Abstract

Abstract:

The current DSR test and BBR test have limitations in evaluating the fracture performance of warm mix asphalt. In order to accurately predict the effect of warming agent on the fracture properties of asphalt materials， two different types of warming agents （Sasobit and ET-3100） were added to the matrix asphalt， then the rotating thin film oven（RTFO） and pressure aging vessel（PAV） tests were carried out to study the fracture properties of the warm mix asphalt. The extended bending beam rheometer（Ex-BBR） test and double edge notched tension（DENT） test were conducted to characterize the low strain rheological and high strain ductile fracture properties of the warm mix asphalt. In addition， Fourier transform infrared spectroscopy（FTIR） test was conducted to compare the molecular structure of asphalt before and after the addition of warming agent. The test results show that addition of 3% Sasobit and above can significantly reduce the low strain rheological properties and high strain ductile fracture properties of asphalt. ET-3100 can slightly reduce the ductile fracture resistance of asphalt， and this the effect has nothing to do with the amount of ET-300. The FTIR test results show that warming agent ET-3100 slows down the aging degree of asphalt， which is manifested by the reduction of hydroxyl C=O and sulfoxide S=O.

Key words: road engineering, warm mix asphalt, fracture property, low-temperature performance, extended bending beam rheometer test, double edge notched tension test
