A System for Road Pavement Composite Material Deformation ()
ABSTRACT
For a comprehensive
experimental evaluation of the material quality, forecast of the properties and
parameter change of the bituminous material was made at the time under the
impact of external factors, they are subjected to the necessary tests. In the
article the automated set “Tomsk-Asphalt-Test” for determining
the elastic modulus of the specimens made of bituminous materials was used in
road pavements, maximally close to natural conditions of operation of highways
of the Siberian region inRussiaare described. The automated set contains: electromechanical, climate,
electronic, PC and software subsystem. The operation principle is a short-time
deformation of the asphalt specimens; measurement of physical values: the
stress, strain, variation of the size line and temperature of the asphalt
pavement material test specimen, converting the measured values into electrical
signals, their program processing and visualization. The control of testing and
viewing results of measurements is carried out in accordance with the menu
software subsystem. The results of calculations: the maximum values of vertical
load the difference between the maximum horizontal deformation value and the
value measured last after specimen of asphalt material loading for each test
cycle, the sum of the differences of the horizontal deformation values of the
two sensors and modulus of elasticity.
