本文根据压路机驱动类型的不同,通过对压路机在水平路面与纵坡路段沥青路面碾压时的受力分析,得出压路机驱动方式在纵坡路段沥青路面上、下坡碾压时对路面的影响和差别,并提出了纵坡路段沥青路面碾压的合理建议。对于单一驱动轮情况,建议在水平或小纵坡情况下(如纵坡小于2%),驱动轮在前从动轮在后;当纵坡较大时,从动轮在前驱动轮在后。对于双轮驱动情况,建议当纵坡不大或水平路段(如纵坡小于2%),宜采用前轮驱动,或短时间双轮驱动;而在较大纵坡路段,应采用双轮驱动(下坡双轮制动)。
In this paper, according to the different types of roller driving, through the roller compaction analysis of horizontal road surface and longitudinal slope asphalt pavement roller compaction analysis, draw the road roller driving method on the longitudinal slope asphalt pavement, downhill rolling pavement impact And differences, and put forward reasonable suggestions on the roller compaction of asphalt pavement on longitudinal slope sections. For a single drive wheel, it is recommended that the driven wheel bears the rear in the case of a horizontal or small longitudinal slope (for example, a longitudinal slope of less than 2%). When the longitudinal slope is large, the driven wheel is behind the front driven wheel. For two-wheel drive, it is suggested that front-wheel drive, or short-time two-wheel drive should be adopted when the longitudinal gradient is not large or the horizontal section (such as longitudinal slope less than 2%), and double wheel drive (Downhill two-wheel brake).
