Abstract: Use of warm mix asphalt (WMA) can provide a reduced carbon footprint and extended paving season during the construction of airfield pavements. However, lower production temperatures and limited aging make WMA mixes more susceptible to rutting. Hardened binder in reclaimed asphalt pavement (RAP) materials can enhance the rutting resistance of such mixes. The Federal Aviation Administration’s (FAA’s) Advisory Circular (AC) for airfield construction neither provides guidance on WMA applications nor approves the use of RAP in surface courses. Considering this, FAA's National Airport Pavement and Materials Research Center (NAPMRC) embarked on an accelerated pavement testing (APT) study involving WMA and RAP. WMA was used to surface two full-scale test lanes with and without 20% RAP in the surface lifts. The bottom two lifts of those two lanes were paved with the same WMA-RAP mix. Both test lanes were divided into three test sections: North, Center, and South. APT was conducted on the center sections to assess the feasibility of early traffic opening that involved channelized trafficking in descending order of temperature, followed by wander-induced trafficking at a controlled temperature. This paper discusses the two phases of traffic tests and observed sensor responses. The presence of RAP in the surface lift reduced surface rut accumulation consistently in both types of traffic tests.

Learning Objectives:

Attendees can expect to learn the following from this session:

Upon completion, the participant will learn about the ongoing accelerated pavement testing studies at FAA's National Airport Pavement and Materials Research Center.
Upon completion, the participant will know how accelerated pavement testing can be used to replicate airfield loading conditions for a flexible pavement immediately after paving.
Upon completion, the participant will be able to assess the feasibility of using warm mix with rap considering rutting susceptibility during traffic opening.
