Welcome to Dr. Chun-Hsing (Jun) Ho Construction Materials Lab

(Our team won First Overall Place , Second Place, and Third Place in the Student Poster Competition at the 2014 Arizona Pavements/Materials Conference)

The Construction Materials Lab at Northern Arizona University has been grown increasingly in the past years. The student population contains a variety of backgrounds from the US, China, Kuwait, Brazil, and Nigeria. We are a global research community. The Materials Lab has been in collaboration with ASU, Navajo DOT, Hopi DOT, ADOT, the City of Flagstaff, and local consulting firms. Interested students are welcome to join us.

The Construction Materials Lab at Northern Arizona University studies mechanical and physical properties of construction materials (concrete, asphalt, and composite) and their applications in the field to promote the sustainability of the pavement systems. Students who work in the lab have access to the latest information related to construction materials as well as to network with professionals.

Upon his arrival at NAU in August 2012, Dr. Ho has worked with agencies to seek grant supports to upgrade the lab equipment. The lab is currently equipped with a bending beam rheometer (BBR), two dynamic shear rheometers (DSR), a Superpave capable gyratory compactor, a freeze-thaw apparatus (in compliance with ASTM C666), a heavy duty oven, and a materials mixer (concrete and asphalt). Students/professionals interested in working with the lab members are encouraged to contact Dr. Ho at chun-hsing.ho at nau.edu
