Abstract

Highways play an important role in developing the country. Highways affect directly on the economy, society, culture and security, so the scientists are looking for developing the performance of highways and low maintenance cost. The main objective of this study is to modify the bituminous mixed by utilization of waste industrial materials. , There are many wastes industrial materials can be used in bitumen. A study has been carried out in this search to illustrate the use of fly ash, (byproduct of combustion Pulverized coal in power plants , it produced during combustion of coal in bituminous paving mixes), Silica Fume,( by- product of producing silicon metal or ferro silicon alloys in smelters using arc furnaces) . For comparison, control mixes with modified bituminous mixes has been considered. Marshall Test has been conducted for the purpose of mix design as well as appreciation of paving mixes. It is observed that the mixes with fly ash and silica fume as modifiers modify the properties compared to control mixes. In this paper Silica Fume and Fly Ash are used as a modifier. Marshall stability test was conducted according to( ASTM D 6927-06 ). The percentages of modified mixtures used are 2, 4, 6, 8 and 10 % by bitumen weight. The results showed that the Marshall stability modified with SF and F.A were increased by 18.4% and 22.3 % respectively. So, we can concluded that adding SF and FA to asphalt binder success in improving the properties of bituminous mixes for flexible pavement. Hence, it has been recommended to utilize Silica Fume and Fly Ash wherever available, not only reducing the cost of construction, but also solve the bituminous mixes properties.
