FULL-DEPTH ASPHALT PAVEMENT DEVELOPMENTS IN GERMAN-DESIGN AND CONSTRUCTION

The theoretical development of Full-Depth pavements is reviewed, and field tests to test the validity of laboratory studies and theoretical calculations are outlined. Details are described of the construction of a test road and of the autobahn project. The required thickness of Full-Depth pavement for German conditions was determined using a limiting value of vertical stress on the subgrade equal to the value used for the standardized pavements. Investigations confirmed that Full-Depth pavements of the calculated thicknesses would be superior to the standardized asphalt pavements with respect to resisting the stresses imposed by traffic loads. Two test fields (4 m wide by 5 m long) indicated that the Full-Depth asphalt pavement structure exhibited less temperature dependency as indicated by less change in stiffness and load carrying capability at all temperatures. The Full-Depth asphalt pavement structure also provided better thermal insulation than the standard structure with a granular base. Field measurements are also being conducted on test roads to standardize the construction and evaluation techniques. The design, construction, evaluation and testing are detailed of reconstructed sections of the Autobahn. On projects where a precise accounting has been made, the costs of Full-Depth pavements have been found to be less costly than other pavement types. Full-Depth pavements can be constructed in less time.
