The Geneva - Lausanne moeorway, which was commissioned in 1964, comprises about ~5 km of concrete pavement consisting of 20 cm thick doweled slabs (10m x 4m) resting on a non-stabilized 55 cm thick gravel-sand sub-base (0 -100 mm particle size). The subgrade consists of non-stabilized natural insieu soils as...
Pavement monitoring and heavy maintenance on the Geneva-Lausanne motorway
Maintenance and Rehabilitation of Concrete Roads
For the repair of concrete roads to be effective and economic it is essential to have planned maintenance procedure. Details of such a procedure are to be published in the forthcoming publication "Manual for the Maintenance and Repair of Concrete Roads" ,which is to be adopted for roads administered by...
Recommendation for the maintenance of concrete roads in the Federal Republic of Germany
The "Code of practice for the maintenance of concrete roads" ("Merkblatt für die Erhaltung von Betonstrassen") was published in the Federal Republic of Germany in 1985. It is based on the 1968 edition, but clearly reflects further developments in maintenance techniques, e. g., improved drainage. The code forms part of...
Surface treatment of limestone concrete slab with the chipping technique
Since 1980 the technique of pavement construction with thick concrete slabs has been applied on 100 km of the A.26 motorway (Calais - Reims) in northern France. The concrete employed is made with regional limestone aggregates. In order to counteract lowered skidding resistance due to wear of these materials, a...
Continuous quality control of high performance concretes for road – within the framework of site supervision – using a new field tested BASIC-MC programme
Introduction and statement 'of problems: This paper closes the gap in concrete highway engineering technology by evaluating complex compactionphenomena and by deriving mathematical relationships between the concrete-technological, dynamic (thixotropic- plasticized) and physical parameters. It is based on the latest experience, e.g., including the construction of the concrete pavements of the...
