乳化沥青乳液微粒粒径变化特征研究

乳化沥青微粒粒径大小和分布情况作为乳化沥青质量控制的重要参数,对乳化沥青的储存稳定性和使用性能有着重要的影响.通过分层微粒粒径试验,研究乳化沥青在储存过程中的微粒粒径变化特征,发现乳液微粒的平均年粒径随时间增加而递增,随深度增加而增大,且随着乳化剂含量的增加而减小,研究结果为乳化沥青的生产、储存和施工提供理论参考.

Study on Particle Size Variation Characteristics of Emulsified Asphalt Emulsions

As the important parameters of controlling the quality of emulsified asphalt, the particle size and distribution of emulsified asphalt have the important effect on the storage stability and using performance of emulsified asphalt. The particle size variation characteristics of emulsified asphalt in the storage process are studied through the stratified particle size test. It is found that the average annual particle size of emulsified particle size increases with the time increment and with the depth increment, and decrease with the increment of emulgator content. The study result provides the theoretical reference for the production, storage and construction of emulsified asphalt.
