Oil spills and other surface contaminants
Posted: Wed Apr 26, 2017 11:46 am
Q:(email) Are there any research papers or studies of the coefficient of friction of car rubber tires on asphalt road surface with an oil spill? What are typical values of the coefficient of friction on wet (it just started
raining) road with an oil patch? Is there a difference when oil is mixed with water on the road?
A: Here is a report which address the issue

2009 : Number E-C134
1984: HS-038 006

SURFACE CONTAMINANTS, CHAPTER 7
- Transportation Research Board, A State-of-the-Art Report: The Influence of Roadway Surface Discontinuities on Safety.
This chapter reviews research on how various surface contaminants can adversely affect highway safety, mainly through a very drastic reduction in traction, and the steps drivers can take to allow for this. The bulk of the chapter is concerned with ice and snow which provides the most hostile and least-forgiving environment a driver is likely to encounter. Even with the best traction aids, such as studded tires, snow tires and chains, the total traction available to propel and stop a vehicle and perform turning maneuvers is much less than even a relatively poor quality rain-slick highway. The chapter also touches on the reduced traction caused by mud and spilled diesel fuel. The latter is a rare occurrence. However, its very hazardous nature (coefficients of friction as low as that of wet ice) cause it to be noted here.
