Maintenance of Machinery and Equipment for Expressway Maintenance
<P>Here discusses the application of emulsified asphalt pavement and developments illustrate the production of the emulsion, the emulsion formulations, emulsions and emulsions in various spreading in the application.</P>
<p>Emulsified asphalt is composed of two immiscible material - a mixture of bitumen and water. The emulsion particle size is a more important parameter since the particle size becomes single, dispersion, emulsion viscosity will be better, and bond breaking performance is more suitable. However, this also limits the bitumen content of the emulsion, which affect the speed of curing, in general, when the particle diameter was found by VSS has the best overall characteristics in a range of 1 ~ 5μm.</p>
<P>Composition and chemical properties of bitumen are complex. With high polarity (polarizing) and higher aromatic asphalt, generally easier to emulsify. Additives can be used to improve emulsification, in general, a high penetration bitumen emulsion easier than the low penetration of asphalt.</P>
