Abstract:

The Heavy and Overweight Vehicle Brake Testing (HOVBT) program exists in order to provide information about the effect of gross vehicle weight (GVW) and on braking performance testing included service brake stopping distance tests, constant-pressure stopping distance tests, and performance-based brake tests. Tests were performed for various combinations of GVW, initial vehicle speed, brake application pressure, and brake condition (with brakes on select wheel-ends disabled). Analysis of the stopping test data showed the stopping distance increasing with load in most cases (as expected) and showed more braking force being generated by the drive axle brakes than the trailer axle brakes, consistent with previous research. The relationship between initial speed, brake application, stopping distance, and load was found to be highly linear in the low to mid-pressure range, providing the basis for a proposed real-time onboard dynamic brake assessment. This research also provided valuable information regarding areas in which future research might focus.
