The paper deals with the assessment of the rockfall risk for a road stretch, in southern Italy, affected by high traffic intensity. Three qualitative rockfall risk rating systems (QRSs) which use an exponential scoring with a base of 3 were employed, and then ...

Current approaches to rockfall hazard and risk mitigation have been dominated by a model in which rockfall is treated as a global slope stability phenomenon which is mainly triggered by precipitation, freeze-thaw, or root wedging. The methods implemented by ...

<p>Despite some preliminary developments for Slope Management Systems (SMS) for the South African Road Network, no functional SMS has been implemented. Slopes along important strategic routes are generally not monitored and only maintained on a reactive basis. ...

The highway between Aswan and Cairo on the eastern bank of the Nile Valley is one of the most used highways in Egypt, connecting most of the governorates with each other. It represents the backbone of Egyptian transportation and commercial traffic. This Highway ...

<p>The purpose of this study was to improve the current Rockfall Hazard Rating System (RHRS) in use by the Colorado Department of Transportation (CDOT) by adding several climatic and geological factors recognized in technical literature that contribute to ...

The proposed rating procedure for rock slopes was presented to the Assistant Commissioner and Chief Engineer, approved, and a working draft issued in May 1993

This paper contains a method for the analysis of rockfall risk along roads and motorways. The method is derivedfrom the Rockfall Hazard Rating System (RHRS) developed by Pierson et al. (1990) at the Oregon State HighwayDivision.
