SOIL CONTROL IN CONSOLIDATED MAINTENANCE

THE MICHIGAN STATE HIGHWAY DEPARTMENT USES A UNIFORM MAINTENANCE PROCEDURE FOR THE CONSOLIDATION OF LOOSE FLOATING COVER ON THE GRAVEL TRUNKLINE SYSTEM, BASED ON THE ECONOMICAL USE OF LOCAL AGGREGATES AND BINDER SOILS. IN SOME CASES SPECIALIZED EQUIPMENT HAD TO BE DESIGNED BEFORE IT WAS FREE FROM THE HAZARDS OF DUST, LOOSE GRAVEL OR SLIPPERINESS CAUSED BY IMPROPER APPLICATIONS OF CLAY BINDER SOIL. THE DEVELOPMENT OF A UNIFORM SYSTEM OF REGIONAL MAINTENANCE REQUIRES KNOWLEDGE AND USE OF THE FOLLOWING FACTORS: (1) THE LOCATION OF SOURCES OF LOCAL MATERIALS NORMALLY USED IN STABILIZED AGGREGATE MIXTURES. (2) A SIMPLIFIED METHOD OF DESIGN WHICH PERMITS UNIFORM APPLICATION OF BINDER SOIL OR CORRECTIONS IN THE GRADINGS OF LOOSE SURFACING MATERIALS WHICH RESULT FROM WINTER MAINTENANCE OPERATIONS. (3) AGGREGATE SPECIFICATIONS FLEXIBLE ENOUGH TO PERMIT THE USE OF THE BETTER GRADES OF MATERIAL OCCURRING IN THE VICINITY OF THE ROAD SYSTEM YET RIGID ENOUGH TO INSURE THE PRODUCTION OF UNIFORMLY GRADED AGGREGATES FOR ROAD USE. (4) CENTRALIZED CONTROL FOR MAINTENANCE OPERATIONS WITH PERIODIC FIELD CHECKS FROM THE CENTRAL CONTROL POINT TO ENFORCE THE INSTRUCTIONS ISSUED TO THE VARIOUS SECTIONS OF THE STATE. /AUTHOR/
