Splash and spray is a surface characteristic that directly affects road safety. Generation of both splash and spray begin with the same basic mechanism: as a vehicle drives down a wet road, the water beneath the tire will be displaced. Some of this water will be ejected in bulk – as an airborne wave or jet of water termed splash. Some of the water is more finely divided – a result of high localized pressures, strong air currents, and the dynamics of the tire imparting both rapid vibrations and centrifugal forces. In this case, the water takes the form of a spray.
One particular section of road in my region has an excessive number of complaints and accidents related to reduced visibility during rainy weather. Why?
Surface properties that affect splash & spray include:
- Cross slope
- Macrotexture depth
- Pavement porosity
Transtec’s pavement experts can help measure these pavement properties and assess their contribution toward splash & spray.
