Wheel Tracker Large Device
Cooper Research Technology
Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. In this machine, two 500x180mm specimens are tested simultaneously by tracking with wheels fitted with pneumatic tyres under specified conditions of load, speed and temperature while the development of the rut profile is monitored at specified intervals during the test. The moulded specimens are inserted and removed from the wheel tracker using an Easy-load system.
The Wheel Tracker Large Device CRT-WTENLD supersedes the French Pavement Rutting Tester by using a unique instrumented measurement device, linked to the data acquisition, to measure the development of rutting during testing. It allows extreme efficiency compared to any other type of devices of its type. The test procedure and conditions are controlled and data acquired using Windows™ software running on a host computer via a high speed digital interface and signal conditioning system.
