静压压路机 静压压路机主要分为2种类型:三轮和双轮压路机。传统的三轮式压路机有2个大的驱动轮(后轮)和一个小的转向前轮。现代的三轮式压路机采用3个直径相同的钢轮及铰接转向装置。 压实性能 静线压力 对于普通的10～15t的三轮静压压路机,后轮的静线压力一般在500～800N/cm。在压实沥青过程中,它的静线压力一般超过500N/cm。而前轮的静线压力要比后轮低30％左右,因此,后轮必须压过整个面层以达到均匀的压实效果。现代的三轮式静压压路机若配重相同,则其静线压力也相同,在压实过的面层上具有均匀的压实度并且压实方式简单。
Static pressure roller static pressure roller is divided into 2 types: three and two roller. Conventional three-wheeled rollers have two large drive wheels (rear wheels) and one small steering front wheel. The modern three-wheeled roller incorporates three steel wheels of equal diameter and hinged steering. Compaction performance of static pressure For the ordinary 10 ~ 15t three-wheel hydrostatic roller, the static pressure of the rear wheel is generally 500 ~ 800N / cm. In compaction of asphalt, its static line pressure generally exceeds 500N / cm. The front wheel static pressure is lower than the rear 30%, so the rear wheel must be pressed over the entire surface to achieve a uniform compaction effect. Modern three-wheeled hydrostatic rollers with the same counterweight have the same static line pressure, a uniform compaction on the compacted finish and a simple compaction method.
