公路沥青路面施工技术规范实施指南
英文回答：
Asphalt Pavement Construction Technical Specification Implementation Guidelines.
1. Preparation.
Comply with design requirements and ensure construction site conditions meet specifications.
Establish quality control system and conduct material testing and inspection to ensure material quality meets standards.
Train construction personnel on technical requirements and safety procedures.
2. Subgrade Preparation.
Excavate and shape subgrade to desired grade and compaction level.
Install drainage systems as per design to prevent water infiltration.
Stabilize subgrade if necessary to enhance bearing capacity.
3. Base Course Construction.
Place and compact base course material to specified thickness and density.
Use proper equipment and techniques to achieve uniform compaction.
Ensure base course has adequate strength and stability to support traffic loads.
4. Asphalt Paving.
Determine asphalt mix design and temperature based on traffic conditions and environmental factors.
Place asphalt mix using paver and ensure proper compaction using rollers.
Adjust roller patterns and compaction parameters to achieve desired density and smoothness.
5. Joint Construction.
Construct joints at specified intervals or as per design.
Use asphalt tack coat or joint sealant to ensure proper bonding between asphalt layers.
Compact joints thoroughly to prevent water
infiltration or raveling.
6. Surface Treatment.
Apply surface treatment as per specifications to enhance skid resistance and durability.
Options include chip seal, slurry seal, or micro surfacing.
Ensure surface treatment is applied evenly and compacted properly.
7. Inspection and Acceptance.
Conduct final inspection to verify compliance with technical specifications.
Test asphalt pavement properties (e.g., density, thickness, smoothness) to ensure quality.
Issue acceptance certificate upon satisfactory completion of construction.

公路沥青路面施工技术规范实施指南。

1、准备工作。

遵守设计要求，确保施工现场条件符合规范。

建立质量控制体系，对材料进行检测检验，保证材料质量满足标准。

对施工人员进行技术要求和安全施工程序的培训。

2、基层施工。

开挖并整形基层至设计标高和压实度要求。

按设计安装排水系统，防止水渗入。

必要时对基层进行稳定处理，增强承载能力。

3、基层施工。

摊铺并碾压基层材料至规定的厚度和密度。

使用合适的设备和技术，达到均匀压实。

确保基层具有足够的强度和稳定性，以承受荷载。

4、沥青摊铺。

根据交通状况和环境因素确定沥青配合比和温度。

使用摊铺机摊铺沥青混合料，并用压路机碾压至适当的密实度。

调整压路机碾压方式和压实参数，达到预期的密度和平整度。

5、接缝施工。

在指定间距或按设计施工接缝。

使用沥青粘层剂或接缝密封剂，确保沥青层间有良好的粘结。

对接缝彻底碾压，防止渗水或松散。

6、表面处理。

根据规范要求应用表面处理，以提高防滑性和耐久性。

可选择表面撒布、灌浆封层或微表处。

确保表面处理均匀摊铺，并压实妥当。

7、检验验收。

进行最终检验，核实是否符合技术规范。

检测沥青路面的性能（如密度、厚度、平整度），以确保质量。

在工程圆满完成后，签发验收证书。
