Pavement Friction Management (PFM) - A Step Toward Zero Fatalities
… is important for highway agencies to monitor the pavement friction periodically and systematically to support their safety management programs. The collected data can help implement preservation policies that improve the safety of the roadway network and decrease the number of skidding-related …

Evaluation of Continuous Friction Measuring Equipment (CFME) for Supporting Pavement Friction Management Programs
It is the responsibility of pavement engineers to design pavements that provide safe and smooth riding surfaces over their entire life cycle. Each year many people around the world lose their lives in vehicle crashes, which are one of the leading causes of death in the United States (US). One of …

The Effect of Pavement Temperature on Frictional Properties of Pavement Surfaces at the Virginia Smart Road
Wet-pavement friction is a public concern because of its direct relation to highway safety. Both short- and long-term seasonal variations have been observed in friction measurements. These variations have been attributed to different factors, such as traffic, rainfall, and temperature. Since both …

Evaluation Of Pavement Surface Friction Seasonal Variations
Wet-pavement friction is one of the most important pavement characteristics in relation to highway safety. This property is difficult to measure because it is affected by many vehicle, driver, pavement, and environmental parameters. In particular, it has been observed that both short- and long-term …

Practical Method for Locked-Wheel and CFME Friction Measurement Interconversion
Pavement friction have become a characteristic of interest due to its impact on road safety. The demand of the transportation agencies for equipment to measure the friction of their pavements grew. Different companies developed in parallel way different devices to satisfy that demand. This generate …

The Application of Intelligent Tires and Model Base Estimation Algorithms in Tire-road Contact Characterization
… of drivers knowledge about the abrupt changes in pavement friction and poor performance of the vehicle stability, traction and ABS controllers on the low friction surfaces are the most important factors affecting car crashes. Due to its direct relation to vehicle stability, accurate estimation of …

Reducing Highway Crashes with Network-Level Continuous Friction Measurements
… the contacting surfaces of the tire and the pavement form frictional forces. The pavement's contribution to tire-pavement friction is referred to as skid resistance and is provided by pavement microtexture and macrotexture. The amount of skid resistance depreciates over time due to the …
