摘要

This paper introduces the newly researched binder(CGLS)used in the construction of the road base and the road performances of CGLS stabilize loess(Xi'an)and grading aggregate. The main ingredient of CGLS is the powder of ground granulated blast furnace slag(GGBFS), which has the proportion of 75%. Portland cement, lime, and gypsum activate the powder of GGBFS. The paper analyses the hydration mechanism using X-ray diffraction(XRD).The test results indicate that having some advantageous properties including long setting time, macro expandability and with over 32.5MPa 28d age's strength, the binder(CGLS)is more suitable for the base course construction than the ordinary Portland cement(OPC).

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
