Wheel Road Surface Pavement Automatic Coefficient of Friction Tester

Product DescriptionWheel Road Surface Friction Coefficient Automatic Test Equipment (Lateral Force)PurposeFor 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. Equipment componentsConnect device and sprinkler;Trailer test equipment;Portable computers;Water film thickness control system;Infrared temperature measurement system.Feature  Test wheel angle: 15 °;Surface water film thickness (0.5 ~ 1mm) control;Test wheel state and the water film thickness video monitoring;Software testing and data processing functions:(1) Display and record the coordinates of the position and velocity, friction coefficient corresponds to the curve, continuous path diagram depicts the entire test section of the friction coefficient and velocity; Determination road class speed can be selected according to the needs.       (2)The Friction coefficient measurements results correspnd with the Station Road, the average output of (You can choose 5 m, 10 m, 20 m, 100 m, 1 km)each friction coefficient,standard deviation, coefficient of variation, friction coefficient statistical number; 20m and above a representative value can be drawn from the given section of the measured maximum and minimum frictional resistance value, SFC value;       (3) it can set relevant initial parameters, including: weather, temperature, humidity, road grade, road conditions, the test name, test date, time and related notes and the like; the parameters set by the user, and notes will be reflected in the report Classification ; continuous or intermittent measurement determined and measured per kilometer length is determined according to use.      (4) Test software can calculate the friction coefficient values of each interval, the travel distance, speed, output reports in Excel format, print out the friction coefficient of the test report;      (5) Software real-time control and monitoring system status, failure to timely alarm;      (6) it has a compensation test vehicle in motion, the next move and uneven pavement joint compensation mechanism (patent products);      (7) configuration friction wheel rotation mechanism driving and self-locking device, according to test it needs from the two rounds of testing parallel transport condition (0 ° angle), conversion to test the state has a certain angle (15 ° angle), the state after the conversion, automatic locking.Product ParametersTest speedlow speed of 20 km / h, high speed up to 100 km / hOperating temperature-25 ºC ~ + 60 ºCRelative Humidity≤100%Friction test tire (particularly smooth type) tire pressure70KPa ± 3.5KPaMeasuring 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 accuracyTest length not less than 15m between the two tests, the average friction coefficient ± 0.01With tension sensor 0-1000Kg, accuracy
