Asphalt recyling is now mandatory in South Korea under new legislation introduced as part of the government's drive to raise environmental awareness. This new law has resulted in a raft of recycling plants being used on highway projects.
Main contractor Hyundai is currently renting a Metso Minerals Nordberg mobile crusher for use on its contract for the widening of 150km of the Jungbu highway which runs between the capital Seoul and Daejon.
The four lane highway is being increased to eight and much of the existing road is also being rehabilitated. Once completed, the upgraded route should alleviate a number of notorious bottlenecks as well as cutting driving time between the two cities by half.
The Nordberg crusher was chosen because of its mobility and is currently working 40km south of Seoul near the city of Icheon. Stockpiles of broken-out asphalt are being processed for re-use as sub-base and for use in embankments as the highway has to negotiate a number of steep hills.
Working eight hours a day, six days a week, it is estimated that the crusher will handle a total of around 37,000m 3ofasphalt, producing processed material below 100mm.
Hyundai is renting the Nordberg crusher from Seoul-based New Tech Rental. According to New Tech Rental president UT Jeong, contractors working in Korea are making a definite move to renting this type of equipment. The company has three Nordberg mobile crushers in its fleet which are 'always out on site', he says.
