Title: ASPHALTIC BINDER STABILIZED ROADS
Accession Number: 00232918
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: SOIL STABILIZATION IS "THE TREATMENT OF SOILS WITH ADMIXTURES WHICH EITHER INTRODUCE OR INCREASE A CERTAIN STABILITY ELEMENT (GRAVEL AND SAND FOR FRICTION AND INTER- LOCKING ACTION) OR CHANGE THE SOIL AS A RESULT OF PHYSICO- CHEMICAL REACTION." THE PURPOSE OF THESE ADMIXTURES IS TO PROVIDE A SOIL SYSTEM WHICH IS STABLE UNDER ALL CLIMATIC CONDITIONS AND TRAFFIC. ONE OF THE SIMPLEST METHODS OF CHEMICAL STABILIZATION INVOLVES THE SURFACE APPLICATION OF ROAD OIL TO EARTH SURFACES AT A RATE OF APPROXIMATELY ONE GALLON PER SQUARE YARD, PREFERABLY IN TWO OR THREE INCREMENTS. THE SUBOILED METHOD INVOLVES THE USE OF A SUBOILING MACHINE THAT CONSISTS OF A 4 WHEELED TRACTOR-DRAWN A FRAME, 7 1/2 FT. WIDE, ON WHICH ARE MOUNTED 31 SCARIFIER TEETH. THE PURPOSE IS TO SPREAD THE GRANULAR MATERIAL, IF ANY IS TO BE ADDED, UNIFORMLY OVER THE ROADWAY SO THAT IT IS READY FOR STABILIZATION. THE SCARIFIED LAYER IS PULVERIZED TO THE POINT THAT ALL MATERIAL WILL PASS FREELY BETWEEN THE SUBOILER TEETH. THE BITUMINOUS TREATING AGENT IS INTRODUCED AT ONE OR MORE DEPTHS AS IS ALSO A PREDETERMINED QUANTITY OF WATER, EXCEPT FOR EMULSIONS. FOR THE ROAD MIX METHOD, ONE OF THE DIFFERENCES IS THAT THE BITUMINOUS TREATING AGENT IS APPLIED IN INCREMENTS 1/2 GAL. PER SQUARE YARD (FOR 5 TO 6 IN. BASE THICKNESS). EACH APPLICATION IS INCORPORATED WITH THE SOIL AGGREGATE MIXTURE, TOGETHER WITH A SUFFICIENT AMOUNT OF WATER, BY MEANS OF DISKS AND GANG PLOWS.
