Abstract

With the development of China's science and technology and large-scale construction of infrastructure, put forward higher requirements to the highway pavement performance, modified asphalt is necessary. Aging is a problem of modified asphalt in use process cannot be ignored, which directly affects the life of the road, is the main factor affecting the durability of asphalt pavement. This paper use PPA additive preparation of PPA modified asphalt, studies the effects of asphalt in different PPA contents modification. Using the modified asphalt rotating thin film oven, simulation of asphalt mixing and paving in the aging effects of high temperature and oxidation process of asphalt, by measuring the three performance of asphalt, studies the hot oxygen aging effects on modified asphalt performance. Analysis the improvement of different modifiers and modifiers added amount of asphalt aging properties.
