| 摘要： | The objective of this research project was to determine whether warm mix asphalt (WMA) technologies can be used by the Arizona Department of Transportation (ADOT) for the production of an asphalt rubber?asphaltic concrete friction course (AR?ACFC) without detrimental effects on performance of the pavement. The study consisted of a laboratory study and the monitoring of a field construction project. Three ADOT?approved warm mix additives (Evotherm, Sasobit, and Advera) were investigated. The study showed that when the additives were used at the manufacturer’s suggested target dosage level there was no negative impact on the durability or the moisture susceptibility of the AR?ACFC as compared to the control (no additive) mix. The field study confirmed that the use of WMA technologies during AR?ACFC construction is feasible with no adverse effects on paving operations. |
