Fatigue of airport pavements is an important consideration in the analysis of high-traffic pavements. The current pavement condition index (PCI) method of pavement evaluation does not adequately evaluate fatigue cracking of airport pavements and should be considered for modification. Recent field inspections by the authors of Atlanta Hartsfield International Airport, Dallas–Fort Worth International Airport, and Albuquerque International Sunport have shown the fatigue cracking in thick concrete pavements to be prevalent. However, it is not normally recorded in a normal PCI inspection because the crack widths are less than 3 mm (1/8 in.). A properly designed, constructed, and maintained pavement should theoretically fail only in fatigue because all other distresses caused by construction deficiencies, material deficiencies, environmental distresses, and maintenance deficiencies would be avoided. Therefore, it is important for the management of airport pavements that receive high levels of traffic to consider fatiguecracking distress. In practice, it is not possible to sample 100 percent of pavements to fully evaluate all hairline cracking. However, a geographical distribution of pavement control sections can be established and monitored for changes over time. The PCI should be revised or a new distress identification method should be developed to account for fatigue cracking.

This report documents the substantive findings and management recommendations of a cultural resources survey conducted by Integrated Environmental Solutions, LLC (IES) for the DPS Outdoor Bomb and Gun Range project located within the Dallas Fort Worth International Airport (DFW) property in Tarrant County, Texas. The proposed project pertains to improvements of the current facility within approximately 71.8 acres located between Texas State Highway (SH) 360 and West Airfield Drive. Approval from the Federal Aviation Administration (FAA) will be required to modify the Airport Layout Plan (ALP) to reflect the permanent alterations on the DFW property. Since the ALP is considered a federal action, the project will require compliance with the National Environmental Policy Act (NEPA) and Section 106 of the National Historic Preservation Act (NHPA). Additionally, as the DFW is a political subdivision of the State of Texas, the project will be subjected to the provisions of the Antiquities Code of Texas (ACT). The goal of the survey was to locate, identify, and assess any cultural resources that could be adversely affected by the proposed development, and to evaluate such resources for their potential eligibility for listing as a State Antiquities Landmark (SAL) and eligibility for listing in the National Register of Historic Places (NRHP). The cultural resources inventory survey was conducted on 16 December 2019 and 08 January 2020 by Project Archeologists Anne Gibson and Thomas Chapman, and Staff Archeologist Josh McCormick. All work conformed to 13 Texas Administrative Code 26, which outlines the regulations for implementing the ACT, and was conducted under Texas Antiquities Permit No. 9161. During the survey, one previously recorded historic-age archeological site (41TR87) was revisited within the APE. Based on the lack of association with historically important individuals or events, absence of significant architectural features, the degree of prior disturbance, and lack of contextual integrity, site 41TR87 is recommended to remain not eligible for listing in the NRHP or designation as a SAL. Although multi-component site 41TR18 was partially located within the APE, the site was not evaluated during the survey. However, the results from a previous IES investigation in 2015 indicate the site should remain ineligible for NRHP listing. Project records will be permanently curated at the Center for Archeological Research (CAR) at The University of Texas at San Antonio (UTSA). It is the recommendation of IES that the DPS Outdoor Bomb and Gun Range Project be permitted to continue without the need for further cultural resources investigations. However, if any cultural resources, other than those discussed in this report, are encountered during construction, the operators should stop construction activities in the vicinity of the inadvertent discovery, and immediately contact the project cultural resources representative to initiate coordination with the Texas Historical Commission (THC) prior to resuming construction activities.

<div> <p>Precipitation variability from drop scale to regional scale is not fully understood, except we know there is variability at all scales.  The Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) Dallas-Fort Worth (DFW) urban demonstration network consists of a high-resolution, dual-polarized X-band radar network and a National Weather Service S-band radar system for areal coverage as well as a network of in-situ instruments including tipping bucket gauges, and disdrometers in the DFW international airport. Based on the CASA DFW monitoring platform, we have been exploring the rainfall variability across the airport scale of a large airport such as DFW.  We study the variability of precipitation within the airport grounds and the corresponding impact on airport monitoring and regulatory compliance issues. We also extend this variability analysis across the DFW metro which is also considered a large metro region. The particle size distribution and its small-scale variability are analyzed on both heavy and light rainfall events. As for the catchment scale, the spatial heterogeneity of precipitation in the DFW international airport is specially explored. As for the regional scale, the DFW metropolis is used, and its precipitation variability and trends are demonstrated under the DFW urban radar network. Finally, hydrological response to precipitation variability during the rainstorm event in the DFW international airport is discussed. These observations provide an insight into the relation between space time variability of precipitation and practical response activities in an important region such as airport grounds.  </p> </div><div> <p> </p> </div>
