河北唐山市液压转向更方便小型压路机价格图片3吨压路机Select according to the specific requirements of the project. Some projects do not require the ground to be compacted so high, while others require the ground to be compacted very tightly. Some require that the road surface be very smooth, and others require that the road surface be simply pressed down. Different projects have different choices for small roller, so we should know the requirements of the project before choosing small roller.
2. Select according to the material of pavement. Some pavement is to compact stone, some pavement is to compact asphalt, and some pavement is only to compact some soil. These compaction objects are very different, so the demand for small roller is also different, so we should also pay attention to this point when choosing.
3. Choose according to the grade of highway. Some roads are required to reach the first level of the state, some are second level, and some are lower level. You don't have to use very good compactors to compact some roads that only need to reach very low levels in the country, which is wasteful. And if the use of small roller does not meet the requirements, not up to the national level, this is not feasible, so when choosing should take this into account.
