1. In addition to ensuring the compactness of the steel fiber concrete, the vibrating machinery and methods used should also ensure the uniformity of the steel fiber distribution in the concrete.

2. In addition to meeting the road surface smoothness requirements of various traffic levels, the surface of the leveled panel shall not be exposed to upturned steel fibers, and the steel fibers in the depth of 10-30mm under the surface should be basically in a flat distribution state. When using slipform paver or track paver to pave steel fiber concrete pavement, the vibrating frequency of the vibrating bar group should not be less than 10000r/min. The bottom edge of the vibrating bar group should be strictly controlled on the surface of the panel. The vibrating rod group is inserted into the steel fiber concrete of the road to vibrate.

3. When using the three-roller unit to pave the steel fiber concrete pavement, the vibrating rod group shall not be inserted into the steel fiber concrete of the pavement to vibrate, and manual insertion shall not be used. High-power flat-plate vibrator can be used to vibrate and compact, and then vibrating beam can be used for compaction and leveling. The bottom surface of the vibrating beam should be provided with raised edges to facilitate the pressing of surface steel fibers and coarse aggregates. Then use a three-roller leveling machine to smooth the surface. Then use a scraper, scraper or spatula over 3m to level the surface vertically and horizontally.
