Asphalt solutions and methods for applying the same

Abstract

Abstract AN ASPHALT SOLUTION FOR TREATING UNCEMENTED SANDS, SOILS AND AGGREGATES TO CONSOLIDATE THE SAME, WHICH SOLUTION CONTAINS A LIGHT PETROLEUM OIL FRACTION HAVING A BOILING POINT LOWER THAN THAT OF LIGHT GAS OIL AND FROM 10-80% BY WEIGHT OF A GEL TYPE ASPHALT. THE GEL TYPE ASPHALT HAS AN R RATIO OF ABOUT 0.8 TO ABOUT 1.2 AND HAS A PENETRATION OF 60-100 AT 77*F. (ASTM D-5). THE ASPHALT SOLUTION CONTAINS A CATIONIC SURFACTANT AND THE SOLUTION HAS A 95% MINIMUM COATING RETENTION AS TESTED BY ASTM TEST D-1664. THE METHOD OF TREATING BODIES OF UNCEMENTED SAND, SOILS AND AGGREGATES TO CONSOLIDATE THEM, WHICH METHOD INVOLVES APPLYING TO THE SURFACE OF THE BODIES AN ASPHALT SOLUTION AS DEFINED ABOVE. THE METHOD OF TREATING BODIES OF UNCEMENTED SANDS, SOILS AND AGGREGATES TO CONSOLIDATE THEM. FIRST, THERE IS APPLIED TO THE SURFACE A SOLUTION OF A LIGHT PETROLEUM OIL FRACTION HAVING A BOILING POINT LOWER THAN THAT OF LIGHT GAS OIL AND CONTAINING FROM 10 TO 30% BY WEIGHT OF A GEL TYPE ASPHALT HAVING A PENETRATION OF 60-100 AT 77*F. (ASTM D-5), AND R RATIO OF FROM ABOUT 0.5 TO ABOUT 1.2, AND CONTAINING A CATIONIC SURFACTANT. THE SOLUTION HAS A 95% MINIMUM COATING RETENTION AS TESTED BY ASTM TEST D-1664 AT A RATE OF APPLICATION OF ABOUT 0.2 TO ABOUT 1 GALLON PER SQUARE YARD OF SURFACE BEING TREATED. FOLLOW- ING THE FIRST TREATMENT, THERE IS APPLIED TO THE SURFACE A LIGHT PETROLEUM OIL (AS DEFINED ABOVE) SOLUTION CONTAINING 50-70% BY WEIGHT OF A GEL TYPE ASPHALT HAVING A PENETRATION OF 60-100 AT 77*F. (ASTM D-5), AN R RATIO OF FROM ABOUT 0.8 TO ABOUT 1.2 AND CONTAINING A CATIONIC SURFACTANT. THE ASPHALT SOLUTION HAS A 95% MINIMUM COATING RETENTION AS MEASURED BY ASTM D-1664, AND THE SECOND APPLICATION IS MADE AT A RATE OF FROM ABOUT 0.5 TO ABOUT 2 GALLONS PER SQUARE YARD OF THE SURFACE BEING TREATED.
