Since 1968, our district started to construct asphalt pavement. Up to now, there are 1350 kilometers of asphalt pavement in the whole region. In recent years, the black pavement has not only increased rapidly in quantity, but also gradually improved in terms of project quality and construction standards. A few years ago, Mostly built road mix (cold mix) asphalt (residue) surface at the table, while a small part of the asphalt into the road. In 1974, after the trial manufacture of semi-fixed asphalt concrete mixer, we began to construct a part of asphalt concrete pavement by means of mechanical hot-mix hot-laying method. Since the pilot test in the winter of 1974, four years ago, both Pingdu County and Yidu County took the road from Weifang to Shidao and Wangcun to Weifang
