Abstract:
SUBGRADES NEED TO BE: (1) UNIFORM - FOR GRADE, CROSS SECTION, AND ALIGNMENT; (2) COMPACTED - TO CONTROL STABILITY AND COMPACTION; AND (3) DRY - FOR CONTROL OF WATER. THE QUALITY OF THE FINISHED SURFACE IS DEPENDENT UPON THE SUBGRADE, THUS, ANY IRREGULARITIES IN THE SUBGRADE APPEAR IN THE SURFACE. BY KNOWING THE FOUNDATION STRUCTURE OR THE NATURAL SUBSOIL MATERIALS USED IN CONSTRUCTION, CORRECTIVE MEASURES CAN BE TAKEN TO INSURE THE PROPER SPECIFICATIONS FOR SUBGRADES.
