Infrared Spectrum Analysis of Aged Asphalt Regenerated by Recycled Engine Oil Bottom
In order to analyze the feasibility of recycled engine oil bottom (REOB) as a regenerant for old asphalt and to determine its improvement effect on the performance of recycled asphalt, this paper analyzes the functional groups of two kinds of old asphalt and matrix asphalt through infrared spectrum...

| description | In order to analyze the feasibility of recycled engine oil bottom (REOB) as a regenerant for old asphalt and to determine its improvement effect on the performance of recycled asphalt, this paper analyzes the functional groups of two kinds of old asphalt and matrix asphalt through infrared spectrum test, such as carbonyl group, butadiene double bond, styrene double bond, methyl group, methylene group, and aromatic ring in the molecules of REOB. Find out the compatibility characteristics between them from the microscopic point of view. The recycled asphalt with 4%, 6%, and 8% content was prepared, and the physical property test was conducted to analyze the regeneration effect of different contents of REOB, and the optimum amount of REOB for 10-year-old asphalt was determined to be 6%. The study found that REOB contains aromatic hydrocarbons and colloids, which can supplement the reduction of aromatic hydrocarbons and colloids caused by asphalt aging. Therefore, REOB helps to adjust the composition of aging asphalt, improve its performance, and achieve good regeneration. |
