Processing of four point bending test results for visco-elasticity and fatigue models

Abstract

The paper deals with the processing of the data of the four point bending tests carried out for determination of material properties. The tests are interpreted throughout the Bernoulli’s beam theory with neglecting dynamical influences at the start of the test. Presented interpretation is done mainly for problems dealing with determination of visco-elastic, thixotropy and fatigue properties of road bituminous materials.
