description The invention discloses a construction method for highway subgrade treatment. The construction method comprises the following steps: 1, performing survey setting-out; 2, performing substrate treatment; 3, performing a drainage groove; 4, performing pipe pile construction; 5, performing layered filling and compacting; 6, performing surface layer construction treatment, wherein the base treatment inthe second step comprises the following steps: firstly, cleaning the roadbed ground obtained after survey setting-out, so that organic impurities and floating soil are cleaned; secondly, leveling andexcavating the cleaned roadbed ground. According to the construction method for highway subgrade treatment, quality detection is conducted while construction is conducted, and the quality of the constructed highway subgrade can be guaranteed; meanwhile, through repeated compaction, the compactness of the subgrade is guaranteed, local settlement is avoided, the strength stability of the whole structure is guaranteed, long-
