Abstract

Dry SBS-modified asphalt pavement technology is to produce SBS-modified asphalt mixtures by adding specific SBS modifiers, which aims to solve the performance degradation of SBS-modified asphalt in transportation and storage. By relying on the coastal highway repair projects, this paper compared the effects of different dry SBS mixing contents on the test results by the indoor dry SBS and matrix asphalt compatibility test and asphalt mixture performance evaluation test. Meanwhile, based on the test results, the recommended dry SBS mixing content for the coastal highway upper layer milling and resurfacing maintenance project was proposed and applied on a large scale in combination with the project. The application effect shows that under the recommended optimal dry SBS mixing content, the asphalt pavement features excellent performance, reasonable cost, and prominent popularization significance.
