PAVEMENT WIDENING AND RESURFACING IN IDAHO

MANY MILES OF ASPHALTIC AND PORTLAND-CEMENT CONCRETE PAVEMENTS WERE STRUCTURALLY INADEQUATE AND IN NEED OF IMMEDIATE RECONSTRUCTION IN IDAHO AT THE END OF WORLD WAR II. A PROGRAM OF WIDENING AND RESURFACING WAS INITIATED TO TAKE IMMEDIATE ACTION TO ACCOMMODATE TRAFFIC AND REDUCE MAINTENANCE COSTS. PROCEDURES USED FOR WIDENING AND RE-ENFORCING STRUCTURALLY INADEQUATE ASPHALTIC CONCRETE PAVEMENTS ARE ILLUSTRATED. PORTLAND-CEMENT CONCRETE PAVEMENTS THAT WERE STRUCTURALLY ADEQUATE WERE WIDENED AND RESURFACED AS SHOWN. ALL OF THE RESURFACING PROJECTS WERE GIVEN A SEAL COAT NOT SOONER THAN 10 DAYS AFTER LAYING THE PAVEMENT. CONSTRUCTION METHODS AND PERFORMANCE RESULTS ARE DISCUSSED. IT IS RECOMMENDED THAT THE ADDED BASE AND STABILIZED BASE BE COMPACTED EQUAL IN DENSITY TO THE EXISTING BASE AND PAVEMENT TO REDUCE GROOVING AND REFLECTIONS OF THE OLD PAVEMENT EDGE. IT IS SUGGESTED THAT BY USING BITUMINOUS STABILIZED BASE A DISTANCE OF ONE FOOT OR MORE OUTSIDE THE FINISHED PAVEMENT WOULD HELP REDUCE PAVEMENT EDGE REFLECTION CRACKS BY INCREASING THE EDGE SUPPORT. PAVING THE SHOULDER FULL WIDTH TO THE SAME THICK- NESS, AND WITH THE SAME MATERIAL AS THE PAVEMENT WOULD HELP. STABILIZING THE CRUSHED BASE WIDENING WITH PORTLAND CEMENT IS SUGGESTED TO ELIMINATE COMPACTION OF THE AGGREGATE BY TRAFFIC. STABILIZATION OF THE WIDENED BASE SHOULD BE FOR THE FULL DEPTH. PORTLAND-CEMENT CONCRETE PAVEMENTS SHOULD HAVE ALL ROCKING AND LOOSE SLABS MUD JACKED TO PREVENT MOVEMENT. IT WAS OBSERVED THAT A MINIMUM OF SIX INCHES OF CRUSHED GRAVEL BASE OVER THE OLD PAVEMENT IS REQUIRED IF REFLECTION CRACKS ARE TO BE ELIMINATED. A UNIFORMITY OF SECTION FULL WIDTH IS RECOMMENDED FOR GOOD RIDING QUALITY.
