| 摘要： | Studded tire use in Oregon results in millions of dollars of pavement damage annually. Accurate tests are needed to qualify durable aggregate for pavements to resist studded tire damage. The Oregon Department of Transportation (ODOT) currently uses the Los Angeles abrasion test as one of the tests to establish aggregate quality. The LA abrasion test may not adequately represent the aggregate durability. The Micro-Deval test was investigated to determine if it provided a better means of establishing aggregate quality for use in pavements. During the summer of 1999, ODOT purchased a Micro-Deval abrasion tester to evaluate aggregate durability of known and new sources. Test results were compared with measured or inferred performance of known sources. Based on the results of the Micro-Deval testing, it does not appear that the equipment is any more discriminating with respect to aggregate abrasive resistance than the Los Angeles abrasion testing. |
