用旋转压实剪切实验机 (GTM)设计方法设计的沥青混合料和粗密级配沥青混合料与一般沥青混合料相比 ,其压实要求高 ,压实难度大。压实是成功铺筑重载交通沥青混合料的关键因素。从适合的压实限制、压实空间(层厚与集料粒径大小关系 )、压实温度和压实作用等几个方面探讨了以防止车辙为主的重载交通沥青混合料的压实特性。
Asphalt mixture and coarse graded asphalt mixture designed by the GTM design method require compaction compaction and compaction difficult compared with common asphalt mixture. Compaction is the key factor in the success of paving heavy-duty traffic asphalt. From the aspects of suitable compaction limit, compaction space (the relationship between layer thickness and aggregate size), compaction temperature and compaction, the compaction of heavy traffic asphalt mixture to prevent rutting is discussed characteristic.
