The aim of the current research project is to adjust the EVS-EN ISO 14688-1 and 2 soils classification with the Estonian design guide of flexible pavements 2001-52.
The Estonian design guide of flexible pavements 2001-52 is based on administrative guide BCH 46-83 of the USSR Ministry of Transport Construction. Both guides are using GOST 25100-82 as the basis for the classification of soils. Estonia's accession to the EU pledged to harmonize its legislation with the latter, but the Estonian road design is still the areas using Russian Standard Order-based systems. As the result of the project the Estonian design guide of flexible pavements was adjusted to the European norm.
