General description of cutback asphalt RC 70
Bitumen RC70 is dissolved of bitumen 60/70 in ultra-light solvents. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.
The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result.
Uses of cut back asphalt RC 70
In the field of road construction, cutback agents play a vital role in optimizing the performance of asphalt. Explore our range of cutback bitumen products today to enhance your construction projects. This transformative process significantly contributes to improving the overall surface quality, ensuring optimal performance and longevity of road infrastructure. The process is essential for enhancing surface quality, and ensuring optimal road performance in the pavement aggregate base course or substrate. The concentration of kerosene as a bitumen cutback agent varies based on local conditions and requirements.
The cutback bitumen stands out as an ideal choice for prime coat and cold applications. Its ease of use is underscored by the absence of the necessity for thinning and heating.
