REPRODUCTION OF HIGH VISCOSITY MODIFIED ASPHALT & RECLAMATION OF POROUS ASPHALT MIXTURES

The test pavements using recycled porous asphalt are performed in each research institute, but drainage asphalt pavements are manufactured only with new material now, because the technology of recycling is not established. However, drainage asphalt pavements also need to consider to use of recycling aggregate from now on. Then, we examined the reproduction of porous asphalt mixtures with two kinds of aggregate, the recycling aggregate of drainage pavements, and conventional reproducted aggregate. Consequently, we showed clearly that each of two methods can put in practical use.
