According to the website of Beijing Municipal Engineering Contracting Co., Ltd., it is suggested that Beijing Municipal Engineering Contracting Co., Ltd. explain the pricing rules of road subgrade and pavement in detail for reference:

Detailed explanation of pricing rules for subgrade and pavement:

(1) The quota of road bed (trough) rolling forming includes: within the average thickness range of 10, manually dig high and fill low, level the road bed to form the longitudinal and transverse slopes required by the design, and compact it with a roller.

(2) The roughening of the old pavement is suitable for the projects that need to roughen the old pavement by adding a layer on the old pavement.

(3) When the mixture ratio in the slag-based quota is different from the design, adjustment is allowed, but the labor and mechanical consumption of the quota remains unchanged.

(4) Cement concrete pavement formwork shall be prepared according to longitudinal flat joints. If tongue-and-groove joints are designed, the template shall be multiplied by the coefficient 1.05.

(5) The quota of cement concrete pavement integrates the influence factors of reinforced and unreinforced on work efficiency.

(6) The quota of anti-skid grooves carved on cement concrete pavement is applicable to parking lots, garages, ramps and other projects with special surface treatment.

(7) When the pavement adopts steel fiber concrete, the steel fiber content specified in the design shall be multiplied by the material base price according to the corresponding cement concrete pavement quota to enter the quota base price.

(8) Off-site transportation of semi-finished products is not included in asphalt concrete, cement concrete and base mixture, and shall be carried out according to the corresponding semi-finished product transportation quota.

(9) The asphalt in the quota is petroleum asphalt. When kerosene asphalt is used, the coefficient 1.2 is multiplied by the amount of petroleum asphalt.

(10) When the variety of materials designed in the quota for special pavement treatment is different from the quota, adjustment is allowed, but the labor cost and material cost of the quota remain unchanged.

(1 1) When the material variety and quota of sidewalk block design are different, adjustment is allowed, but the quota consumption remains unchanged. Therefore, expressway has subgrade rolling quota.
