Title: GRANULAR STABILIZED BASE CONSTRUCTION OF ACCESS AND RELOCATION ROADS BY TENNESSEE VALLEY AUTHORITY
Accession Number: 00231451
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: THE EXPERIENCE OF THE TENNESSEE VALLEY AUTHORITY IN THE CONSTRUCTION OF GRANULAR STABILIZED BASE COARSE IS OUTLINED. THE AUTHORITY HAS CONSTRUCTED APPROXIMATELY 128 MILES OF GRANULAR STABILIZED BASE COURSE, OF WHICH 47.5 MILES HAVE BEEN ACCESS ROADS AND 80.7 MILES RELOCATIONS. CALCIUM CHLORIDE HAS BEEN USED IN THE PROPORTION OF ONE LB. PER SQ. YD. PER 3-IN. COMPACTED LAYER. IT HAS BEEN FOUND EFFECTIVE IN INCREASING COMPACTED DENSITY, HOLDING MOISTURE AND INCREASING BONDS. THE MAINTENANCE COST ON THE COMPLETED SURFACE HAS BEEN EXTREMELY LOW AND HAS AVERAGED LESS THAN $100 PER MILE PER YEAR. THE PERFORMANCE OF THE CRUSHED STONE STABILIZED BASE HAS BEEN CONSIDERABLY BETTER THAN THAT OF THE GRAVEL BASE. STABILIZED GRANULAR BASE COURSES WITH LIGHT BITUMINOUS SURFACES WERE USED TO PROVIDE ACCESS TO 11 DAMS. THE TRAFFIC ON THESE ACCESS ROADS HAS AVERAGED FROM 1,000 TO 1,500 VEHICLES PER DAY FOR PERIODS FROM 2 YEARS TO 5 YEARS. STABILIZED GRANULAR BASE AND LIGHT BITUMINOUS SURFACING HAVE ALSO BEEN USED BY THE AUTHORITY ON BOTH STATE AND COUNTY HIGHWAY RELOCATIONS ON ROADS CONSTRUCTED TO REPLACE EXISTING ROADS THAT WERE FLOODED BY THE VARIOUS RESERVOIRS. THICKNESSES ARE DISCUSSED OF THE STABILIZED BASES. COSTS OF THE STABILIZED BASE CONSTRUCTION ARE DESCRIBED.
