PORTABLE FRICTIONAL RESISTANCE MEASUREMENT TESTER

摘要

PURPOSE: A skid resistance measurement tester is provided to prevent unnecessary measurement errors by a surveyor with a non-gravity digital method. CONSTITUTION: A skid resistance measurement tester comprises a cylindrical rotator(510), a motor(520), a supporting frame(540), and a measurement frame(560). The rotator includes the bottom surface for measuring the skidding of a road. The motor rotates the cylindrical rotator. The supporting frame connects the cylindrical rotator and a rotary shaft of the motor so that the rotary shaft of the motor can rotate the cylindrical rotator.
