0引言目前,国内外对于沥青路面局部破损的养护方法主要是坑槽修补,这种修补方式相对于利用加热板对局部路面加热软化后修补的方式,无论在修补后的路面质量还是在使用寿命上都更为突出。早期使用的坑槽开挖设备有切割机、风镐和人力镐等,利用这些设备开挖坑槽工作效率低,劳动强度大。笔者根据发明专利《沥青路面圆形坑槽铣刨设备》对沥青路面圆形坑槽铣刨机进行研发,其目的在于研发出一种能直接铣刨出形状规则、边缘垂直的圆形坑槽铣刨机。
0 Introduction At present, the domestic and international methods for the maintenance of local damage to asphalt pavement are mainly pit repairs. Compared with the method of repairing the local pavement by softened surface by hot plate, no matter the quality of repaired pavement or service life On the more prominent. Early use of the pit excavation equipment cutting machines, picks and picks, etc., the use of these devices excavation pit work is inefficient, labor-intensive. The author of the invention patent “asphalt pavement circular groove milling equipment” on the asphalt pavement circular groove milling machine research and development, the purpose is to develop a can be directly milled out the shape of the rules, the vertical edge of the circular pit Milling Machine.
