Treatment method for construction joints in paving process of steel slag asphalt mixture pavement
The invention belongs to the technical field of engineering construction, and particularly relates to a treatment method for a construction joint in the paving process of a steel slag asphalt mixture pavement, which comprises the following steps of: (1) determining the position of the construction joint after the paving is interrupted; (2) a pavement section formed by pavement interruption is cut and cleaned, the cut section formed after cutting is perpendicular to the center line of the pavement paving direction, the pavement section is manually planed and aligned through an air pick, and the planing thickness is the layer paving thickness; (3) preparation before next construction: heating the asphalt mixture of the paved pavement close to the construction joint until the temperature is greater than or equal to 160 DEG C; (4) paving the asphalt mixture at the construction joint; and (5) compacting the asphalt mixture at the construction joint. According to the treatment method for the construction joints in the paving process of the steel slag asphalt mixture pavement, the pavement flatness can be effectively improved, the phenomenon of vehicle bumping at the joints is avoided or improved, and the driving comfort of an expressway is improved.
本发明属于工程施工技术领域，具体涉及一种钢渣沥青混合料路面摊铺过程中施工缝的处理方法，包括下述步骤：(1)摊铺中断后确定施工缝位置；(2)对摊铺中断所形成的路面断面进行切割、清理，使切割后形成的切割断面与路面摊铺方向的中心线垂直：人工采用风镐对所述路面断面进行刨除找齐，刨除厚度为层铺厚度；(3)下次施工前准备，加热靠近所述施工缝处已铺筑路面沥青混合料至温度≥160℃；(4)施工缝处沥青混合料摊铺；(5)施工缝处沥青混合料压实。本发明的钢渣沥青混合料路面摊铺过程中施工缝的处理方法可有效提高路面平整度、避免或改善接缝处存在跳车的现象，有助于提升高速公路行车舒适度。
