Pavement Structure – Pavement Interactive
A flexible pavement structure is typically composed of several layers of material each of which receives the loads from the above layer, spreads them out, then passes them on to the layer below. Thus, the further down in the pavement structure a particular layer is, the less load (in terms of force per area) it must carry (see Figure 1).

This material is petroleum in a viscous liquid or semi-solid form. When it is used for pavements and road construction it comes in the form of a composite material, asphalt concrete. Asphalt concrete is about 70% asphalt and 30% aggregate particles. Asphalt is one of the most commonly used materials for road construction for a number of reasons.
Road texture - Wikipedia
Road surface textures are deviations from a planar and smooth surface, affecting the vehicle/tyre interaction. Pavement texture is divided into: microtexture with wavelengths from 0 mm to 0.5 millimetres (0.020 in), macrotexture with wavelengths from 0.5 millimetres (0.020 in) to 50 millimetres (2.0 in) and megatexture with wavelengths from 50 millimetres (2.0 in) to 500 millimetres (20 in).
How Cool Pavements Work | Cool California
New roads can also be constructed using more reflective materials or with permeable paving materials, which keep pavements cooler by absorbing and subsequently evaporating water. In addition to pavement materials, shading from vegetation can keep pavements cooler by preventing the sunlight from being absorbed by the paved surface. Figure 4.
