4、ut aircrafts overshot the runway when taking off and landing often occur, most ofthem are due to the low friction coefficient of the airport runway. In view of that, measuring thefriction coefficient of runway has being

5、become more and more important. It can guarantee theefficiency of aircraft operations and the safety of people's lives and property.The friction coefficient test vehicle for airport runway is special measuring equipm

6、ent formeasuring the airport runway friction coefficient. From its measure data, we can know whetherthe runway is suitable for safe takeoff and landing of aircraft, and whether the runway needs tomaintain. Up to now, Chi
