抄録

It was clarified in our previous papers that chemical materials which may impact the environment and ecosystem are included in the water cooling cutters for asphalt road improvement. A treatment system of the cutting water was developed, which can continuously collect and separates it into filtered water and the residues including toxic substances. In this paper, the developed system had been used in several works on asphalt road improvement. As a result, the system was improved to be operated more steadily. In addition, the residues were solidified by using coagulant to prevent toxic substances from scattering discharging into the environment.
