What is the most common type of highway surface worn by vehicle use?

Asphalt pavement is the most common type of highway surface used and worn by vehicle traffic. This is largely due to its several advantageous properties, including durability, flexibility, and the ability to withstand various weather conditions. Asphalt surfaces are designed to handle the stresses imposed by vehicular loads, making them ideal for highways and roads that see a high volume of traffic.

Furthermore, asphalt can be easily repaired and maintained, which extends its lifespan and helps keep it in good condition under constant vehicular use. This is especially important for surfaces that endure diverse environmental stressors, such as freeze-thaw cycles, which can lead to cracking and wear.

While concrete pavement is also prevalent, particularly in urban areas, it is typically not as common as asphalt for the majority of roadways. Gravel roads, while found in less developed areas, do not offer the smooth driving surface that asphalt provides, and brick roads are far less common today due to cost and maintenance issues. Thus, the combination of its properties and widespread use solidifies asphalt pavement as the primary surface worn by vehicular use.
