RESISTANCE OF FLEXIBLE PAVEMENTS TO FATIGUE /IN RUSSIAN/

THE FATIGUE PHENOMENON IS DESCRIBED AS MODIFICATIONS IN FLEXIBLE PAVEMENT LAYERS, CAUSED BY REPETITIVE LOADING, WHICH RESULT IN THE PROGRESSIVE DISINTEGRATION OF THE FRAMEWORK AND WEAKENING OF THE LAYERS. THE OPINION HELD BY THE KADI, USSR, CONCERNING THE FATIGUE OF UNTREATED LAYERS IS OUTLINED. ATTENTION IS DRAWN TO THE FACT THAT TO THE EFFECTS OF THE TRAFFIC MUST BE ADDED THE RESISTANCE OF THE AGGREGATES TO CRUSHING; DESTRUCTION BY FATIGUE IS, IN EFFECT, AN INCREASE IN THE FREE SURFACE OF AN ENERGY INDEX (RELATED TO THE UNIT OF FREE SURFACE AREA CREATED). NUMEROUS OTHER FACTORS REMAIN TO BE STUDIED: INFLUENCE OF LOAD PER WHEEL, WHEEL PRESSURE ON THE ROAD SURFACE, REPETITION OF LOADS, WEATHER CONDITIONS, AND STIFFNESS OF THE LAYER STUDIED. /TRRL/
