Evaluation of Rock Slope Protection Material

摘要

Samples of rock slope protection material were obtained and classified as 'Good' or 'Unsatisfactory' on the basis of visual examination and past performance on installations. Test data for the Durability and Rapid Abrasion tests and for the Durability Absorption Ratio were obtained and analyzed. Specifications for these quality determination methods were established. All of the new methods were more accurate in determining material quality than the l969 Standard Specifications used by the California Division of Highways. Because the Durability Absorption Ratio is the most accurate and shows less tendency to discriminate against some rock types, it is recommended as the Standard Specification for quality control of rock slope protection material.
