Purpose:
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.
Equipment components
● Connect device and sprinkler;
● trailer test equipment;
● portable computers;
● water film thickness control system;
● infrared temperature measurement system.
2. Equipment features
● 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.
