一、Product Introduction

This instrument simulates the frictional effect of vehicle tires on road surfaces in controlled environments. By accelerating the abrasion of aggregate materials used in pavement construction, it measures the abrasion resistance of aggregates. This provides scientific evidence for selecting appropriate surface layer aggregates to meet varying friction coefficient requirements, facilitates the rational development and utilization of stone resources, shortens research cycles for anti-skid pavement development, and offers technical references for creating high-quality artificial aggregates.

二、Technical Parameters

1、Power supply voltage	AC380V 50HZ [Note: Three-phase four-wire]
2、Road rotation speed	320±5 rpm
3、Total pressure of rubber wheel on road wheel test piece	725±10N
4、When the power is turned off during the test, do not turn off the power switch on the controller panel. The number of turns will be stored and displayed again when the power is turned on.
5、When the test is over, turn off the power switch on the panel to save the battery inside the machine.
6、The flow rate can be controlled by adjusting the flow meter
