STUDY ON HIGH GRADE HIGHWAY ASPHALT PAVEMENT CONSTRUCTION TECHNIQUES IN XINJIANG

The study achievements of two research projects i.e. "Constructing high grade highways ysing Xinjiang thick oil asphalt" and "Typical semi-rigid basecourse asphalt pavement structures of Xinjiang high grade highways" are described in following respects: (1) the classification for soil base grades; (2) the classification for accumulated equivalent life number of standard axles; (3) parameters of pavement materials; (4) the climate area division and use performance of the bituminous binders for Xinjiang (in China) high grade highway pavements; (5) the climate area division and typical structures for semi-rigid basecourse asphalt pavement of Xinjiang high grade highways; (6) effect observation on experimentAL roads and other related highway sections.
