WEARING COURSE Meaning and
Definition
-
A wearing course, in the realm of construction and engineering, refers to the topmost layer of a road or pavement that is specifically designed to endure the daily wear and tear resulting from constant vehicular traffic. Also referred to as the wearing surface or wearing layer, it serves as a protective shield for the underlying layers, prolonging the road's lifespan and maintaining its functional and aesthetic qualities.
Typically composed of durable materials such as asphalt concrete or a bituminous mixture, the wearing course exhibits exceptional resistance to abrasion, skidding, and weathering. Its thickness varies depending on the traffic volume and the road's location; high-traffic areas usually require a thicker wearing course to withstand the heightened stress placed upon the roadway.
The wearing course plays a critical role in providing a smooth and safe traveling surface for vehicles, enhancing road visibility during adverse weather conditions, and reducing noise levels. It ensures the uniformity of the road surface, preventing water infiltration into the lower layers, and improving the overall stability of the pavement. Additionally, it can incorporate certain additives or aggregates to enhance its properties, such as increasing friction to prevent skidding or integrating reflective materials for better visibility at night.
In conclusion, the wearing course is an essential component of road construction, providing resilience and longevity to the road surface while ensuring the safety and comfort of motorists.

Etymology of WEARING COURSE
The etymology of the term "wearing course" can be broken down as follows:
1. Wearing: The word "wearing" comes from the Old English word "werian", which means "to carry, have on one's person". It is also related to the Old High German word "werian" and the Gothic word "weisan", both carrying similar meanings.
2. Course: The term "course" has a Latin origin. It comes from the Latin word "cursus", which means "a running, a race, a course". It is derived from the verb "currere", meaning "to run".
Therefore, when combined, "wearing course" refers to a layer or surface of a road or pavement that is designed to withstand the effects of regular wear and tear caused by vehicle traffic. It is the part of the road that comes in direct contact with the vehicles as they travel on it.
