Abstract

The aim of our research was to design and construct a measuring device that can determine the rolling resistance coefficient (RRC) under laboratory conditions. The measuring device has a drum arrangement, and the RRC was measured on two different model surfaces. The deceleration method was used to investigate the dependence of RRC on compression force, velocity, and surface temperature on steel and rubber surfaces. The measured RRC values (0.010 – 0.025) were similar in magnitude to the values characteristic for asphalt-covered roads. By increasing the model road surface temperature up to T = 60 ◦C the RCC dropped by ∼ 13% compared to the values at T = 22 ◦C
