TESTING
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, and Pavement porosity.
Transtec’s pavement experts can help measure these pavement properties and assess their contribution toward splash & spray.
How do I construct a pavement with increased macrotexture depth?
Transtec’s pavement experts are knowledgeable in pavement materials and construction methods.
We can create pavement construction specifications optimized for your region to meet improved splash & spray performance and safety levels.
