Which is compact for single steel wheel roller and double steel roller?
At present, the double steel wheel is mainly applicable to the compaction of the surface layer or the thinner compaction condition. The base layer or the thicker layer shall be better than the large tonnage single steel wheel.
Single steel wheel and double steel wheel are suitable for different construction conditions, which can not be simply said which kind of compaction effect is good.
I suggest you go to Luoyang, Jin Xiao! He sells both steel wheels and single steel wheels, so you can get to know them!
