路面基层二灰碎石若干技术问题探讨

Some Technical Problems of Pavement Base with Lime-Fly Ash Macadam

路面基层是沥青砼路面的主要持力层,基层施工质量的好坏,直接影响路面的使用寿命。结合工程实际,对影响基层质量的因素如原材料、配合比、施工机具、检测等进行了探讨,并提出了相应的对策。

The pavement base is the major bearing stratum of asphalt concrete pavement. Construction quali ty of base directly affects the service life of pavement. Combining with engineering practice, the paper summa- rizes and discusses raw materials, mix proportion, construction machines, test and other factors affecting base quality and proposes relevant countermeasures.
