| 摘要： | Once a mix design prepared in the laboratory meets the specifications for performance and has been approved, material-related problems can develop in many places in the plant operation during field production, from stockpiling, cold feed bins, baghouse fines, asphalt mixing, to the storage silo. Field verification, which is verifying that the field-produced hot mix asphalt (HMA) still meets the specifications for performance, is very important. Original field verification data from two Colorado data bases were examined. The volumetric (air voids) and strength (Hveem stability) properties measured during the field verification was related to the rutting performance of the HMA pavements. Four trial projects were constructed using an acceptance specification based on volumetric and strength properties, not gradation. The results are reported here. Additionally, a checklist including eight items was developed to identify potential adjustments in an HMA to account for changes that occur in production through the plant. |
