ADOPTION OF MORE REALISTIC VALUES FOR THE ELASTICITY MODULI AS CHARACTERISTICS FOR THE ELASTIC DEFORMATION BEHAVIOUR OF FLEXIBLE PAVEMENTS IN ELASTICITY THEORY STRESS CALCULATIONS

ZUR ANNAHME WIRKLICHKEITSNAHERER E-MODULI A/S KENNWERTE FUR DAS ELASTISCHE VERFORMUNGSVERHALTEN FLEXIBLER STRASSENBEFESTIGUNGEN BEI ELASTIZITATSTHEORETISCHEN BEANSPURCHUNGSRECHNUNGEN

In the present work a systematic analysis of the behaviour of flexible pavements is used as the basis for an attempt at obtaining more realistic values for the moduli of elasticity (E-moduli) as the most important input data for elasticity theory stress calculations. First of all the E sub v2 values from the plate-loading test measured for the individual pavement layers are recalculated to give, in each case, an E- modulus which is constant throughout the layer. Since the basic data have been obtained from road pavements representing all current methods of construction and in all stages of operation from initial construction to the appearance of the first signs of damage, E-moduli could be given, differentiated as to time and location and as a function of the properties of the materials, constructional data, and the environmental and loading conditions. Here, therefore, for the first time we have a complete collection of 3-moduli for comparatife stress calculations.
