NEW DESIGN METHOD FOR SEMI-RIGID PAVEMENTS

摘要

Apartnership project with participation of NCC Contractors, COWI Consulting Engineers and the Danish Road Directorate aims at developing a new analytic-empirical design method for semi-rigid pavements, i.e. pavements with a rigid base layer (normally cement bound) and bituminous wearing course. It is estimated that around 10% of the main road network in Europe are constructed with semi-rigid pavements. The use varies greatly from country to country. France and Germany have a relatively large proportion of semi-rigid pavements, whereas in other countries like Denmark the length of semi-rigid pavements is below 5 % of the total main road network.
