Abstract
A wheel rut-resistant carriageway and process for obtaining a wheel rut-resistant carriageway. The wheel rut-resistant carriageway includes at least one rigid base layer, at least one intermediate layer, and a rough upper layer. The at least one rigid base layer has a thickness in the range of approximately 6 cm to approximately 8 cm. The at least one intermediate layer is disposed over the at least one rigid base layer and has a thickness in the range of approximately 4 cm to approximately 5 cm. The at least one intermediate layer has a high void rate allowing for the evacuation of heat by ventilation. The rough upper layer is disposed over the intermediate layer and has a thickness in the range of approximately 2 cm to approximately 3 cm. The process includes applying the at least one rigid base layer having a thickness in the range of approximately 6 cm to approximately 8 cm to a surface. Applying the at least one intermediate layer over the at least one rigid base layer, the at least one intermediate layer having a thickness in the range of approximately 4 cm to approximately 5 cm. The at least one intermediate layer having a high void rate allowing for the evacuation of heat b…
