THE USE OF SLURRY SEAL FOR PAVEMENT MAINTENANCE

SLURRY SEAL IS THE MOST ECONOMIC AND RATIONAL PROCESS FOR MAINTENANCE OF BITUMINOUS PAVEMENTS. THE USES OF THIS BITUMINOUS MIXTURE RESULTING FROM NATIONAL AND INTERNATIONAL EXPERIMENTS ARE PRESENTED WITH SPECIAL EMPHASIS ON THE FIRST PRACTICAL EXPERIMENT CARRIED OUT IN THE STATE OF PARANA. THE TECHNICAL ELEMENTS AND COMMENTS ON THE EXPERIMENTS, INCLUDING THE DIFFICULTIES MET DURING THE WORKS, ARE ALSO PRESENTED. A COST SURVEY OF BITUMINOUS MIXTURES IN THE LOCAL MARKET WAS ALSO MADE. SLURRY SEAL HAS PROVED CONSIDERABLY MORE ECONOMICAL FOR THE MAINTENANCE OF PAVEMENTS WHEREVER IT HAS BEEN APPLIED. IT IS CAPABLE OF EXTENDING THE SERVICE TIME OF THE PAVEMENTS WHOSE INFRASTRUCTURE ARE IN SATISFACTORY CONDITION. HOWEVER, THE IMPORTANCE OF PERMANENT CHECKING OF THE PAVEMENT IS STRESSED IN ORDER TO ALLOW TIME FOR NECESSARY PRECAUTIONS TO BE TAKEN BEFORE IT GOES INTO A PLASTIC STATE TO PREVENT THE TOTAL COLLAPSE OF THE PAVEMENT. /RRL/
