In order to improve the quality and efficiency of construction, the roadbed after the first compaction with vibratory roller, and then the middle of the tire roller compaction, and finally with the light roller to do the final finishing light compaction. Poor condition of the construction unit or highway grade lower requirements can also choose a type of road roller to complete all the construction process, but it should be noted that, if the selection of static roller road roller need to be rolled several times in order to achieve the standard requirements If the tire-driven single-drum vibratory roller is used, the final pavement finishing should be inverted and not vibrated, so that the roller is rolled in the rear to avoid tire indentation on the road surface. Table 1 shows the different soil suitable compacting machinery.
The choice of static roller roller should also consider the larger tonnage of the product, especially for only static roller roller construction users, in order to improve the construction efficiency and compaction quality, the tonnage is preferably not less than 15t, after gravimetric weight Up to 18t or more. Can choose to build the Los 3Y15X18 (X sanding weight after the weight can be achieved), Xugong and Los built 3Y12X15, 3Y18X21 and so on. It is noteworthy that the articulated three-wheeled roller static roller compact as a result of turning radius and drive, better compaction characteristics, by the users of all ages.
