REPORT OF SUBCOMMITTEE ON SLOPE EROSION

PERHAPS THE OUTSTANDING ACHIEVEMENT OF THIS DECADE IN THE SOLVING OF HIGHWAY SOIL EROSION PROBLEMS IS THE "STREAMLINING" OF THE HIGHWAY CROSS SECTION. THE OLD TYPE RAILROAD CROSS SECTION SO PREVALENT IN EARLIER HIGHWAY CONSTRUCTION PRACTICE HAS BEEN REPLACED BY A MORE FUNCTIONAL DESIGN, WITH EARTH SLOPES FLATTENED AND ROUNDED TO FIT LOCAL CONDITIONS OF SOIL AND TOPOGRAPHY. WELL FLATTENED AND ROUNDED EARTHWORK CROSS SECTIONS HAVE REDUCED CONSTRUCTION AND MAINTENANCE COSTS BECAUSE THEY FACILITATE THE USE OF MOTORIZED GRADING, MOWING AND SNOW REMOVAL EQUIPMENT. THE IMPROVED CROSS SECTION REDUCES GUARD RAIL REQUIREMENTS ON FILLS AND MAKES FOR A SAFER AND MORE ATTRACTIVE HIGHWAY, BLENDING THE ROADSIDE INTO THE ADJACENT COUNTRYSIDE. /AUTHOR/
