Applying master curve at the grids strengthened asphalt structures

Abstract

The master curve is an appropriate tool to describe the behavior of the different asphalt mixtures. We can analyze the attitude of the asphalt at very special time and frequency range using master curve method and in this extreme condition we could not solve without it. Different shift coefficients calculation's methods were showed in this study. According to a Dutch (Sigmoid) method, the slope of the master curve determines the fatigue characteristic of the asphalt mixture. In this article we analyze and compare the master curves of the grid strengthened and non grid asphalt structures.

The effect of VIATOP plus FEP on the stiffness and low temperature behaviour of hot mix asphalts

“…The effect of stiffness on fatigue performance and thus service life of a layer has also been shown [11]. Stiffness should be interpreted together with the testing temperature and should be tested at different temperatures [12]. The stiffness tests were carried out at 20 °C according to European standard EN 12697-26 and at further three temperature levels (10 °C, 30 °C, 40 °C).…”
