When the surface clinker required for asphalt concrete pavement and black macadam pavement is mixed at a fixed point, the freight required for transporting it to the operation surface is not included in this project and needs to be calculated separately. Petroleum asphalt and emulsified asphalt are listed in the quota of spraying asphalt oil, and the corresponding projects should be applied according to the design requirements.

Description of calculation of road engineering quota quantities:
1, description of subgrade (groove) shaping
(1) System-wide Municipal Quota Volume II "Road Engineering" Chapter 1 Road bed (trough) shaping includes 39 sub-items, such as road bed (trough) shaping, roadbed blind ditch, soft foundation treatment and paving cushion material.
(2) The road bed (trough) shaping project includes artificial digging for high filling and low filling, with an average thickness of 10cm, leveling the road bed, forming the vertical and horizontal slopes required by the design, and compacting with a roller.
(3) For the formation of the side ditch, the types of soil excavated in the side ditch and the labor required for the whole process of digging, cultivating soil, repairing slope and throwing residual soil out of the ditch are comprehensively considered. The residual soil on the slope was abandoned and transported to a place 50 meters away from the subgrade.
(4) The blind ditch quota of concrete filter tube does not include the filter material outside the filter tube.
(50cm pile quota, the pile diameter is 50cm.
2. Subgrade description
(1) System-wide Municipal Quota Volume II "Road Engineering" Chapter II Road subbase includes various graded composite soil subbase with 195 subtitle.
(2) When laying lime-soil foundation, multi-layer soil foundation and multi-layer pavement, the top layer of foundation needs to be maintained, and the maintenance period is considered as 7 days. The water consumption has been integrated into the maintenance quota of the top layer of multi-layer soil, and the water consumption will not be calculated repeatedly when used.
(3) The consumption of subbase materials of various materials does not include the consumption of water. If it is necessary to add water when topping, the amount of water added shall be determined by provinces, autonomous regions and municipalities directly under the central government.
(4) Various materials in the multi-layer soil foundation are prepared according to the commonly used mixture ratio. When the design mixture ratio does not meet the quota, the consumption of relevant materials can be adjusted separately by the provinces, autonomous regions and municipalities directly under the central government, but the consumption of manual and mechanical teams shall not be adjusted.
(5) Lime in lime-soil base is the consumption of quicklime. The amount of soil is a loose square.
(6) There is a subtitle of "every increase or decrease" in the quota, which is applicable to the compaction thickness within 20cm. Compaction thickness above 20cm shall be paved in two structural layers.
