Temparuture Control Of Bitumin Mixing

Comparative study of modified bitumen binder properties collected from mixing

Quality control and assurance are essential in pavement construction. In general, the properties of bitumen change as it ages in bulk storage, transport, and storage on site. The minimization of bituminous hardening during storing, transportation and mixing depends on careful control of binder temperature. Hence therefore, bitumen should always be stored and handled at the lowest temperature ...

How is Asphalt Made? | Asphalt Production Process – Mixer Direct

Jun 25, 2019 · Asphalt is graded based on the ranges of viscosity, or consistency, at a given temperature. Careless mixing- and temperature-control procedures can cause more damage to paving asphalt during the hardening phase than many years of vehicle traffic. A standardized penetration test is generally specified when determining paving asphalt consistency.
