For measuring the lateral force coefficient pavement, airport pavement or cement concrete pavement, the test results can be used as the final acceptance or use of pavement skid resistance assessment is based; and provide a basis for road maintenance.
Applicable Standards：
ASTM E670-09, JTG-E60-2008, JT/T752-2009, JJG100-2010; JT/T778-2010
Product Parameters：
| Test speed | low speed of 20 km / h, high speed up to 100 km / h |
| Operating temperature | -25ºC~ + 60ºC |
| Relative Humidity | ≤100% |
| Friction test tire (particularly smooth type) tire pressure | 70KPa ± 3.5KPa |
| Measuring wheel for wheel tracks with the road surface friction coefficient measurement; and ensure that the test can be stabilized within a speed range; | |
| Friction test accuracy | Test length not less than 15m between the two tests, the average friction coefficient ± 0.01 |
| With tension sensor 0-1000Kg, accuracy <0.05%; | |
| Distance measurement accuracy | ± 0.1% plus tire wear (can be based on the distance to the Station, and may be amended) |
| The ground when the weight of the test wheel (left and right wheels) | 77.56 ± 1kg |
| Trailer connection | spherical hook |
| Has a counterweight rotating the wheel isolation test wheel stabilization mechanism; | |
| Have damaged the road wheel to quickly stabilize the pressure compensating mechanism; | |
| Sprinkler system | the ability to adjust the amount of watering according to the test speed, to ensure relatively constant water film thickness testing |
| Water film thickness | test front wheel sprayed water film thickness of 0.5mm or 1mm error ≤15% |
| Flow rate | The actual flow can be controlled using the variable-speed pump to ensure proper water film thickness |
| Sprinkler System Power | powered by the car itself, no external power supply unit; |
| Data transmission | wireless transmission; |
| Computer Systems | Software support windows2000 / XP / Vista / Windows7 operating system; |
| Machine computer equipment integration and test the next bit, controlled by a laptop PC and operating all the work. | |
