Abstract

In order to study the influence of humidity on the performance of asphalt mixture, vacuum drying oven and constant temperature and humidity box were used to carry out humidity curing on AC-20C asphalt mixture specimen. A uniaxial penetration test, triaxial test, low temperature bending test, and uniaxial compression dynamic modulus test were carried out to obtain the high and low temperature performance of the selected asphalt mixture and the dynamic modulus and phase angle under different temperatures and frequencies. The main curve of the dynamic modulus was drawn. Through the analysis of the test results, the following conclusions are obtained: Humidity has a great influence on the high temperature performance of asphalt mixture. With the increase in humidity, the cohesiveness of the asphalt mixture decreases, and its high temperature stability mainly depends on the interlocking action of aggregate. The conversion of gaseous water to a solid state in the asphalt mixture due to the decrease in temperature will destroy the asphalt–aggregate interface characteristics of the asphalt mixture, resulting in a rapid decline in the low temperature performance of the asphalt mixture. Humidity also has a great influence on the viscoelastic properties of asphalt mixture at room temperature. Specifically, with the increase in humidity, the phase angle is more sensitive to temperature change, and the main curve of dynamic modulus of asphalt mixture gradually decreases in the low frequency range, which damages the ability of the asphalt mixture to resist permanent deformation in this region.
