Abstract:
The paper aims at underlining the important role of the foundation soil in producing and deteriorating the degradations on DN 57 on the section between km 153+000 and km 158+000. To this purpose, a relatively large number of field and laboratory geotechnical investigations have been realized. The correlation of the high activity potential of the clay layer immediately under the road pavement with the preponderance of the road degradations such as longitudinal cracking, led to the conclusion that the high thermal and pluviometric variations cumulated with the active and very active character of the clay in the road bed was one of the causes leading to the occurrence and development of degradations on the investigated road section.
