Study on Physicochemical Properties and its Effective Use of Asphalt Pavement Cutting Waste Water

Kimitoshi Hayano, Arisa Matsumoto

Abstract

While cutting asphalt pavement surfaces, cooling water is continuously given to the cutting machine blades to prevent the heat increase and to control the scatter of cutting dusts. As the results, asphalt pavement cutting waste water is generated. The amount of waste water generated at one construction site is by no means a lot, however, the water quality is not environmentally friendly. In view of above, the physical and chemical properties of cutting waste water were first investigated. Then the possibility of effective use of the cutting waste water was investigated using flocculants and granulation technique. The results show that the waste water quality can be improved by the effects of flocculants. Mud sediments after flocculated in the waste water can be granulated and the granules may be used as recycled sands or recycle crusher-runs aggregates.
