小型压路机在碾压时预防措施

　　沥青结合料提高了铺路用粒料抵抗行车和自然因素对路面损害的能力，使路面平整少尘、不透水、经久耐用。因此，沥青路面是道路建设中一种被广泛采用的gao级路面。接下来由通华机械小编介绍小型压路机在碾压时的预防措施：

　　1、先轻后重。开始土体松软，小型压路机碾压太重，造成土体堆积，厚度不均，压实度也得不到保障。故先用轻压路机，将土体均匀压实，等路基土体有一定强度后，用重压路机碾压，至要求压实度。

2、小型压路机碾压应先两边后中间、先内侧后外侧。先两边后中间这是针对直线路段，横坡设置是中间高两边低，先低后高。先内侧后外侧这是针对曲线超高路段，内侧低外侧高，小型压路机型号规格，先低后高。

　　手扶压路机的振动效果可以增强的压实效果，将油门加大压路机振动，油门到怠速压路机手静碾。当压实非常松散或柔软的材料时，第1遍压实使用静碾，然后再Preventive Measures for Small Roller in Rolling Asphalt binder improves the ability of paving aggregates to resist damages to the road surface caused by traffic and natural factors, making the road surface smooth, less dusty, impervious and durable. Therefore, asphalt pavement is a gao grade pavement widely used in road construction. Next, the preventive measures of small road rollers during rolling are introduced by Tonghua Machinery Co Ltd.: 1. First light and then heavy. At first, the soil was soft, and the small roller was too heavy to roll, resulting in accumulation of soil, uneven thickness and no guarantee of compactness. Therefore, light road rollers shall be used to uniformly compact the soil. After the subgrade soil has a certain strength, heavy road rollers shall be used to compact the soil to the required degree of compaction. 2, small roller rolling should be first on both sides after the middle, first inside after the outside. First on both sides and then on the middle. This is for straight sections. The transverse slope is set to be high in the middle and low on both sides. First low and then high. First the inside and then the outside. This is for sections with super-high curves. The inside is low and the outside is high. The model and specification of small road rollers are low and then high.

使用振动压实，已达到所需要的效果。

　　无论是上坡碾压还是下坡碾压，压路机的驱动轮均应在后面。上坡时，后面的驱动轮可以承受坡道及机器自身所提供的驱动力，同时前轮对路面进行初步压实，以承受驱动轮所产生的较大的剪切力;下坡时，压路机自重所产生的冲击力是靠驱动轮的制动来抵消的，只有经前轮碾压后的混合料才有支承后驱动轮产生剪切力的能力。
