Definitions
- the present invention relates to a paved road (roadway surface layer), particularly to an asphalt paved road for automobile traffic.
- Today's paved road bodies are composed of a subgrade (bank type) that is artificially embanked and compacted, and an upper structure that is laminated with a base layer and a roadway surface layer.
- the role of the roadway surface is to provide a durable, well-maintained, accessible surface for traffic, while also protecting the underlying substratum from direct weather and traffic forces.
- the roadway surface layer is firmly connected to the base layer and contributes to the support of the entire structure. Basically, it is divided into asphalt surface, concrete surface and paving stone surface, and here the asphalt surface is mainly important.
- the surface layer is usually composed of a surface layer which is usually on the upper side, and a bonding layer disposed between the base layer and the surface layer.
- bitumen a naturally occurring or industrially produced mixture comprising bitumen or bituminous binders and minerals and possibly other aggregates and / or additives
- bitumen exists as a colloidally dispersed two-phase system of solid asphalt and viscous oil and is generally dark in color.
- synthetic binders can also be used for making asphalt.
- binding is used here as a generic term for bitumen, bituminous binders and synthetic binders.
- Pavement roads are exposed to thermal loads and mechanical loads due to weather conditions and traffic volumes, and these loads may cause a variety of failure patterns.
- the binder is plasticized, and this plasticization may cause rut formation along with mechanical traffic load. In this previously damaged area, further cooling with winter In addition, vertical cracks may appear at high mechanical loads. Both thermal and mechanical loads are strong in large cities.
- a situation known as the heat island phenomenon emerges, where in hot midsummer days the temperature in dense areas is much higher than in the surrounding countryside.
- This phenomenon can be attributed to a variety of factors, including high heat dissipation from industry and vehicles, the build-up of incident heat from buildings, reduced convective waste heat from winds as a result of building congestion, and green space. There is a decline in natural cooling via water evaporation due to the decline. Mechanical Perspective In large cities, there is heavy traffic !, that the average speed decreases and the traffic flow is interrupted. The same effect increases with increasing axial load.
- Exhausted heat is ultimately determined by the heat transfer capacity of each layer and subgrade, as well as the roadway structure and thermal boundary conditions.

- the difference due to the solar radiation is the difference in the temperature difference between the surface portion and the base layer portion. (See Figure 5). Since the solar radiation is not applied to the base layer portion, the temperature difference in the base layer portion can be attributed to the difference in the heat conduction effect.
