How can impact rolling be qualified? Technical Specification for Impact Rolling Construction of Impact Roller stipulates that:

National standard GB_T 25626-20 10 Impact roller content 1. The scope data clearly points out that "the road section with average settlement ≤30mm after impact rolling for 20 times in subgrade reinforcement and supplementary pressure test section" is not suitable for impact rolling. In fact, this is a concrete explanation of the impact rolling effect of the impact roller reaching the standard.

The foundation in different areas is affected by environment, soil quality, moisture and other factors, and the settlement is quite different. It is obviously unscientific to measure the impact rolling effect by times, and there are also differences in the same model products of different manufacturers with large impact rollers.

The rolling effect of the national standard 25kj impact roller can meet the requirements of impact rolling construction.
