This report describes the design and construction of a two-wheel trailer for measuring skid resistance of roadway surfaces. The trailer was designed to conform to ASTM E274-65T Tentative Method of Test for Skid Resistance of Pavement Using a Two-Wheel Trailer.
The development of the various measuring systems and component parts are discussed in detail in the report along with other general information concerning the tow vehicle and trailer.
As a second phase of this study, some fifty roadway sections throughout the Sate were tested for skid resistance in order to check out the operation of the trailer and to determine the general range of coefficient of friction that exist on the Louisiana highway system. The tests indicated that most of the surfaces exceeded the requirements for friction levels recommended in NCHRP No. 37, "Tentative Skid Resistance Requirements for Main Rural Highways."
This report compares network-level friction measurements obtained with a Sideway-force Coefficient Routine Investigation Machine (SCRIM) and tradition...
In an effort to provide a safer highway system in the State of Texas, the Equipment and Procurement Division shops of the Texas Highway Department are...
