Abstract
After years of use, there’s oil loss on the asphalt pavement. the bond strength of aggregate decreases. Loose threshing is serious. In order to improve the pavement performance, Extend the service life of pavement , Improve the safety of aircraft operation. we test the SMA-16 modified asphalt mixture on the runway of Da Lian Airport from many factors, including raw materials, admixtures, gradation design, optimum ratio of oil to stone, then we find the best ways to resolve it.
Highlights
After years of use, there's oil loss on the asphalt pavement, the bond strength of aggregate decreases
Equivalent brittle pointT1.2(°C) Flash point(COC)(°C) Elastic recovery(15°C). It appears that all the performance indicators meet the technical requirements, we can use this asphalt
Test items Bulk specific gravity Apparent specific gravity. It appears the bulk specific gravity and the apparent specific gravity all meet the technical requirements, we can use them in the project
Summary
There's oil loss on the asphalt pavement , the bond strength of aggregate decreases. In order to improve the pavement performance, extend the service life of pavement , improve the safety of aircraft operation, we test the SMA-16 modified asphalt mixture on the runway of Da Lian Airport from many factors , including raw materials, admixtures, gradation design, optimum ratio of oil to stone, we find the best ways to resolve it
