A road roller sometimes called a roller compactor or just roller is a compactor type engineering vehicle used to compact soil gravel concrete or asphalt in the construction of roads and foundations Similar rollers are used also at landfills or in agricultureIf the moisture content is too large the material is not easy to dry The wet material will be wrapped and adhered to other materials even wrapping the grinding roller resulting in material accumulation on the grinding disc causing the grinding roller to be difficult to press causing vibration to jump

High strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements By carrying loads more efficiently than normal strength concrete high strength concrete also reduces the total amount of material placed and lowers the overall cost of the structureIf the moisture content is too large the material is not easy to dry The wet material will be wrapped and adhered to other materials even wrapping the grinding roller resulting in material accumulation on the grinding disc causing the grinding roller to be difficult to press causing vibration to jump

May 08 32 Vibration is imparted to the concrete by mechanical means It causes temporary liquefaction so that air bubbles come on to the top and expelled ultimately Mechanical vibration can be of various types as given under 1 Internal Vibration It is most commonly used technique of concrete vibrationMar 24 32 If the vibration is only there with the vehicle moving but goes away when put into neutral it is likely a drive line vibration begin checking driveshaft and rear differential c If the vibration is clearly speed related but not RPM related and it is unaffected by engine speed and transmission gear suspect tires wheels or bearings

High strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements By carrying loads more efficiently than normal strength concrete high strength concrete also reduces the total amount of material placed and lowers the overall cost of the structureThe most critical parameters in any compaction problem are frequency of vibration and the amount of force applied these two drive the third parameter stroke or displacement As a rule of thumb heavier materials respond best to high frequency vibration and the resulting smaller stroke that high frequency vibrators produce
