摘要

The Wisconsin Department of Transportation (WisDOT) has implemented the super pave recommendations in the 2000 Supplemental Specifications. This research was directed towards better understanding of the influence of angularity of fine aggregates, asphalt content, and performance grade of asphalts on hot mix asphalt (HMA) performance. Aggregates from four sources across the state of Wisconsin were used in this study. Each source provided two blends that vary in gradation: (1) a fine blend and (2) an S-shaped blend. Testing was accomplished using the super pave gyratory compactor (SGC) and a device that fits inside of the SGC known as the gyratory load plate assembly (GLPA). Mixture densification and performance indices were calculated based on the data obtained form both the SGC and GLPA.

7. Stone Matrix Asphalt (SMA) is a gap-graded mix that is gaining popularity worldwide. Generally, gap graded mixes are thought to be weak in fatigue resistance. In this study, cellulose fibers were pre-blended in PG64-22 binder with fiber proportions of 0.2%, 0.4%, 0.6%, 0.8% and 1.0% by weight of aggregates. The fiber-modified binder showed improved rheological properties and showed that the PG64-22 binder can be modified and raised to PG70-22 grade. The cellulose oil palm fiber (COPF) was found to improve the diameteral fatigue performance of SMA design mix. The fatigue life increased to a maximum at a fiber content of about 0.6%, whilst the tensile stress and stiffness also showed a similar trend in performance. The initial strains of the mix were lowest at a fiber content of 0.6%. [O] . Ratnasamy Muniandy, Bujang B.K. Huat 2006
