Technical specifications for asphalt pavement construction refer to a series of technical standards and specifications that must be followed during the construction of asphalt pavement. According to the standard construction, it will control the quality of the project and ensure the effect of the project, which is an indispensable model basis for construction and engineering inspection.

Quality control measures for asphalt pavement mainly include the following aspects:
1. Design stage
In the design stage, it is necessary to accurately measure and calculate the position, linearity, elevation, cross slope, and side slope of the road surface to ensure the accuracy of the design data. At the same time, it is also necessary to consider the impact of climate, traffic volume, terrain and other factors on road construction, and formulate corresponding construction plans.

2. Subgrade construction
The subgrade is the foundation of the asphalt pavement, and its strength, stability and smoothness need to be guaranteed. 
The commonly used methods are filling and excavation. The filling material is generally lime soil, gravel, etc., and the excavation material is generally benign soil or sandy soil. During construction, attention should be paid to controlling the height and width of the subgrade according to the design elevation to ensure the compactness and flatness of the subgrade.

3. Base construction
The base layer is the load-bearing layer of the asphalt pavement, which has a great influence on the service life and driving comfort of the pavement. Commonly used base materials are graded crushed stone, mud stone, etc. During the construction, attention should be paid to the construction according to the design elevation and thickness to ensure the strength and flatness of the base.

4. Production of asphalt mixture
Asphalt mixture is the core material of asphalt pavement, which has a great influence on the quality and service life of the pavement. Commonly used asphalt materials include coal tar pitch, shale pitch, petroleum pitch, etc. Asphalt mixture mixing needs asphalt mixing plant to complete. During production,  should pay attention to selecting suitable asphalt materials, and controlling the mixing ratio and heating temperature of asphalt to ensure that the produced asphalt mixture meets the design requirements.

5. Road construction
Pavement construction is the last process of asphalt pavement, which has a great influence on the appearance, quality and service life of the pavement. During construction, attention should be paid to construction according to the design elevation and thickness to ensure the flatness and transverse slope of the road surface. During the construction process, it is also necessary to pay attention to preventing problems such as dust and vehicle spilling, so as to ensure that the environment of the construction site is clean and tidy.
