PHYSIOGRAPHIC SUBDIVISION FOR ENGINEERING PURPOSES

PHYSIOGRAPHY PERMITS SUBDIVISION INTO AREAS OF CONTRASTING OR DISTINCTIVE TOPOGRAPHIC EXPRESSION. SUCH DIVISIONING IS EFFECTED BY AN EXAMINATION OF THREE GEOMETRIC CONTROL FACTORS: STRUCTURE, PROCESS AND STAGE. PHYSIOGRAPHIC STUDIES WERE MADE OF THE FOLLOWING SPECIFIC HIGHWAY ENGINEERING FACTORS: (1) AVAILABILITY AND PROBLEMS OF MINERAL AGGREGATES, (2) SURFICIAL SOIL DISTRIBUTION ON THE BASIS OF ORIGIN AND GENERALIZED TEXTURE, AND (3) RELATED SOIL PROBLEMS SUCH AS HIGH VOLUME CHANGE, FROST SUSCEPTIBILITY AND LANDSLIDE. THE SPECIFIC ENGINEERING PROBLEM DESCRIBED IS THE DISTRIBUTION OF CRUSHED AGGREGATES WITHIN THE PHYSIOGRAPHIC UNITS OF THE INTERIOR LOW PLATEAU PROVINCE. COGENT HIGHWAY ENGINEERING DESIGN AND CONSTRUCTION FACTORS CAN BE GENERALIZED WITH RESPECT TO PHYSIOGRAPHIC UNITS, WHICH MAY SERVE AS A GEOGRAPHIC FILING SYSTEM FOR ENGINEERING EXPERIENCES. A TABLE PRESENTS THE SUMMARY OF CRUSHED STONE AVAILABILITY WITHIN THE SUBSECTIONS OF THE INTERIOR LOW PLATEAUS PROVINCE.
