Why should not be modified asphalt mixture roller compaction, and dense asphalt mixture should be used tire roller compound pressure?
Caused by tectonic depth decreases, and even bleeding. It is generally used vibroll is better.
The modified asphalt mixture are generally due to discontinuous gradation, rub tire roller will make the coarse aggregate float.
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.
