Joaquin B. Hernandez, n/a

Research Engineering/ Scientist Associate II
University of Texas at Austin, United States

Joaquin B. Hernandez is a research associate at the Center for Transportation Research. He obtained a
Bachelor’s degree in mechanical engineering from the University of South Florida. During which he
worked for II-VI in Trinity, Florida. During the four years working for II-VI he performed
experiments and research in optoelectronic systems and semiconductor LASERs. In 2016, he
relocated to Austin, Texas where he joined the Center for Transportation Research and has continued
to work with optoelectronics; conducting research using ultra-high speed lasers, stereo vision, and
other sensors for the purpose of pavement evaluation, specifically, deflection measurements.
Mr. Hernandez has contributed to the development of The University of Texas’ Line Laser Scanner
(LLS), which has been an invaluable tool for the characterization of micro- and macro- texture in
pavement. The work of the LLS was part of a TxDOT research project, 0-6878, Accelerating
Innovation in Partnered Pavement Preservation. The developed device was delivered in two
configurations: one to capture micro- and macro- and a second able of covering a larger area,
capturing macro- texture. The efficiency of the LLS was compared with commercially available
equipment and was found to be superior.
