Abstract: This work improved the low-temperature rheological properties of asphalt modified with styrene butadiene styrene (SBS) using an acid modifier, namely polyphosphoric acid (PPA), and investigated the microstructural changes ...

Abstract: Skidding is a typical behavior of high-speed angular contact ball bearings. Studies show that the effect of preload on bearing skidding and thermal characteristic is essential but insufficient. This paper proposed a ...

Abstract: The novel cement grout asphalt composite (CGAC) in this study is a new semiflexible composite consisting of open-graded hot mix asphalt (HMA) filled by injecting cement grout materials. The mechanical performance and ...
