Semi-rigidity and semi-flexible highway extension splicing structure and construction method

The invention discloses a semi-rigidity and semi-flexible highway extension splicing structure and a construction method, and belongs to the field of road engineering. A framework is laid in a gradingdetritus layer of a new road of the semi-rigidity and semi-flexible highway extension splicing structure, and is used for restraining aggregates. The construction method of the semi-rigidity and semi-flexible highway extension splicing structure gives the construction principle of a semi-rigidity and semi-flexible base layer and a grading detritus layer. The semi-rigidity and semi-flexible highway extension splicing structure is characterized in that the framework of a specific structure is added to the grading detritus layer of an expanded pavement; the mechanical property of the grading detritus layer is effectively improved, so that the damage such as reflecting cracks during the service of the extension highway can be reduced. The construction method of the semi-rigidity and semi-flexible highway extension sp
