Description

Technical Field

[0002] The paving method of graded crushed stone refers to the paving method of graded crushed stone on urban roads or highways, which is determined according to the project requirements and technical specifications, mainly including coarse aggregate, medium aggregate and fine aggregate, as well as stone powder. The specific proportion will be set according to the specific requirements of the project, the properties of the materials and the expected performance, and finally mixed for use.

[0003] Usually divided into manual paving and mechanical paving. When preparing for manual paving and mechanical paving, the surveyor will lay out the construction lines to measure the elevation, and draw lines in the middle and edge of the roadbed according to the measured elevation. After that, the manual paving will lay graded gravel according to the height of the lines.
