in order to increase the pavement permeability, the total mass of not less than 25 tons.
For dense bituminous mixture aggregate due to small and continuous gradation, the tyre roller has the rubbing function makes the compaction layer of particles without destroying and interlocked, uniform and compact. As for modified asphalt mixture are generally due to discontinuous gradation, rub tire roller will make the coarse aggregate surface, causing structural depth decreases, and even bleeding. So generally use vibratory roller is better.
