16、od consists of crushing materials in the existing road into a more homogeneous material that can function as a new base layer on its own,or new materials or binders can be added to achieve the desired properties.Normal milling depth is 20-30 cm.The method is particularly well suited where there are

17、many large stones or protruding rocks(rock nodes)in the existing road mass.Normally,large stones(up to 20-30 cm)and smaller protruding rock nodes can be crushed.The method is also particularly well suited where there are long distances and high costs for the transport of new road material.This method is also more environmentally conscious thus can be a good option.27.
