Abstract: An integral waterproofing system was developed for the extruded aluminum truss web heavy duty mat and a roll test quantity of mat equipped with the system delivered to the U. S. Army Engineer Waterways Experiment Station at Vicksburg, Mississippi. The male-female. side joint is sealed by an extruded neoprene, multi-cavity, hollow, compression type seal. The hinged lever closing action of this joint is used to compress the seal. An enlarged "dog bone" type of locking bar, with identical cavities for containing seals extruded into each of its two horizontal sides, provides the means for conveniently and quickly sealing the joints between adjacent end connectors. Locking bar seals are extruded neoprene, in a multi-cavity, hollow, compression type of design. Locking bars are "loaded" with compressed seals prior to delivery to the field. After locking bars are installed, seals are permitted to expand by removing the retaining strips that have confined the seals in a compressed condition. Mat female corners are sealed by direct abutment of locking bar seal ends against the continuous side seal of the adjacent mat. Mat male corners are sealed by installing a molded neoprene combination cap and plug over the protruding end of the installed locking bar. The most advantageous features of the sealing system are believed to be laying speed and economy. The system can be readily adapted to other types of mats such as XM-18, XM-19, AM-2, and the new 48" x 55-1/2" truss web C-5A mat. Reproducible, original drawings adequate for the procurement of additional mats identical to the roll test mats have been prepared and delivered to the WES.
