| 摘要： | The Colorado Department of Transportation (CDOT) has been collecting data from the Hamburg Rutter and the French Rutter for over 20 years. No specifications have been written in that time for either the Hamburg Rutter or the French Rutter. This report looks at the state of practice within other states that own similar equipment. It addresses mixes being produced to pass the Hamburg Rutter being designed too dry. Tests that could be run along with the Hamburg Rutter are examined from a review of literature to determine if there is a suitable companion test for the Hamburg Rutter that would work to keep asphalt levels in the mix high enough to prevent cracking and fatigue. |
