Title: BEARING CAPACITY OF FLEXIBLE PAVEMENTS SUBJECT TO FROST ACTION
Accession Number: 00206192
Record Type: Component
Abstract: THE BEARING CAPACITY OF FLEXIBLE PAVEMENTS IS REDUCED CONSIDERABLY DURING THE SPRING BREAKUP PERIOD PARTLY BY REDUCTION IN RELATIVE DENSITY OF THE SUBGRADE MATERIAL AS A RESULT OF FROST ACTION, PARTLY BY THE SATURATION OF THE SOIL CAUSED BY THAWING AND PARTLY BY EXCESS PORE PRESSURE RESULTING FROM THE INCOMPLETE RECONSOLIDATION OF THE SUBGRADE. A METHOD HAS BEEN DEVELOPED BY WHICH THE ULTIMATE BEARING CAPACITY OF FLEXIBLE PAVEMENTS CAN BE EVALUATED. THIS METHOD IS BASED ON THE ASSUMPTION THAT THE SUBGRADE SOILS ARE FULLY SATURATED AND THAT THE WHEEL LOADS CAUSING FAILURE ARE APPLIED SO RAPIDLY THAT NO CHANGE IN WATER CONTENT TAKES PLACE DURING LOADING. THE CALCULATED ULTIMATE BEARING CAPACITY HAS BEEN COMPARED TO THAT DETERMINED BY A METHOD PROPOSED BY LINELL. GOOD AGREEMENT WAS FOUND BETWEEN THE TWO METHODS. /AUTHOR/
