Construction method of cement stone chip stabilized layer:

1) After the roadbed is accepted, the raw materials shall be mechanically stirred according to the design mix proportion;

2) Pave according to the designed thickness, elevation and width, and finally use 8-12T roller to roll until there is no obvious wheel trace.

Construction method of asphalt concrete surface course:

1) Clean the stable layer of stone chips, and then spray the bonding oil;

2) The asphalt concrete of the bottom layer is paved by the way of controlling the vertical and horizontal slope by the way of double baseline and sliding bar, and the 8-12T roller is used to roll from the low end of the runway to the highest part;

3) After the rolling of the lower layer is completed for a period of time, the floating reference beam is used to control the paving of the upper layer, and then the 6-8t roller is used to roll from the lower end of the runway to the highest part until there is no obvious wheel trace.
