Problems solved by technology

Moreover, the location where cracks occur is a weak load area, and uncontrollable cracks will gradually widen or break under heavy traffic, affecting aesthetics and traffic
[0003] A common way to solve the above problems in the field of construction is to set saw marks on the road surface. This saw mark is generally set when the concrete is solidified enough for workers to operate. However, the width of the saw marks is wide. In order to make the road surface If it is relat...
