[0002] Roads, in terms of their meaning, are infrastructure for various trackless vehicles and pedestrians to pass through. According to their usage characteristics, they are divided into highways, urban roads, rural roads, factory roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages, and school roads. Roads are an indispensable part of people's lives. After road construction, they need to be tested, especially strength testing. If the strength of the road does not meet the standards, there will be serious safety hazards. The most common practice in road strength testing is to strike the constructed road.
