Tire roller in the rolling process due to the presence of elastic deformation, can play a role in compaction of the material, can make asphalt and other laminate materials sealed to reduce the rain when the road surface down the water seepage. According to China's newly revised national standards, "the construction and acceptance of asphalt pavement" requirements, we must promote the use of large tonnage tire roller asphalt pavement after the re-composting. At present, some provinces have been mandatory in the tender of the highway to use more than 25t heavy-duty tires roller, which should be caused when the user purchase the attention. At present, more than 16 t tire roller YL16, YL20, YL25 and other models.
Tandem double-drum vibratory roller can compact asphalt pavement, but also compacted the cement stabilized gravel layer and the stability of soil, is the construction of high-grade highway main models, should consider the choice of 10t level above, dual drive , Dual-vibration, articulated steering and crab-mounted mechanism. Products with crabs can slide about 120mm or more, when the roller compacted near the curb, the machine needs to turn when the crab line will not use the body to break the curb against the curb. Such products are mainly China-made YZC10, YZC12, YZC16, XD120 models, such as Dina Parker's CC522, Ingersoll-Rand's DD110, DD130, BMW's BW141AD, BW151AD and other models.
The main technical parameters of the roller include working quality, exciting force, vibration frequency, amplitude, climbing ability, diesel engine type and power, etc. In general, the same working quality of the road roller to the exciting force, vibration frequency series, amplitude The wider the range, the stronger the climbing ability, the greater the power of the diesel engine is better, but need to pay attention to the turning radius to a smaller as well, this can be in the construction process storage and steering to bring more convenient conditions. Table 2 lists the frequencies, amplitudes and exciting force values ??to be achieved for different working mass rollers.
