摘要：The growing concern over the reduction of emissions and energy savings has led to the development of new paving technologies that are environmentally friendly. As a result, a warm mix asphalt technologies have been introduced to reduce the mixing and compaction temperature for asphalt mixture. The influence of additive with variation loading on the performance of Natural Rubber Modified Bitumen was acquired. In this work, Brookfield rotational viscometer test and Dynamic Shear Rheometer (DSR) mechanical analysis method and typical bitumen tests were employed. Results indicated that viscosity and the penetration of the Natural Rubber Modified Bitumen decreased, while the softening point increased with addition of additive. This in return would possible to reduce mixing and compaction temperature of the Natural Rubber Modified Mixture. Findings of the study also showed that the additive resulted in increase in complex shear modulus value and the rutting parameter modulus.
