A STUDY OF WINTER MAINTENANCE OF BITUMINOUS PAVEMENTS IN TEXAS

WINTER MAINTENANCE OF FLEXIBLE PAVEMENTS IS STUDIED. THE SIGNIFICANT PROBLEM AREAS THAT WERE INVESTIGATED ARE: CRACK SEALING OPERATIONS, POT HOLE REPAIR; EDGE RAVELING; DEVELOP- MENT OF A SIMLIFIED TEST PROCEDURE FOR THE EVALUATION OF THE WORKABILITY STABILITY OF COLD MIXES; A PRELIMINARY LABORATORY INVESTIGATION OF THE WORKABILITY-STABILITY CHARACTERISTICS OF COMMERCIALLY AVAILABLE COLD MIXES; DEVELOPMENTAL RESEARCH WORK DIRECTED TOWARD THE UPGRADING OF WORKABILITY-STABILITY CHARACTERISTICS OF COLD MIXES; THE USE OF SURFACE ROLLING FOR A RESTORATION OF DENSITY AND STABILITY TO PAVEMENT EDGES AND SHOULDERS; A FIELD INVESTIGATION OF THE USE OF FIBER MAT FOR REINFORCING AND SEALING EXTENSIVE PATTERNS OF SURFACE CRACKING; A FURTHER INVESTIGATION OF THE USE OF A MAINTENANCE PAVER FOR THE APPLICATION OF COLD MIXES TO DISTRESSED AREAS; A FIELD INVESTIGATION OF SPECIAL SURFACE CRACKING PROBLEMS. RECOMMENDED IMPROVEMENTS IN WINTER MAINTENANCE OPERATIONS INCLUDED MORE EXTENSIVE USE OF MECHANIZED EQUIPMENT, IMPROVED QUALITY CONTROL OF PATCHING MATERIALS, AND CONSIDERATION OF PREVENTIVE MAINTENANCE AS A MEANS OF MINIMIZING REPAIRS DURING INCLEMENT WEATHER. /AUTHOR/
