沥青路面铣刨料表面沥青分层老化规律研究
Research on the Stratified Aging of Asphalt Pavemill Materials
摘要
Abstract
In order to study the stratified aging rule of asphalt pavement overlaid on the surface of asphalt pavemill materials, this study separated and extracted the bitumen in the milling material,and then conducted the analysis of infrared spectroscopy and gel permeation chroma-tography. The results showed that the oxygen aging on the surface of the milling materials gradually decreases from outside to inside,the aromatic content gradually increases,and the macromolecule content gradually decreases. In addition,the test finds out that the C=C double bond wave number of each layer changes and it is thus inferred that the change of C=O affects the conjugation between C=C and C=O.关键词
