TECHNIQUES IN SLIPFORM PAVING AND CONTINUOUSLY REINFORCED CONCRETE PAVEMENT CONSTRUCTION

CURRENT TECHNIQUES FOR SLIPFORM PAVING AND FOR INSTALLING REINFORCING STEEL IN CONTINUOUSLY REINFORCED CONCRETE PAVEMENT CONSTRUCTED BY SLIPFORMING ARE EXAMINED. IN PERFORMING THE STUDY, CONTACTS WERE MADE WITH VARIOUS HIGHWAY OFFICIALS, CONTRACTORS, EQUIPMENT MANUFACTURERS AND PRIVATE INDIVIDUALS. THE INFORMATION THUS OBTAINED INCLUDED DESCRIPTIVE LITERATURE, PHOTOGRAPHS, AND TIME-LAPSE MOVIES OF THE CONSTRUCTION OPERATIONS. THE REPORT IS DIVIDED INTO FOUR MAJOR PARTS. THE FIRST OF THESE REVIEWS THE DEVELOPMENTS, ACCEPTANCE, AND USAGE OF THE SLIPFORM PAVING TECHNIQUE. IT ALSO DISCUSSES ANCILLARY HIGHWAY PAVING ACTIVITIES, OTHER THAN THE CONSTRUCTION OF THE PRIMARY TRAFFIC-SUPPORTING PAVEMENT, WHERE SLIPFORM PAVING TECHNIQUES HAVE PROVED APPLICABLE. PROCEDURES FOR CHECKING THE PAVEMENT DEPTH AND TEXTURING AND MEASURING THE SURFACE SMOOTHNESS OF A SLIPFORMED PAVEMENT ARE ALSO DISCUSSED. THE SECOND PART DESCRIBES THE VARIOUS METHODS FOR INSTALLING BOTH MESH AND REBARS FOR CRC PAVEMENTS. IT INCLUDES A REVIEW OF THE EXPERIENCES OF THE SEVERAL STATES IN WHICH THESE TECHNIQUES HAVE BEEN USED, BASED ON INFORMATION FROM A QUESTIONNAIRE AND FROM TELEPHONE CONVERSATIONS. THE THIRD SECTION OF THE REPORT DESCRIBES EIGHT FIELD STUDIES WHICH WERE MADE DURING THE SUMMER OF 1970 IN FIVE DIFFERENT STATES. THESE OBSERVATIONS WERE RECORDED BY TIME-LAPSE PHOTOGRAPHY. A DESCRIPTION OF THE TIME-LAPSE TECHNIQUE AND THE MANNER IN WHICH IT WAS APPLIED TO THIS STUDY IS ALSO PROVIDED. THE FOURTH PART CONSISTS OF AN EVALUATION OF THE FINDINGS AND THE CONCLUSIONS DRAWN THEREFROM. THIS PART ALSO INCLUDES RECOMMENDATIONS FOR ACTION AND FOR FURTHER STUDY. /AUTHOR/
