bitumen was prepared by using a high shear mixing homogenizer (IKEA model). Firstly, bitumen was heated up to 180±5 °C in a small container until it flowed fully, then upon reaching 180 °C, VB was added to bitumen in 5 min. A given part of SBS (4%, 5% and 6% of the weight of the base asphalt) was gradually added (5 g/min)
Home / Concrete Forms / Fuel and Liquid Storage Tank Systems We worked closely with the regulatory agencies while designing these vessels to protect the environment and ground water from accidental spills and leaks from above ground petroleum storage tanks.
We are counted among one of the renowned manufacturers, suppliers and exporters of fine finish Ready Mix Concrete Batching Plant. Only high quality metals are used in designing and development of these plants. These plants are equipped with highly functional control panels so as to control the operations of the plants.
The rotational viscometer was also used to establish equiviscous temperature ranges for selecting HMA mixing and compaction temperatures. Hence, this study can lead to further studies on the use of crumb-rubber- and SBS-modified asphalt in hot-mix asphalt. 2.4. Conventional tests
Crumb rubber modified bitumen (CRMB) has been widely used in pavement construction and provides an effective way to recycle waste tires and helps alleviate the “black pollution” problem. There are no current specifications regarding the appropriate mixing and compaction temperatures of the CRMB mixture. There is a direct relationship between the mixing …
Batch mixers enable you to mix cement slurries and other fluids and feature two centrifugal pumps for delivering fluid to high-pressure pumps, recirculating cement slurries for mixing in blending tanks, and transferring fluids from remote tanks. The batch mixers can handle large volumes of cement slurry and significantly reduce fluctuations in ...
Two samples were produced by adding 4% SBS polymer to the same base binder but using different blending techniques. One sample was produced with a linear SBS, not the optimum forthe base asphalt, and it did not undergo high shear mixing. Theother binder was produced with a radial SBS polymer,optimum for the base binder and mixed in with high shear.

When SBS comes in contact with the bitumen, at a high temperature, the latter makes the polymer "swell" and is distributed in its inside. The interactions between bitumen and SBS take place initially, preferably involving the flexible phase of the polymer, as this represents its matrix and also due to its greater free volume.

performance, especially when high temperatures/low frequencies are considered. • The high temperature behaviour of SBS modified binders differs from normal penetration grade bitumen: the SBS exhibits shear thinning behaviour while the 60/70 exhibits normal Newtonian behaviour. Thus, the shear rate during mixing and compaction is very important
