To determine the addition ratio of Bitumen Emulsifier, we need to consider the type of asphalt, construction requirements, and the characteristics of the emulsifier itself.
Different types of asphalt, such as petroleum asphalt and coal asphalt, have different compositions and properties, and require different amounts of emulsifier. Generally speaking, hard and viscous asphalt requires more emulsifier to disperse it into uniform small particles. Construction requirements are also critical. If the road surface to be paved is thick and the strength requirements are high, the emulsifier ratio can be appropriately increased to ensure better adhesion between asphalt and other materials; if it is only a small area of road surface repair, the amount can be less.
Each Bitumen Emulsifier has different performance. Some have strong emulsification ability, so the addition ratio can be lower; some emulsifiers are relatively weak, so the amount must be increased. Usually before formal construction, experiments must be conducted first to mix asphalt with emulsifiers in different proportions, observe the emulsification effect and stability, and select the most appropriate addition ratio to ensure construction quality.
