Fine-grained asphalt concrete is a type of paving material.Fine-grained asphalt concrete is a type of construction material made by processing fine-grained materials as aggregates with asphalt as the binder. The particle size of the aggregates is generally less than 4.75 millimeters, with most being less than 2 millimeters, thus offering a higher density compared to dense graded asphalt mixtures. Fine-grained asphalt concrete can be blended with polymer fibers and other materials to enhance its properties, such as tensile strength.

      The fine-grained asphalt concrete has a wide range of applications, such as expressways, municipal roads, airports, and more.

Fine-grained asphalt concrete, with its high strength, durability, noise reduction properties, and environmental friendliness, is widely used in various road and bridge projects. During construction, strict control over parameters and quality standards is necessary to ensure the quality of the work and to extend the lifespan of the road.
