In the case of a 130 cm thick pavement, the bottom 50 centimetres can first be used to improve and compact the partially non-cohesive, partially cohesive soil with cement. The next layer consists of 15 cm of a solidified mixture of hydrophobic cement and frost-resistant sand. WIRTGEN soil stabilisers and HAMM soil compactors are used for this purpose. A 25 cm thick CTB lies above it. Last but not least, slipform pavers lay a 40 cm thick concrete layer in vertical moulds with a sinusoidal profile.
