摘　　要：分析了半刚性材料的压实原理、压路机的性能和碾压工艺,发现传统的碾压机械组合有使基层上下材料不均匀和压碎集料的缺点,由此提出新的压实机械组合,通过现场试验表明新的压实机械组合可以克服传统碾压机械组合的缺陷,并具有比传统碾压组合更易达到规定压实度的优点。Compacting mechanism to semi-rigid base materials and properties of compacting plant and technics of roller compaction are analyzed, it is found that the base materials are not uniform up and down, and aggregates are crushed in the traditional combination of compacting plant. Then new combination of compacting plant is put forward, through testing it not only overcomes the disadvantages of traditional combination of compacting plant, but also have the advantage of reaching required degree of compaction easily.

关 键 词：压实机理 碾压机械组合 压实度
