FOUR CORNERS AREA-STUDY OF SUBGRADE CONSTRUCTION WITHOUT MOISTURE-DENSITY CONTRACT

THIS PROJECT WAS ESTABLISHED TO SUPPLY INFORMATION AS TO THE EVENTUAL CONDITION OF FILLS AND CUTS CONSTRUCTED IN ARID REGIONS OF COLORADO WITHOUT MOISTURE OR DENSITY CONTROL. THIN-WALL PIPES HAVE BEEN PLACED IN CERTAIN FILLS FOR STUDIES OF MOISTURE AND DENSITY WITHNUCLEAR PROBES. INITIAL MOISTURE-DENSITY VALUES WERE DETERMINED BY CONVENTIONAL METHODS FROM THE INSIDE OF 36 INCH DIAMETER DRILLED DEEP INTO THE FILLS. DURING THIS PERIOD, THE DEPARTMENT OF HIGHWAYS, STATE OF COLORADO PUT UNDER CONTRACT TWO ADDITIONAL PROJECTS THAT DID NOT REQUIRE MOISTURE AND DENSITY CONTROL. THESE PROJECTS WERE' /1/ S 0022/2/, BROOMFIELD - SH 93, AND /2/ F 016-1/38/, TURKEY CREEK CANYON EAST. MOISTURE AND DENSITY DATA WERE GATHERED ON THESE PROJECTS DURING CONSTRUCTION SO THAT COMPARISONS COULD BE MADE WITH DATA OBTAINED FROM THE FOUR CORNERS PROJECT. DATA FROM A PREVIOUSLY CONSTRUCTED PROJECT BETWEEN LIMON AND AGATE IS ALSO QUITE COMPARABLE TO DATA FROM THE FOUR CORNERS AREA. /AUTHOR/
