Asphalt concrete, commonly known as asphalt concrete, is a mixture of manually selected mineral materials with a certain grading composition, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., mixed with a certain proportion of road asphalt materials under strict control conditions. The construction quality inspection of Jinan asphalt concrete mainly involves the following aspects:
1. Asphalt concrete mix ratio inspection is an important factor in ensuring stable performance and reliable quality of asphalt concrete. During inspection, it is necessary to check whether the mix proportion meets the regulations, such as asphalt content, aggregate mix proportion, filling ratio, asphalt material classification, etc.
2. Quality inspection of asphalt concrete raw materials The quality of raw materials such as asphalt, aggregates, and mineral powder has a direct impact on the performance of asphalt concrete. During the inspection, it is necessary to inspect the quality of raw materials, moisture content, particle size, aggregate content, and other aspects.
3. Inspection of asphalt concrete compactness The compactness of asphalt concrete is an important factor for its stable performance and reliable quality. During the inspection, it is necessary to measure the density, porosity, impermeability and other indicators of asphalt concrete.
4. Surface quality inspection of asphalt concrete The surface quality of asphalt concrete engineering affects its aesthetics and service life. During inspection, it is necessary to inspect the smoothness, flatness, color, and other aspects of the asphalt concrete surface.
5. Asphalt concrete test block test is an important method for testing the performance of asphalt concrete. The inspection shall be carried out from the aspects of compressive strength, shear strength, tensile strength, etc.
When conducting asphalt concrete construction inspection, it is necessary to pay attention to the accuracy and reliability of the inspection method to ensure the safety, stability, and reliability of asphalt concrete.
