The invention relates to a road widening construction method. The road widening construction method comprises the steps that S1 surveying and setting out: a construction range and an excavation elevation are determined; S2 surface cleaning excavation: sundries on the surface of a to-be-widened area are cleaned, and then the to-be-widened area is excavated; S3 the roadbed in the widened area is compacted; S4 a broken stone hardcore is laid; S5 connecting plate installation: a semicircular groove is horizontally formed in one side of an old road, then an adhesive is injected into the semicircular groove, a circular connecting plate is implanted into the semicircular groove, the semicircular part of the connecting plate is horizontally embedded into the semicircular groove, and the other semicircular part of the connecting plate is located in the widened area; And S6 widened area concrete construction: a side formwork is installed, then concrete is poured into the widened area to form a new road, and the semicircular part of the connecting plate is embedded into the concrete of the new road. The connecting plate is arranged, and the contact area between the connecting plate and the road is large, so that the integrity of the new and old roads is greatly improved, and the problem of longitudinal cracks caused by uneven stress of the new and old roads is solved.
本申请涉及一种道路拓宽施工方法，包括以下步骤：S1测量放线：确定施工范围及开挖标高；S2清表开挖：清理待拓宽区表面的杂物，然后进行待拓宽区的开挖；S3拓宽区路基压实：S4铺设碎石垫层；S5连接板安装：于旧道路的一侧水平开设半圆槽，然后于半圆槽内注入粘胶剂，并植入圆形的连接板，连接板的一半圆部分水平嵌入半圆槽内，连接板的另一半圆部分位于拓宽区内；S6拓宽区混凝土施工：安装侧模板，然后往拓宽区内浇筑混凝土，以形成新道路，且连接板的一半圆部分嵌入新道路的混凝土内。本申请通过设置连接板，连接板与道路之间的接触面积较大，从而大大提高了新旧道路的整体性，进而缓解新旧路面受力不均引起的纵向裂缝问题。
