An asphalt pavement refers to various types of road surfaces constructed by mixing asphalt materials with mineral materials. The asphalt binder enhances the ability of the granular materials used for paving to withstand damage from traffic and natural elements, resulting in a smooth, dust-free, waterproof, and durable surface. Therefore, asphalt pavements are a widely used high-grade road surface in road construction, commonly known as "blacktop."

Asphalt pavement construction is a complex and meticulous process, encompassing steps such as old pavement treatment, asphalt emulsion application, geotextile laying, asphalt mixture blending, laying, rolling, joint treatment, and maintenance.

Asphalt concrete is formed by mixing a certain viscosity asphalt material with a proper amount of mineral aggregates of specific gradation. It withstands the repetitive loads of vehicles and long-term environmental influences as a paving material. Due to its excellent performance and wide applicability, asphalt pavement is extensively used in road construction. During the design, construction, and maintenance of asphalt pavements, their characteristics and requirements should be fully considered to ensure the quality and service life of the road surface.
