In the present thesis an integrated system aiming at the assessment of the failure risk of highway geotechnical assets and the relevant consequences on traffic flow and travelers’ safety is presented. Critical review of the relevant international literature brings out serious gaps and disadvantages of the existing rock mass classification and risk assessment systems. According to the proposed system, the traffic dislocation risk derives from the combination of three factors, a) the stability of earth-structures, where special attention is given to the action of water, this being the most common triggering factor for failure, b) the extent of failure and c) the consequences on traffic flow and travelers’ safety. As regards to the first factor, a separate sub-system for the quantitative assessment of the failure hazard of each type of highway earth-structure is proposed covering the vast majority of the likely failure types. The second factor, that is, the extent of failure, is based on proposed analytical and semi-empirical models. Existing models published in international journals and conference proceedings supplement the system. Finally, the failure extent mentioned above is compared with the width of roadway elements for the assessment of the consequences on traffic flow, whilst the potential velocity impact of vehicle onto the failed mass comprises indicator for the safety of travelers.
