Giustino, J.M. and Emerson, R.J., Instmmentation of the British Portable Skid Tester, Paper presented at a meeting of the Rubber Division, ACS, Toronto, Canada, May 10-12, 1983. [Pg.953]

The friction of road surfaces is often measured with a skid tester developed by the Road Research Laboratory17 and this has also been widely used on other surfaces and floors, including artificial sports surfaces. It is a pendulum device, the movement of which is arrested by the foot of the pendulum skidding on the surface to be measured. The skid resistance indicated can be approximately related to coefficient of friction by ... [Pg.224]

The values shown in the table indicate that the material compacts to the desired level with a 5-ton vibrating compactor. Surface skid resistance of the sections was measured using a California portable skid tester in accordance with California test method 342 D. The skid values are comparable with published values for fresh-open or dense-graded asphaltic concretes. The friction values increased with increasing sulfur concentration. [Pg.163]

Apart from the abovementioned devices, there are also the following skid resistance measuring devices the Japanese Skid Tester (locked wheel type operating speed during measurements, 30-90 km/h), DBV of NASA (locked wheel type operating speed, usually 65 km/h), Komatsu Skid Tester (Japan) (fixed slip ratio type between 10% and 30% slip ratio, operating speed between 30 and 60 km/h) and SRT-3 (Japan) (locked wheel type operating speed between 30 and 90 km/h). More information is provided in NCHRP (2000). [Pg.719]

The ASTM locked wheel skid tester or the pavement friction tester (PFT) was developed in America and is one of the first pavement surface skid resistance measuring devices. [Pg.726]

The continuous reading, fixed slip technique is similar to the abovementioned locked wheel skid tester technique but it provides a record of skid resistance along the whole length of the test track surface. It also enables averages to be obtained for specified test segments. Hence, the instantaneous friction reading is recorded and the BFC for each friction length is calculated and recorded. [Pg.727]

Other devices to be mentioned are the Mu-meter (United Kingdom) (fixed slip ratio type 13% or 7.5% operating speed between 20 and 80 km/h) and the Runway Friction Tester (United States) (fixed slip ratio type 15% operating speed between 30 and 91 km/h). These devices have initially been developed for runway skid resistance measurements. [Pg.719]

The Mu-meter is a trailer towed by a vehicle. The tester measures the side force friction of pavement. The results are expressed as Mu numbers. Skid resistance of paved surfaces is measured by a tester developed by North Carolina State University. This tester is a pendulum tester using a smooth rubber tire. The friction between the tire and the specimen is measured from the energy lost in the pendulum. A standard specification for a smooth tire is covered in a separate standard. ... [Pg.44]
