CATALOG OF DETERIORATION OF BITUMINOUS SURFACINGS IN HIGHWAY STRUCTURES

CATALOGUE DES DEGRADATIONS DES REVETEMENTS HYDROCARBONES D'OUVRAGES D'ART

The present report was initiated on the basis of both the information concerning the composition of the bridge pavements obtained through the bridge authorities in charge, and the visual inspection of about 500 bridges scattered throughout the whole Belgium motor-and expressway network. The book gives and definitions, and describes the function and the characteristics of each layer of the bridge pavements, and proceeds to the identification of the observed damage, its classification and the fundamental mechanisms causing the deterioration and its probable evolution. The study goes on by analyzing the factors influencing the appearance or the development of the damage (probable causes). These factors can be classified in five categories, the traffic, the conception of the pavement, its fabrication and laying, the climate and the structure of the bridge. We finally proceed to the repairing problems, two kinds have been considered, the definitive and the provisional repairings. Some 26 degradation index cards close the present catalog. Each index card deals with a definite type of damage under the following headings: description (with photos), mechanism, evolution, probable causes, kind of repairing recommended, and other index cards to be consulted. /Author/
