Microtexture is defined as texture ("bumps and dips") in a pavement with a wavelength (distance from "bump" to "bump") less than .5 mm. Most microtexture in pavements is manifested as texture on the individual stones and/or the finer sand in the asphalt mixture or concrete mortar.

Why is dry pavement creates more friction than ice pavement does?

Dry pavement creates more friction than ice pavement because when surfaces are dry, there is more contact between the tires and the road, leading to increased friction. On the other hand, ice has a low coefficient of friction, causing tires to slip more easily since there is less traction between the ice and the tires.


What results in the formation of desert pavement?

Desert pavement is formed when wind erosion removes finer particles of soil, leaving behind a layer of coarser particles such as sand, gravel, and pebbles. Over time, these larger particles become tightly packed and form a hard, erosion-resistant surface that resembles a natural pavement.


Explain why potholes form in colder regions and not warmer?

Potholes form in colder regions due to the freeze-thaw cycle. When moisture gets into cracks in the pavement and freezes, it expands, stressing the pavement. As temperatures rise and the ice melts, the pavement contracts, leaving gaps that weaken the surface and lead to potholes. In warmer regions, the lack of significant freeze-thaw cycles reduces this pavement stress, resulting in fewer potholes.


How a dry spot on a wet pavement can be used to confirm in forensic?

A dry spot on a wet pavement can indicate that an object or a person was present at that spot when the pavement was wet. This can be useful in forensic investigations by showing the location where an object or person was placed or removed from the scene. It may also suggest tampering or movement of evidence.
