26 2024-07: What is the blend and why does SBS improve the elastic modulus of bitumen so much?

A blend is a material consisting of two or more different substances mixed together. In the reference article, a blend refers to a mixture formed by adding SBS (Styrene-butadiene rubber-styrene-butadiene copolymer) to a base bitumen.There are several reasons why SBS can improve bitumenelastic

16 2024-07: What is the relationship between the change of ductility and viscosity during bitumen modification and the shear and development time? Why does elongation decrease during development?

In the process of bitumenmodification, there is a certain relationship between the change of ductility and viscosity and the shear time and the development time. During the shearing period from 30 minutes to 2 hours, the ductility increases significantly and the viscosity also increases substa

28 2024-06: How to choose the right process to produce modified bitumen that meets the requirements of the code?

The selection of a suitable process to producemodified bitumenthat meets the requirements of the code requires consideration of the following factors:1. Selection of raw materials: The selection of the right matrix bitumenis the key, according to the requirements of the code to sel

26 2024-06: When selecting SBS modified bitumen production equipment and parameters, what factors should be considered to ensure production quality and efficiency?

1. The design production capacity of the equipment: When selecting the equipment, the design production capacity of the equipment should be determined according to the production demand. The design and production capacity of the leading equipment is the basis for determining the matching of other eq

14 2024-06: What is the impact of the design capacity of the equipment on the production of SBS modified bitumen?

First of all, the design production capacity of the equipment determines the production efficiency and capacity of the production line. If the design production capacity of the equipment is insufficient to meet the production demand, it will lead to low production efficiency and insufficient capacit
