UTAH'S PROBLEMS WITH SWELLING SOILS

THE MAJORITY OF UTAH'S PROBLEMS WITH SWELLING SOILS OCCURS IN THE MANCOS SHALE AREAS. TO DATE A PAVEMENT STRUCTURE WHICH WILL ADEQUATELY PREVENT OR SUPPRESS HEAVING TO A TOLERABLE LEVEL HAS NOT BEEN DESIGNED. PRESENTLY THERE ARE APPROXIMATELY 130 MILES OF STATE HIGHWAY AND 90 LANE MILES OF INTERSTATE THROUGH THE MACOS SHALE AREAS, AND IT IS EXPECTED THAT THERE WILL BE 80 MORE LANE MILES OF INTERSTATE CONSTRUCTED IN THE MANCOS SHALE. UTAH'S PROBLEM, THEREFORE, STEMS FROM THE FACT THAT A CONSIDERABLE MAINTENANCE BURDEN WILL RESULT IF THE SWELLING OF THE MANCOS SHALE CANNOT BE CONTROLLED BY ADEQUATE PAVEMENT STRUCTURES AND ROADWAY CONSTRUCTION PRACTICES. BRIEFLY, THIS REPORT (1) REVIEWS THE PROPERTIES OF CHARACTERISTICS OF THE MANCOS SHALE, (2) REVIEWS THE VARIOUS DESIGNS HWICH HAVE BEEN USED IN AN ATTEMPT TO PREVENT SWELLING, (3) INDICATES THE RELATIVE EFFECTS OF THESE DESIGN METHODS, AND (4) ATTEMPTS TO EXPLAIN WHY THESE DESIGNS WERE NOT SUCCESSFUL.
