TONS PER HOUR, FEEDING THE HAUL TRUCKS FOR THEIR 15-MILE JOURNEY TO THE PROJECT. THE THIRTY-SEVEN FEET, DIRT TO DIRT WIDTH, THAT INCLUDED THREE FEET OF INSIDE SHOULDERING, THE ROADWAY, AND TEN FEET OF OUTSIDE SHOULDER, WAS LAID DOWN IN THREE PASSES WITH THE PAVERS. TOLERANCES WERE ONE QUARTER OF AN INCH ON THE BINDER AND ONE EIGHTH INCH ON THE SURFACE COURSE. TEN TO TWELVE TON THREE-WHEEL AND TANDEM ROLLERS COMPACTED THE MAT. TWO-THIRDS OF THE CONTRACT WAS COMPLETED AHEAD OF SCHEDULE BEFORE SEASONAL SHUTDOWNS LAST NOVEMBER 15.
