Abstract:In June of 1989, the Texas Department of Transportation (TxDOT) contracted with the Texas Transportation Institute (TTI) to develop a set of performance specifications for truck mounted attenuators (TMA's). The objectives of this project were to (1) assess the performance of several truck mounted attenuators and then (2) develop and propose the criteria that define an "acceptable" TMA. These criteria will be used by the Equipment and Procurement Division (D-4) of the Texas Department of Transportation in setting minimum performance requirements for TMA's purchased by the Department. This report is the third of three volumes. The purposes of this report are to (1) describe the procedures for conducting vibration and moisture tests on TMA's, (2) discuss the plans for the construction of the necessary apparatus to conduct these tests, and (3) explain the procedures and protocols by which these tests are conducted.
