Practical Method for Locked-Wheel and CFME Friction Measurement Interconversion
… some advantages compared to the traditional Locked Wheel Trailer (LWST) that also generate the need to compare historical data to the collected with the new device. This thesis is proposing an interconversion method between the measurements from a CFME as the SCRIM and the LWST.

Evaluation Of Pavement Surface Friction Seasonal Variations
… year and a half. Friction was measured using two locked-wheel trailers and a Dynamic Friction Tester. Measurements with the two types of equipment were conducted in the same day. Macrotexture measurements were taken using a Circular Texture Meter on the same locations used for the DFTester …

Reducing Highway Crashes with Network-Level Continuous Friction Measurements
… to measure network-level friction: ASTM E 274 locked-wheel, ASTM E 2340 fixed-slip technique, ASTM E 1859 variable-slip technique, and sideways-force coefficient (SFC) technique. The fixed-slip, variable-slip, and SFC techniques are used in continuous friction measurement equipment (CFME). In …

Quantifying the Relationship Between Skid Resistance and Wet Weather Accidents for Virginia Data
… between wet skid resistance measured with a locked-wheel trailer using a smooth tire and wet accident rates is examined. Additionally, the influence of traffic volumes on accident rates is considered. The research used accident and skid data from the Virginia wet accident reduction program as …

Comparison of Surface Characteristics of Hot-Mix Asphalt Pavement Surfaces at the Virginia Smart Road
… for both friction and texture properties. A locked wheel skid trailer and a laser profilometer were used to assess the pavement surface characteristics. Laboratory testing of the pavement wearing surface mixtures was performed to determine volumetric and mixture specific characteristics. …

Experimental and Modeling of Pneumatic Tire Performance on Ice
… influence of braking operations including the locked wheel condition. Experimental studies, carried out at the Terramechanics, Multibody, and Vehicle Systems (TMVS) Laboratory, were performed on the Terramechanics Rig. The investigation included measuring the bulk temperature distribution at …

Evaluation of Continuous Friction Measuring Equipment (CFME) for Supporting Pavement Friction Management Programs
… used around the world for measuring friction. Locked-wheel skid trailers are the predominant technology for roadways in the U.S. However, Continues Friction Measuring Equipment (CFME) is emerging as a practical alternative, especially for network-level monitoring. This type of technology has …
