HIGHWAY ROCKFALL RESEARCH: SECTION 1: PILOT STUDY AND SECTION 2: PROCEDURE MANUAL. FINAL REPORT

This research project is directed at developing and demonstrating a system for cost effectively evaluating and prioritizing highway rockfall hazards statewide. This pilot study produced a prototype computer-based highway rockfall hazard ranking system - "CRASH", which can be used to identify those areas of the state's highway system which have the highest incidences of rockfall accidents, as well as any area which has had a reported rockfall accident since 1976. The existing Oregon rockfall hazard ranking system (ODOT system) was selected and studied to determine if it addressed the varied geologic as well as physical rockfall situations in Colorado. This system was adapted to suit the requirements of our prototype hazard ranking scheme. Implementation of the Highway Rockfall Hazard Evaluation system was demonstrated on five pre-selected areas. The mile in each area with the highest number of reported rockfall accidents, as determined by "CRASH", was ranked using the ODOT system.
