Thin Wearing Courses

In the future the maintenance and expansion of available road networks worldwide will increasingly play an important role.
In Germany alone this network is made up of 626,820 kilometers (Ebner 2006) of roads.

Here as in other places, funding is often lacking to adequately maintain this network. That is why it is especially important to have and use economically advantageous, and at the same time, technically satisfactory construction methods for road maintenance.
In Germany the appropriate construction methods for this maintenance for the various conditions of the roads are described in the "ZTV BEA-StB" (Supplementary Technical Conditions of Contract, Specifications, and Guidelines for Structural Maintenance of Traffic Areas" Asphalt Construction Methods). Without going into the various possibilities contained therein, it has been determined from extensive, available practical experience that thin surface courses paved using hot application, have proven to be outstanding when allowances are made for the technical and economic aspects.

Here thin wearing courses paved using the Stone Mastic Asphalt principle play a special role
