| Description: | Miscellaneous Paper Abstract: Dow truss web waterproofable landing mat was tested without seals under a 50,000-lb single-wheel load (SWL) with 250-psi tire inflation pressure on a 4-CBR subgrade to determine its life in coverages. The panels were placed at a rate of 822 sq ft per man-hour. The full and half panels sustained 1440 coverages of the above loading on a 4-CBR subgrade. A limited number of mats with seals were tested to evaluate the effectiveness of the seal using a C-5A loading (26,600-lb SWL with 100-psi tire inflation pressure) on a 12-CBR subgrade during a 2-month period while natural and simulated rainfall of over 50 in. was recorded. No structural mat failures occurred; however, the seals leaked during the test. When removed, the seals were torn, dislodged, and distorted. For better seal performance, the seal material should be more durable and resilient. The seals should be positively attached to the mat and less susceptible to distortion. NOTE: This file is large.
