“…In accordance with the draft specifications for SMA (SMA-DS) [11], the design procedure of the bituminous mixture was based on the air void content (EN 12697-8) of compacted samples with 50 blows/side with a Marshall hammer (EN 12697-30) [4,14,15] and posterior checking of the water sensitivity (EN 12697-12), binder drainage (EN 12697-18) and resistance to permanent deformation (EN 12697-22).…”

Due to the high oil prices the price of asphalt binder has increased tremendously. This scenario has warranted demand for higher viscosity cheaper asphalt for pavement construction. A study was conducted to take advantage of the Empty Fruit Bunch (EFB) of Date and Oil Palm trees (which are considered as waste) to produce cellulose fiber to be used as additives in the asphalt binder. If these EFB's could be beneficially utilized in any application, it would reduce the load on the nation's landfills and at the same time reducing the cost of road construction. A total of 11 blends were prepared that consisted of 5 blends with date palm fiber, 5 blends with oil palm fiber and one control sample that contained no fibers. The samples were evaluated using Dynamic Shear Rheometer (DSR) equipment in accordance with the superpave Strategic Highway Research Program (SHRP) requirements. The neat asphalt binders (Unaged), Rolling Thin Film Oven (RTFO) aged and Pressure Ageing Vessel (PAV) samples were then measured for phase angle, shear strain and complex shear modulus and then evaluated in accordance with SHRP requirements. The results indicated that the fibers enhanced the rheological performance of Bio Mastic Asphalt (BMA) blends. The control sample which was categorized as PG58 was enhanced to PG76 with 0.375% date palm fiber. The oil palm has also improved the blend up to PG70 with 0.3% oil palm fiber.

“…Moreover, the natural fibers prevented the bitumen or bitumen/filler from draining down. Sharma and Goyal (2006) studied the use of crumb rubber modified bitumen. They conducted laboratory experiments on stone mastic asphalt (SMA) mixtures produced with crumb rubber modified bitumen and natural fibers.…”

Stone Mastic Asphalt (SMA) mixtures are susceptible to drain down since they contain more bitumen comparing to Hot Mix Asphalt (HMA) mixtures. To prevent this problem, stabilizers are used in SMA mixtures. Stabilizers are costly materials and needed to be manufactured with several processes. In this study, pumice and diatomite materials were evaluated to see whether they could be used in SMA mixtures as stabilizers. The optimum bitumen contents of the mixtures having different amounts of pumice (1, 1.5 and 2%) and diatomite (0.25, 0.50, 0.75 and 1.00%) were determined in accordance with Marshall design method. Then, the drain down characteristics of SMA mixtures at optimum bitumen content were found. Finally, the resistance of the mixtures to moisture-induced damage is analyzed by conducting the Tensile Strength Ratio (TSR) test. The results indicate that there is a high potential of using certain amounts of pumice and diatomite in SMA mixtures as stabilizers.
