Measuring the Elastic Deformation of Asphalt-Concrete Beams with the use of a Capacitive Sensor
Abstract: A method for measuring deflections of an asphalt-concrete sample under the action of cyclic loads using a capacitive sensor of the original design is proposed. The results of measurements of elastic deformations of various types of asphalt concrete are given. It is shown that the elastic deflection with values from 10 to 60 microns is characteristic for all types of asphalt concrete and in the time interval of testing the samples 60–70 % of the total test time. It has been established that asphaltic concrete with the complex-model structure of ethylene glycidyl acrylate Elvaloy-AM possesses 3 times more resistance to plastic deformations unlike traditional asphalt concrete.
Keywords: asphaltic concrete, fatigue life, deflection, capacitive converter, flat capacitor.
