The Mays Ride Meter (MRM) is a combination electrical and mechanical device with the ability to measure and trace the vertical excursions of a car vehicle body relative to the rear axle. The MRM provides a continuous recording chart indicating direction, magnitude and summation of bumps, synchronized with distance measurements and land marks. The chart recorder portion of the device is portable and rests on the lap of the operator seated in the front of the test vehicle. Over the past few years, the Ministry has experimented with various road roughness meters in an attempt to objectively determine the ride values of pavements. In 1973, the Ministry purchased the relatively inexpensive ($1,060 U.S.A. funds) Mays Ride Meter, and installed the device in a 1972 Ambassador station wagon. The Mays Ride Meter was developed by Ivan K. Mays in 1967 and is manufactured and distributed by the Rainhart Company of Austin, Texas. This report documents the Ministry's use and experience with the Mays Ride Meter to date. (Author)
