Ken Stokoe Elected to ASCE Distinguished Members Class of 2016
Congratulations to Professor Ken Stokoe for being elected to the Class of 2016 of American Society of Civil Engineers (ASCE) Distinguished Members in recognition of his “world-renowned contributions to the understanding of soil dynamics in geotechnical engineering.” Distinguished Membership is the highest honor ASCE can bestow, reserved for civil engineers who have attained eminence in engineering. Stokoe was selected for this honor because engineers worldwide use the resonant column apparatus he developed to assess soil properties. He also adopted and developed cross-hole seismic methods for measurement of in situ wave velocities in soil and rock that won worldwide acceptance. In addition, he developed the spectral-analysis-of-surface-waves method for geotechnical and earthquake engineering applications, now widely used around the world. Notes CAEE Department Chair Rich Corsi, “This is a well-deserved award that underscores Ken’s contributions to his field.”
Stokoe’s considerable contributions to the transportation field most recently include creation of the TPAD (total pavement acceptance device), a new, multi-function pavement testing device developed by a joint effort between CTR, TxDOT, and the Texas A&M Transportation Institute through TxDOT Research Projects 0-6005 and 5-6005-01. The TPAD’s predecessor is rolling dynamic deflectometer (RDD), which Stokoe also led the development of. The RDD has provided TxDOT with valuable pavement structural condition information for many years from continuous pavement deflection profiles. The TPAD’s multi-function features include (1) an RDD, (2) ground-penetrating radar, (3) distance measurement instrument, (4) high-precision differential global positioning system (GPS), (5) pavement surface temperature measurement, and (6) digital video imaging of the pavement surface and right-of-way conditions. The TPAD has already been successfully used to evaluate the remaining life of current pavement, help TxDOT District engineers select optimum rehabilitation schemes, and identify problematic areas over a wide range of pavements, such as hot mix asphalt, jointed concrete pavement, continuously reinforced concrete pavement, and composite pavement. Watch the TPAD at work.
