小型壓路機在碾壓時預防措施

　　瀝青結合料提高了鋪路用粒料抵抗行車和自然因素對路面損害的能力，使路面平整少塵、不透水、經久耐用。因此，瀝青路面是道路建設中一種被廣泛采用的gao級路面。接下來由通華機械小編介紹小型壓路機在碾壓時的預防措施：

　　1、先輕后重。開始土體松軟，小型壓路機碾壓太重，造成土體堆積，厚度不均，壓實度也得不到保障。故先用輕壓路機，將土體均勻壓實，等路基土體有一定強度后，用重壓路機碾壓，至要求壓實度。

2、小型壓路機碾壓應先兩邊后中間、先內側后外側。先兩邊后中間這是針對直線路段，橫坡設置是中間高兩邊低，先低后高。先內側后外側這是針對曲線超高路段，內側低外側高，小型壓路機型號規格，先低后高。

　　手扶壓路機的振動效果可以增強的壓實效果，將油門加大壓路機振動，油門到怠速壓路機手靜碾。當壓實非常松散或柔軟的材料時，第1遍壓實使用靜碾，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.

使用振動壓實，已達到所需要的效果。

　　再為大家介紹一個小型壓路機通用的操作小技巧

　　無論是上坡碾壓還是下坡碾壓，壓路機的驅動輪均應在后面。上坡時，后面的驅動輪可以承受坡道及機器自身所提供的驅動力，同時前輪對路面進行初步壓實，以承受驅動輪所產生的較大的剪切力;下坡時，壓路機自重所產生的沖擊力是靠驅動輪的制動來抵消的，只有經前輪碾壓后的混合料才有支承后驅動輪產生剪切力的能力。
