摘要

The state of South Carolina contains two-slag-producing facilities: a chromeplant in Charleston and a steel plant in Georgetown. There has been some interest shown by the South Carolina Department of Transportation, in using slag in construction of state-funded roads. Prior to the acceptance of a new aggregate for state-funded projects, many tests must be conducted to ensure the products's acceptability. This project was conducted in order to determine if chrome and/or steel slags would be acceptable aggregates in Hot Mix Asphalt. A literature review was conducted to reveal and past research on this subject, and their results. A plan of study was developed to focus on tests that would relate useful chararcteristics concerning the aggregate. Finally, the tests were performed and evaluated. The report concluded that both chrome and steel slag aggregates can provide satisfactory HMA mixtures if the expansive nature of steel slag aggregates is adequately treated and if the stripping potential of the mixture is counteracted.

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
