Application of cement and asphalt emulsion to in situ recycling base course method

The method of "In situ recycling with cement and asphalt emulsion to obtain a stabilized base course" is one of recycling techniques using the existing asphalt mixture and some granular base course material to build a new base course. It uses a specific pavement machine called "in situ crushing and mixing machine" to crush the existing pavement while evenly mixing and compacting cement and asphalt emulsions to make a base course. Generally, ordinary Portland cement and non-ionic emulsion providing superior miscibility with cement are used. As a result, a highly-durable stabilized base courses with the rigidity of cement treated materials and the flexibility of asphalt concrete is obtained. Furthermore, this method reduces pavement-waste materials by recycling the existing pavement; it can shorten the construction period because of in situ method; it is less expensive than the reconstruction method. It can state that it is a resource and energy-efficient method allowing cold manufacture and construction to contribute to the conservation of global environment.
