adhesive SBS Materials along with environmental and technological progress, and now there have been powdered SBR. Powdered SBR due to the current size restrictions, for the production of SBR modified asphalt has obtained good results, but it can meet the SBR-modified asphalt emulsion stability requirements, needs to be further verified in practice. Modification of additives and functional differences between admixture; magnesium cement admixture a lot, but not all of the additives are modifiers, some functional additive, the two should not be confused. Functional additives and modification of admixtures are two different concepts. Modified admixture is mainly to overcome the ills of magnesium cement to improve its performance, it added. Functional is not additive to improve the performance of magnesium cement, but rather to give magnesium cement with a variety of special features, it can not overcome its ills. For example, the functional additive is not to improve the performance of magnesium cement, but rather to give a variety of special properties of magnesium cement, it can not overcome its ills. For example, the functional additives beads pigment, which can make concrete look shiny magnesium to increase its aesthetics, but it will not change the product’s performance. Another example of functional additive powder, which can make products have a strong magnetism, but it does not overcome the product’s ills. Modification of functional additives and admixtures for the purpose of the add is different, pouch efficacy of pouch two are also different. SBS is the production of modified emulsified asphalt of the most promising as a modifier. The SBS powder by mechanical means can produce high quality, low cost of SBS modified bitumen emulsion; Another way is through charge plus dispersant, reduced viscosity, first granular, SBS modified by re-liquefaction and liquefaction However,yoga mat bag, the method of production costs are high, emulsion pavement performance is also subject to a certain extent.
