Abstract
A “Smart Runway” project was recently undertaken in Utah through the efforts of the Engineer Research and Development Center (ERDC) of the US Army Corps of Engineers to install advanced sensors into a runway pavement test section and monitor pavement responses and damage accumulation over time due to trafficking with critical aircraft systems. In support of the “Smart Runway” project, laboratory tests were conducted on the subgrade, subbase, and base materials obtained from the Hill Air Force Base (AFB) runway pavement, including grain size distribution, image-based shape analysis, anisotropic resilient modulus tests using an innovative UIUC-FastCell test device, and triaxial shear strength tests. In this paper, the laboratory characterization test results are presented and utilized to verify the field response measurements as obtained from Bender Element (BE) shear-wave transducers and Heavy Weight Deflectometer (HWD) tests. A linkage was established between laboratory and field-testing results through advanced testing, materials characterization, and analysis approaches.

The National Science Foundation funded the Geotechnical Women Faculty (GTWF) Project in 2016 to promote gender parity amongst geotechnical engineering professors in the United States. The GTWF Project has, as part of its efforts, built a database of tenured and tenure -track faculty. This database was first created in 2016 at the start of the GTWF project, and recently XSGDWHG E\ WKH WHDP LQ 7KH UHVXOWV DUH ³VQDSVKRWV´ RI WKH ILHOG DW WZR SRLQWV LeQ2 W0LP6 DQG WKDW FDQ WKHQ EH FRPSDUHG WR DVVHVV WKH HIIHFWV RI LQLWLDWLYHV WR LQFUHDVH WKH ILHOG¶V gender diversity. The data also allow the status of US -based female faculty in the geotechnical field specifically to be compared to broader trends in Civil Engineering as a whole. Further, data are presented regarding inclusion in the field of geotechnical engineering through a look at IHPDOH IDFXOW\¶V VKDUH RI $6&( DZDUGV FRPPLWWHH FKDLUV DQG XQLYHUVLW\ GLVWLQJXLVKHG OHFWXUH series. Initial results show that the field of geotechnical engineering still lags behind when compared to civil engineering as a whole, and that placement of women in tenure -track faculty positions has grown only slightly since 2016. Participation data paints a picture of a field starting to see the recognition of women in the field, with female faculty receiving a higher percentage of awards for those under 35, and increasing numbers of female tenure -tracked faculty. These data indicate that efforts over the past decade to increase gender parity are meeting with real -world impact that has seen the field add female faculty at a rate well above the average for Civil (QJLQHHULQJ DV D ZKROH EXW WKDW PRUH QRZ QHHGV WR EH GRQH WR VXSSRUW ZRPHQ¶V UHFRJQLWLRQ DQG inclusion in the field. A follow -up survey in 2025 is also proposed to further assess the changing state of the field. While the widespread nature of these discussions over the past year are welcome, the discussions themselves, about the overrepresentation of white men in STEM and attempts to increase diversity, are nothing new (for example: Bhatia, 1989) . In 1989, the National Science Foundation (NSF) sponsored a workshop of all fema le JHRWHFKQLFDO IDFXOW\ IRU GLVFXVVLRQV RQ VXSSRUWLQJ DQG LQFUHDVLQJ ZRPHQ¶V UHSUHVHQWDWLRQ LQ WKH field. There were seven women geotechnical faculty present. Through the 90s and 2000s, in line with general trends in the academy and society more broadly, t he number of women in the geotechnical field steadily increased. While the number of women in the field has certainly increased in the decades since, there is no central count of geotechnical faculty demographics. The American Society for Engineering Education (ASEE) publishes yearly snapshots assessing the demographics of engineering subfields, but geotechnical, as a specialty of the subfield civil engineering, is not among them. Three hundred and eight universities in the United States offer Civil Enginee ring degrees ( Dept. of Education, n.d.) , out of which we identified 181 that employ tenure or tenure -tracked faculty in the subfield of geotechnical engineering. U.S. institutions graduated 17,102 students in the year 2016 in the field of civil engineering, increasing to 20,056 just four years later in 2020. Of those 2016 graduates, 24.4% were female; LQ ZRPHQ¶V VKDUH KDG LQFUHDVHG WR MXVW RYHU D TXDUWHU DW 6LPLODU JURZWK ZDV SUHVHQW LQ ZRPHQ¶V UHSUHVHQWDWLRQ LQ FLYLO HQJLQHHULQJ DPRQJVW WHQXUHG RU WHQX-UtHrack faculty: from 18.4% in 2016 to 19.6% in 2020 ³(QJLQHHULQJ E\ WKH 1XPEHUV ´ ? <RGHUA s we have demonstrated previously (S.

In 2016, the Geotechnical Women Faculty (GTWF) Project received funding from the NSF an aim to lowe" r isolation of female faculty in geotechnical engineering by creating and sustaining a supportive national network that driv HV FDUHHU VXFFHVV LQ DFDGHPLD´(GTWF, 2016) . The GTWF project pursued this by offering seed grants to women faculty, which required first the identification of eligible faculty ²the creation of the first U.S. Geotechnical faculty database in 2016 (Alestalo et al., 2015; P. Gallagher et al., 2019 ; P. M. Gallagher et al., 2018; D. F. Laefer & McHale, 2010) . In 2018 the database was refreshed, with new faculty identified and faculty ranks adjusted. The same process was repeated in 2021, giving us the ability to spot changes and growth in geotechnic al demographics, numbers, and rank. This paper will discuss the 2021 database, and with the changes observed between 2016 and 2021. We will go over the methodology that was employed to create a directory database of U.S. faculty, and introduce some shortcomings and caveats around the data before we discuss the UHVXOWLQJ ³VQDSVKRWV´ LQ GHSWK ,Q DGGLWLRQ WR SUHVHQWLQJ D ³6WDWH RI WKH )LHOG´ ZLWK UHJDUGV WR JHQGHU GLYHUVLW\ ZH KDYH collected historical data for awards, prestigious university lecture series, and editorial positions for the field from 1990 through 2021.
