Q:Is it necessary to use the rubber tyred roller to crush the upper layer of the asphalt concrete pavement?
The asphalt aggregate ratio and slag amount is more than 6% SMA can not use leather wheel, this is the result of the test section, the rub mastic floating that the depth of the surface structure reduces in this case leather wheel, skid resistance is reduced, skin wheel function is rubbing that is dense, so more suitable for dense graded mixture.
Q:What is static roller mill and what's the difference between vibratory roller and vibratory roller?
It's the wrong place. The roller compactor is just compacting the road through the weight of the roller.
Q:What's the use of this roller? What is the difference between a roller and an ordinary roller?
This is a convex block roller, is adding a layer with a convex block device mounted on the original circular surface of the base, consisting of two semicircle. This roller is mainly used for the compactness of roadbed. In general the main base material is not easy to be smooth when compacting it will be used
Q:What are the major components of a vibratory roller?
There are several kinds of vibratory rollers: single cylinder wheel, double steel wheel, rubber wheel and so on.
Q:Roller roller steel what material? Thickness 10mm or so, which expert pointing Q235, OK?
Thickness of 10? A little thin, more than 20, at least, how can Q235 do it? Can the surface hardness be reached?! Use Mn16 high manganese wear resistant steel! Casting, water toughening. (at least Mn13.)-------------------------
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:Why should we use the rubber tyred roller in the construction of the asphalt pavement?
At present, the latter two are widely used in construction.The following is a steel wheel roller, which is in front of the paver. The following table shows two rubber tyred rollers. Roller's purpose: 1. to achieve the required density (usually controlled by compaction); 2. press out the smooth surface.General compaction includes initial pressure, re pressure and final pressure. The final pressure is to remove the traces of rollers, the road is kept smooth, generally can not be omitted, and the use of steel wheel roller. If the initial pressure can meet the density requirements, there is no need to re pressure, but generally still maintain these three steps.
Q:What is a roller?
The road belongs to the road equipment in construction machinery category, widely used in Embankment Compaction of highway, railway, airport runway, dam, stadium and other large projects, can crush sand, semi viscous soil, the stability of subgrade soil and asphalt concrete road surface
Q:How does the municipal asphalt pavement budget do not have a wheeled roller?
you can audit and said, don't fixed costs, change according to the market price of Jixietaiban, and don't forget the large machinery import charges.
Q:Building construction, taking vibratory compactor as an example, illustrates the method of compaction Matters to be attended to?
Compaction method has three principles: (1) first light and heavy: (2) first slow, then fast; (3) first low and high;It should be noted that: (1) the time of compaction, soil base must be appropriate water content, asphalt mixture temperature appropriate.(2) the role of the regulator - first slow and stable, is to maintain the new layer without deformation:(3) crown holding by low in high RCC will guarantee;(4) asphalt mixture rolling - watering appropriate, non stick office building, but quickly cool down
