Abstract:

[PROBLEMS] Asphalt pavement exhibiting high reflectivity, heat transmittance and improved thermo-mechanical properties. [MEANS FOR SOLVING PROBLEMS] A pavement (10) comprises at least one asphalt layer (12, 14) containing a mixture of at least one mineral (16, 22) and one bonding material (18, 24), wherein a asphalt surface layer particularly includes one surface layer (14) on the upper side and one bonding layer (12) under the surface layer. At least 60 percent by mass of the one mineral (16, 22) in the at least one asphalt layer (12, 14) is crystalline quartz. Crystalline quartz is employed substantially exclusively as the mineral mainly for the surface layer (14) and the bonding layer (12). The pavement (10) exhibits high reflectivity and heat transmittance under high thermo-mechanical stress and exhibits extremely high safety.
