EVALUATING THE STABILITY OR ROAD STRUCTURES BY MEANS OF STATIC-ELASTIC THEORETICAL CALCULATIONS (IN GERMAN)

ROAD STRUCTURES, THE PROPERTIES OF WHICH DEPEND BOTH ON DYNAMIC TRAFFIC LOADING AND CLIMATIC CONDITIONS, CAN BE CHARACTERIZED ON THE BASIS OF THEIR MOMENTARY BEHAVIOR UNDER STATIC LOADING. STANDARDS WERE DERIVED FROM THE BEHAVIOR OF PROVEN STRUCTURES, WHICH, TOGETHER WITH STATIC-ELASTIC THEORETICAL CALCULATIONS, RENDER POSSIBLE AN ADVANCE COMPARATIVE EVALUATION OF THE STABILITY AND ECONOMICS OF ROAD STRUCTURES. AN ELECTRONIC COMPUTER PROGRAM WAS EVOLVED TO DETERMINE THE STRESSES AND DEFORMATIONS OCCURRING IN MULTI-LAYER ELASTIC STRUCTURES UNDER VERTICAL STATIC LOADING. USING THIS PROGRAM A CURRENT STANDARD CONSTRUCTION METHOD WAS EXAMINED FOR CONSTRUCTIONAL AND ECONOMIC JUSTIFICATION. IT WAS SHOWN TO BE SUFFICIENTLY STABLE. HOWEVER, VARIATIONS ON THE STANDARD METHOD, WHILE BEING EQUALLY STABLE, WERE SOMETIMES MORE ECONOMIC. /FG/RRL/
