“…The calculated cut rates ranged from 0.30 to 0.55 ft/min, which is much less than those reported by Bell et al (2019) when similar saw attachments were used. In addition, several teeth were broken during the cutting of each repair.…”

Rapid Airfield Damage Recovery (RADR) technologies have proven successful in temperate and subfreezing temperatures but have not been evaluated in extreme cold weather temperatures near 0°F. To address this capability gap, laboratory-scale and full-scale testing was conducted at these temperatures. Methods developed for moderate climates were adapted and demonstrated alongside methods that used snow harvested on-site as compacted backfill. After only a few days of training, seven experimental repairs were conducted by Canadian airmen at Goose Bay Air Base in Labrador, Canada, and load tested with a single-wheel C-17 load cart. Existing RADR technologies performed adequately despite the freezing temperatures, with the main tactic, techniques, and procedures modification being an increased cure time for the rapid-setting concrete surface material. Compacted snow-water slurry methods also performed well, demonstrating their ability to withstand over 500 passes of single-wheel C-17 traffic after sufficient freezing time.

“…The ASHyd presented a greater maintenance and operations burden due to the onboard motor and hydraulics system, but it did not provide any performance benefits relative to the ASTH. As a result, the ASTH was put forward as the leading screed option at the time and was included in the RADR demonstration at the Silver Flag Exercise Site at Tyndall Air Force Base, FL, in September 2017 (Bell et al 2019). In that demonstration, the ASTH was utilized in addition to the Screed King and magnesium bar screed.…”

Finishing, or screeding, the hot mix asphalt or rapid-setting concrete surface of a crater repair is important for rapid airfield damage recovery (RADR) since it determines the aircraft ride surface quality. The objective of RADR repairs is to expediently produce a flush repair, defined as ±0.75 in. of the surrounding pavement surface, with minimal logistical and personnel burden. Multiple screeds were previously evaluated; the most recent project proposed a prototype design of a telehandler-operated integrated screed for both small and large repairs using asphalt or concrete. This project’s objective was to finalize the prototype design and fabricate and test the prototype RADR screed. The prototype RADR screed was successful for small repairs (8.5×8.5 ft). Large repairs (30×30 ft) were generally successful with modest repair quality criteria (RQC) issues being the only notable deficiencies. Large concrete repair RQC issues were attributed to plastic formwork movement, and large asphalt repair RQC issues were attributed to compaction issues or improper roll-down factors. Methods to mitigate these factors were investigated but should be further evaluated. Overall, the RADR screed was successful from technical perspectives but, functionally, is 600-800 lb overweight. Weight reduction should be considered before entering production.

The rapid repair capability of damaged pavement is an important factor that restricts the generation of air force combat effectiveness in wartime, and the testing technology in the process of emergency repair is an important aspect to reflect the capability, but the current testing technologies cannot meet the use requirements. Based on theoretical analysis and testing practice, the test technologies of committed step in airport pavement emergency repair, such as determination of repair scope, testing of structural bearing capacity and pavement surface characteristics, are compared and analyzed in this study, and suggestions for future development are put forward.
