99 -- PROVIDE REPLACEMENT SUPPORT SYSTEM FOR A HEAVY WEIGHT DEFLECTOMETER TEST SYSTEM POC Randy Brown, 601-634-4119 The USAE Waterways Experiment Station (WES) proposes to award a contract to Dynatest Consulting, Inc., Starke, FL to provide a replacement support system for a Heavy Weight Deflectometer (HWD) - 8081 HWD test system. The tow vehicle will be capable of transporting dynamic cone penetrometer (DCP) equipment, pavement coring equipment, and material to patch holes cored in the pavement during DCP tests and other instrumentation. This support vehicle must be compatible with other WES owned instrumentation (9000 system processor) in support of the HWD. The basic requirements for the tow vehicle are: 7.3 Diesel Engine mounted forward of passenger compartment; Electronic 4-speed automatic transmission; LT 245/75Rx16E tires (5); 4.10 ratio limited slip rear axle; trailer tow Pkg. Class II,III,IV; High capacity AC; Power driver seat; Class IV Hitch, Mount, and Ball; Windows all around, Insulation pkg.; Light and Convenience group; HD alternator; 4 Wheel ABS; Handling Pkg. The most important function of the support system is the interaction provided between it and the 9000 system processor. The 9000 system processor unit is a proprietary piece of equipment, developed by Dynatest, which will be integrated with the support vehicle and the Heavy Weight Deflectometer (HWD). The 9000 system processor, when activated, controls both the support vehicle and the HWD. The 9000 system processor has been specifically engineered to operate the tow vehicle specified. Dynatest is the only source which has the ability to simulate any malfunction and give guidance to field personnel to repair or overcome encountered problems. Dynatest is the only company authorized to repair or upgrade their HWDS. See numbered Note 22. (0326)
