The truck cab contains an on-board computer system that controls all skid friction testing operations and performs all necessary data logging functions. The computer system, herein referenced as the Mobile Data Recorder (MDR), in conjunction with the remaining components of Pave®Lok, are capable of:
(a) Interfacing with the operator
(b) Controlling the tests
(c) Measuring and digitizing the necessary resultant test signal data,
(d) Recording the resultant test data on IBM-PC compatible media
(e) Calculating and storing the friction values
(f) Displaying the stored digitized friction data
(g) Printing the stored data upon operator request
