PAVEMENT DESIGN UNDER SOFT SOIL CONDITIONS IN VIETNAM

The paper presents the problem of soft soils while designing road pavements for Vietnam. The original data and calculation results for flexible pavements are obtained using RADON software. The calculation the stability factor is presented for the embankment slope with geotextile material reinforcement. Flow charts and initial data are obtained as a result of calculations that show the number of reinforcing layers for various types of geotextile material used in Vietnam. These results are intended for inclusion in a database of typical road pavements designed for soft soils.

Keywords: road pavement; soft soil; database; geotextile; typical road pavement.
