Welcome to the Arizona State University chapter of the Institute of Transportation Engineers
ASU - ITE is a group of students interested in entering the transportation field. Our mission is to aid our fellow students in learning more about the profession and finding jobs and internships while at the same time attracting others to the field of transportation. We educate ourselves by attending professional seminars, participating in traffic count opportunities, and taking field trips to local sites of interest. We educate each other through community service and social events, as well as general body meetings.
For internship or job opportunities, check our Careers page!

ASU Transportation Seminar: Thursday 10/12 - Dr. Julie Vandenbossche (Univ. of Pittsburgh) on Bonded Concrete Overlays of Asphalt
Please join us at the ASU Transportation Engineering Seminar this Thursday, October 12, when Dr. Julie Vandenbossche (Univ. of Pittsburgh) will present a seminar titled Development of a Design Method for Bonded Concrete Overlays of Asphalt and Modeling the Debonding Mechanism. The event will take place in College Avenue Commons Room 459 at ASU Tempe campus from noon to 1pm and is open to the public (https://maps.asu.edu/?id=120&mrkIid=62858). For ASU visitors, parking is available at the Fulton Center Parking structure (https://maps.asu.edu/?id=120&mrkIid=65177). More parking locations are available and can be found through theASU interactive map.
ABSTRACT Bonded Concrete Overlays of Asphalt (BCOA) is becoming an increasingly popular alternative for the rehabilitation of asphalt pavements. This is due, in-part, to the development of design tools that have become readily available beginning in 2013 with the release of the BCOA-ME. A subset of the BCOA pavement structures can also now be designed using the AASHTO Pavement ME software. A primary mode of failure for these structures, fatigue cracking, is typically predicated by debonding between the asphalt and the concrete overlay. Partial debonding is assumed to occur in the BCOA-ME design procedure, while the Pavement ME procedure reduces the stiffness of the asphalt layer by 45% to artificially simulate an increase in stress resulting from debonding. Both procedures can benefit from a more rigorous debonding model. To address this limitation, a small scale laboratory studies were conducted to populate a database used in the development of a cohesive zone model in the finite element environment through an inverse analysis. Accelerated loading tests were then conducted on BCOA slabs to simulate the fatigue of the interface bond. This is used to measure the growth rate of the interface debonding so that the framework for a debonding model could be established. The design methodology for the BCOA-ME will be introduced and a summary of the development of the framework for a debonding model will be presented.
