Because once paver paving road width is limited, for a wide paved road is required to complete the press several times, to form a longitudinal seam between each strip twice. Longitudinal seams due to hot or cold rolling method seams vary.
Tyred roller is the use of the characteristics of the pneumatic tire to be pressed on the material compaction machinery. In addition it has a vertical compression strength, there is the level of pressure strength, compression strength of these levels, not only acting along the direction of travel
Roller when the roller compacted asphalt concrete mixtures, rollers start rolling the time not later than the mixture spread of 15min, this is because the high temperature of asphalt mixture in the atmosphere under ambient temperature conditions prone to temperature drop, it must control the temperature range.
