Abstract:
VOLUME CHANGES OF SUBGRADE SOIL ARE RESPONSIBLE FOR SETTING UP CONDITIONS UNDER WHICH RIGID-TYPE PAVEMENTS ARE SUBJECTED TO HIGH STRESSES NOT ALWAYS CONSIDERED IN THE DESIGN OF THE SLAB. WATER PERCOLATING THROUGH JOINTS AND CRACKS IN CONCRETE PAVEMENTS CAUSES CERTAIN COHESIVE SOILS TO SWELL AND RAISE THE SLABS AT THESE POINTS. THE SWELLING OF SOIL DEPENDS ON ITS CAPILLARY PROPERTIES.
