山东通华机械生产厂家介绍压路机选型可以根据铺层厚度来选择，如下：

1、在---沥青混凝土路面时，应根据混合料的摊铺厚度选择压路机的重量、振幅及振动频率。通常，在铺层厚度小于60mm的薄铺层上，h好使用振幅为0.35~0.60mm的2~6t的小型振动式压路机，这样可避免出现堆料、起波和损坏骨料等现象;

 when rolling asphalt concrete pavement， the weight， amplitude&vibration frequency of roller should be selected according to the paving thickness of mixture. usually， on the thin pavement with thickness less than 60 mm， it is better to use a small vibratory roller with amplitude of 0.35-0.60 mm， 2-6 t， so as to avoid the phenomenon of stacking， ripple&damage of aggregate.

2、同时，为了防止沥青混合料过冷，应在摊铺之后紧跟着进行---。对于厚度大于100mm的厚铺层，应使用高振幅(可---1.0mm)、6~10t的大中型振动式压路机。

 at the same time， in order to prevent supercooling of asphalt mixture，压路机小型， it should be followed by rolling after paving. large&medium-sized vibratory roller with high amplitude (up to 1.0mm)&6-10t should be used for thick pavement with thickness greater than 100mm.
