Highway pavement subbase construction method
The invention relates to a highway pavement subbase construction method, and belongs to the technical field of building construction. The method is used for improving the strength of gravelly soil andimproving and utilizing an existing soil source to enable an originally substandard material to reach the technical standard of a subbase material of a pavement. According to the construction method,30% of gravels are doped into 70% of gravelly soil according to a mass ratio, the gravelly soil is improved, a land leveler and a road roller are matched to stir and compact the mixed gravelly soil and a gravel mixture, the mixed gravelly soil and original gravel particles in a soil body jointly form a framework structure, a bearing capacity of the soil body is improved, and deformation resistance of the subbase is enhanced. The actually measured deflection value of the gravelly soil subbase after the gravelly soil subbase is improved by mixing the gravelly soil is obviously improved, and thegravelly soil subbase improved by the gravelly soil is more compact in structure.
本发明涉及一种公路路面底基层的施工方法，属于建筑施工技术领域，用于提高砾石土的强度，改善并利用现有土源，使原本不达标的材料达到路面底基层材料的技术标准。该施工方法，按照质量比在70％砾石土中掺入30％碎石，进行砾石土改良，并采用平地机和压路机配合对掺配好的砾石土与碎石混合料进行翻拌及压实，所掺配的碎石和土体中原有的砾石颗粒共同组成了骨架结构，提高了土体的承载力，从而增强底基层抗变形的性能。砾石土底基层掺配碎石改良后的实测弯沉值明显提高，碎石改良砾石土底基层结构更加密实。
