LONGITUDINAL AND TRANSVERSE CONTROL FOR BITUMINOUS PAVERS

PROJECTS AMOUNTING TO APPROXIMATELY 67 MILES OF ASPHALTIC CONCRETE ON NEW BASE, 92 MILES OF ASPHALTIC CONCRETE OVERLAY ON OLD SURFACE, AND 277 MILES OF BITUMINOUS MAT OVERLAY ON OLD SURFACE WERE PLACED UNDER CONTRACT IN KANSAS DURING 1958. THE MATERIALS FOR THESE PROJECTS WERE MIXED IN HOT-MIX PLANTS AND PLACED ON THE ROAD THROUGH BITUMINOUS PAVERS. BECAUSE OF THE LIMIT WHICH BITUMINOUS PAVERS CAN LEVEL OR SMOOTH A ROAD SURFACE, THE PROBLEM OF PLACING THE MIXTURE TO A SMOOTH GRADE LINE WITH A TRUE CROWN CONFRONTS BOTH THE ENGINEER AND THE CONTRACTOR ON EACH PROJECT, PARTICULARLY ON OVERLAYS. WITH MODERN HIGH-SPEED TRAFFIC A SMOOTH GRADE LINE AND TRUE CROWN ARE MUSTS IN PAVEMENT CONSTRUCTION. THE DEVELOPMENT OF TWO ATTACHMENTS IS DESCRIBED THAT HAVE BEEN PLACED ON THE LEADING MAKES OF BITUMINOUS PAVERS AND HAVE BEEN SUCCESSFUL IN AIDING THE OPERATORS TO CAUSE THE PAVER SCREEDS TO FOLLOW A SMOOTH THEORETICAL GRADE LINE WITH A DEFINITE UNIFORM CROWN. THIS METHOD OF PAVING REQUIRES SEVERAL NORMAL OPERATIONS, SUCH AS ASCERTAINING A NEW GRADE LINE FROM THE ORIGINAL PROFILE AND THE USE OF PNEUMATIC- TIRED ROLLERS FOR COMPACTION. THIS METHOD OF PAVING REQUIRES LESS OVER-ALL WORK ON THE PART OF THE CONTRACTOR, BECAUSE THE SKIN PATCHING IN ALL CASES CAN BE REDUCED, AND IN SOME CASES ELIMINATED. /AUTHOR/
