Preventive maintenance-Construction of ultra-thin asphalt overlay

As China's road industry gradually turned to maintenance-oriented.、Phase supplemented by new construction，Road preventive maintenance is a new concept of pavement maintenance.。As one of the most cost control forward-looking technologies in preventive maintenance,，The construction of ultra-thin asphalt overlay is more and more widely used.。

Baomag experts aim at the characteristics of rapid temperature loss during the construction of ultra-thin overlay.，Roll-out of front-steel and rear-rubber combined roller——BW 161 AC-4，The rolling can be completed at a higher temperature.，But also can avoid leave a wheel mark.，Reduced surface porosity，Improve compaction surface quality，It is the first choice for thin overlay construction.！

With years of experience in construction application，Baumag came up with the solution.，Change construction equipment to：One 13-ton heavy-duty tandem vibratory rollerBW 203ADO+OneBW 161AC，After changing the rolling equipment collocation，BW161ACIt is equivalent to the simultaneous construction of two equipment.，By virtue of the high static linear load of the front steel wheel and the rubbing action of the rear rubber wheel，The surface porosity is reduced while the compactness is significantly improved.。It not only reduces the number of equipment used.、But also save personnel cost and fuel cost.。
