摘要
本文论证了厚半刚性材料层具有大幅度提高路面承载能力的优点,半刚性路面的承载能力完全可以通过半刚性材料层达到,沥青面层主要起保护基层,减轻干缩和温缩裂缝以及保证使用功能的作用;论证了半刚性材料层达到一定厚度后,继续增加其厚度对路面的承载能力的进一步提高无明显效果;推荐了可供实用的路面结构。
The advantage of increasing pavement bearing capacity to a consi- derable extent through thick layer of semi-rigid materail is demonstrated in this paper.The bearing capacity of the semi-rigid pavement can be fully dev- eloped by choosing appopriate semi-rigid materail layer,and the asphalt surf- acing will chiefly provide a protection for the roadbase,reduce the dry shrinkage and temperature contraction crackings,and make itself to be a functiona surfa- cing It is also demonstrated in the paper that if the thickness of the semi-rigid layer is more than a certain value,the pavement bearing capacity will not bel increased significantly.Finally,a series of practicable pavement structure are recommended
