Download or read book Pavement Evaluation Using Road Meters written by and published by Highway Research Board. This book was released on 1973 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many instruments are available for measuring pavement roughness. Some of these instruments are costly and obtain very detailed data. Most require that pavement condition be measured at low speeds, thus demanding that production rates be quite low. For many years, engineers have been searching for a device that gives the required information but is inexpensive to produce and operate. The road meter, first developed by Max P. Brokaw, is a simple device that essentially measures the relative movement of the rear axle of a passenger car with respect to the frame of the car. This device permits obtaining a large amount of data and can in fact be operated by 1 person in a passenger car, although generally 2 individuals are required. Because the instrument is new, a need has existed to bring together engineers and researchers who are using the device to discuss the experience of various agencies in obtaining pavement condition data by this technique.
