Production and Application of Modified Emulsified Asphalt

Production and Application of Modified Emulsified Asphalt

Asphalt, including emulsified asphalt, is used as a pavement material in a viscoelastic state within a certain temperature range. As the temperature gradually decreases, the elasticity will gradually decrease, and the brittleness will increase, and the hardness will increase. When the temperature drops to a certain value, the asphalt will be inelastic and will change to a brittle state called a glassy state. When the temperature increases to a certain value, the asphalt softens to a flowing state and completely loses its elasticity, which is called a viscous flow state. Asphalt can only exert its normal performance when it is in the temperature range corresponding to the viscoelastic state. In the temperature range corresponding to the viscous flow state and the glass state, the performance of the asphalt is rapidly reduced. If the pavement is paved, the pavement will be highly susceptible to disease and cannot meet the requirements of the vehicle. In view of the fact that the viscoelasticity interval of the asphalt itself is very small, it is difficult to meet the performance requirements of modern highways if the asphalt is directly paved on the road surface. In order to expand the viscoelasticity range of the asphalt itself and expand the effective use range, the most common method used by modern people is to modify the asphalt. The modified asphalt not only can resist high temperature and low temperature, but also has good performance against rutting. Therefore, modern road construction is basically all used modified asphalt. Although modified asphalt has many advantages, the modified asphalt must reach the viscosity requirement of mixing and rolling at a relatively high temperature (generally about 160~170 °C). There are certain limitations on the construction conditions and construction period, and the consumption of energy and resources is large, and the emulsified asphalt can supplement its deficiency well.

Emulsified asphalt has many advantages. It can not only be used for cold construction, improve mixing uniformity, but also can save nearly 20% of asphalt raw materials. It can also expand construction period and reduce pollution, so it has been widely used. However, the emulsified asphalt is essentially another form of existing asphalt, so the weakness of the asphalt's own viscoelastic range is not changed. Modern engineering puts high demands on the high temperature performance, low temperature performance, anti-aging performance, rutting resistance and durability of emulsified asphalt. This also promotes the production and development of modified emulsified asphalt.
