GEOTEXTILES FOR THE CONSTRUCTION OF A MOTORWAY, A-45 BETWEEN GIESSEN AND HANAU, GERMANY

This short case history describes four full-scale trials, conducted on the A-45 motorway in Germany between 1974 and 1977, to determine how geotextiles work and whether they were suitable. In the first trial, several different nonwoven geotextiles were installed in a temporary embankment up to 1.2m high, to compare their ease of handling and their behaviour during aggregate placement and under subsequent traffic loads. During the later trials, the influence of geotextiles on the bearing capacity of a granular layer was studied. In 1975, a trial embankment was constructed in the Horloff valley, to test the behaviour of the valley's soils under the embankment fill. Investigations were made of: (1) the speed of settlement; (2) the effect of compaction equipnment and construction traffic on the subgrade soil; (3) the influence of different embankment heights on the subgrade; and (4) the influence of geotextiles on the subgrade/embankment system. In the final motorway construction, nonwoven geotextile was used to separate the soft subgrade and the embankment base layer. Geotextile strips were laid across the embankment's axis, and overlapped by about 500mm. For the covering abstract see IRRD 865821.
