气动压路机 3D模型

The use of a pneumatic roller (or rubber tire roller) is vital in the compaction process of asphalt paving, in that, it is able to conform to the surface being paved. Steel drum rollers do a great job in the initial phase of rolling, but they also bridge some areas of the asphalt mat being laid, whereas, the pneumatic roller kneads the hot mix asphalt, working each of the 9 oscillating tires into the asphalt mat. Not only does this achieve denser compaction, but it also drives the bigger aggregate in the mix down, and brings the fine aggregate to the top, actually sealing the asphalt better to eliminate voids and preventing water intrusion. Texture of grill is included in 2048 x 2048 resolution and in PSD format. Highly detailed and optimized 3d model of pneumatic roller. Includes HDRI lightning map. Units are in centimeters.
