Azalt In-block: a new packaging of bitumen facilitating transport at ambient temperature

Hot bitumen transportation is a major obstacle to the development or progress of infrastructure in the world. Generally, the bitumen shipping by truck is limited to 200-300 km. Delivery time is very dependent on the quality of the road infrastructure. To reduce this constraint, different technologies are available across the world. This paper presents a new technology to transport bitumen at room temperature in the form of blocks of 25 kg. Experiments were performed with different bitumen at laboratory scale. This new packaging does not affect the viscosity at high temperature. In addition, there is no dramatic effect of this packaging on the low temperature properties after aging process. There is no detrimental effect of the additivation on the mixes characteristics (water resistance, rutting, modulus and fatigue test). Finally, creep measurements show that manufactured blocks can resist deformation at a high temperature.
