Asphalt concrete highway reconstruction and extension roadbed lap joint construction process
The invention relates to the technical field of civil engineering, and discloses an asphalt concrete highway reconstruction and extension roadbed lap joint construction process, which comprises the following steps of measuring and measuring the center line of an original highway roadbed, determining the overall center line of an extended highway, determining the range of a new roadbed, and carrying out labeling and positioning. The asphalt concrete highway reconstruction and extension roadbed lap joint construction process comprises the following steps of: determining a new roadbed range; clearing a whole section and excavating in a verified new roadbed range, completely removing garbage, organic matter residues, demolition residues, waste structures, turf within 20 cm below the original ground, root systems of crops, tree roots, surface soil and sludge in the roadbed range, adopting an excavator to take earth nearby to fill and level a sunken place, tamping the soil by using a road roller or the excavator after the filling and leveling, leveling the inclination in the section, leveling the lower part of the side close to an old roadbed by using a filling method, keeping away fromthe lower part of the old roadbed and being close to a broken slope, enabling the overlapped new roadbed to be not easy to sink and achieving good construction quality.
本发明涉及土木工程技术领域，且公开了一种沥青混凝土公路改扩建路基搭接施工工艺，包括以下步骤，测量，测量原有公路路基的中线，确定出扩建后公路的整体中线，确定新路基的范围并插标定位。该沥青混凝土公路改扩建路基搭接施工工艺，通过在核定的新路基范围内，清理整段，开挖，路基用地范围内的垃圾、有机物残渣、拆迁遗留物、废弃结构物、原地面以下20cm以内草皮、农作物的根系、树根、表土和淤泥全部清除，凹陷的地方采用挖掘机就近取土填平，填平后使用压路机或挖掘机夯实，修平整段内的倾斜，靠近老路基一侧低洼的使用填方法修平，远离老路基一侧低洼且靠近断坡的，搭接的新路基不易下沉，施工质量好。
