So the asphalt pavement construction specification said.There is waterproof good, mainly depends on grading
Q:What is the difference between an impact roller and a vibratory roller?
Vibratory roller is the role of the cement becomes more dense and smooth wheel roller is the role of improving smoothness of pavement, so smooth wheel roller replace vibroll.
Q:What documents do I need to open the road roller?
1, roller operation certificate 2, yes, 3, own registration examination hundreds of pieces, into the training course, then forget it
Q:How big is the 20 ton bottle?
20 tons of roller storage battery should be 2 12V120A, and I hope to be helpful to you.
Q:How about roller Qingdao kotai heavy industry.
Qingdao Ketai roller full production hydraulic type, the hydraulic system of the United States Eaton Saul, hose, imported bearings, the price compared to other manufacturers of hydraulic have great advantages, compared with the whole hydraulic products manufacturers and can only compare it to the specific price, and if the roller machine price is high.
Q:Roller driving skills 100
First of all, be sure to find a good reference, aimed at the past, and the other is to relax and look at the far point. It depends on the big direction so it will be straight up.
Q:The rollers are divided into several types
There is also according to drive mode, drive mode, operation mode to distinguish, such as full drive or after drive, hydraulic or mechanical, and so onFor the rolling vibration of single steel wheel and double steel wheel, but the two in the open when the vibration can also be used for static compaction, static rolling is dedicated to the tyre roller.
Q:How can the asphalt be crushed between the road and the road, and the roller will cut the road along the stone
Be close to the kerb and be careful about rolling, and shall not be too close to the edge.

According to the operating weight divided into micro (1 tons); small (1-6 tons); medium (6-10 tons), heavy (10-14 tons); super heavy (16 tons) pressing wheel distinction: single steel wheel and double steel wheel, three wheel, tire according to the compaction principle: vibratory and static effect of impact roller, roller, roller combination at present commonly used in Engineering: single.
Q:Roller three tons, what kind of good?
It's good for Sakai to vibrate both before and after. Vibration can be separated from front to rear.
