This report presents the findings of the test programs, simulations, and analyses performed to determine the requirements for the effective application of berms and guardrails as truck restraint systems for elevated mine roadways. Included are criteria for effective vehicle restraints for guardrail applications and recommendations for berm applications based on scale model tests and computer simulations. Full-scale haulage vehicle-berm interaction field tests were performed to correlate the results of these model tests and computer simulations. Recommendations for the construction of berms were made on the basis of tests of bermbearing strength, response of the vehicle to different berms, and predictions based on the obtained correlation.
