The spelling of the word "Metalling" can be explained using the International Phonetic Alphabet (IPA) transcription. This word is pronounced as /ˈmɛtəlɪŋ/ and means the process of building or repairing a road with metal. The word is derived from the noun "metal" and the suffix "-ing" which indicates a continuous action. However, it is important to note that this spelling is not commonly used today as the word is now spelled as "metaling" without the double letter "l".
Metalling refers to the process of covering or surfacing a road or pathway with a layer of metal or a metal-based material, typically in the form of loose stones or crushed stone aggregate, to improve its durability, stability, and overall quality. This practice dates back to ancient times when metals such as iron or steel were laid over roads to enhance their resilience.
Modern metalling involves preparing the road base by compacting and leveling it, and then spreading a layer of metal aggregate evenly. This layer typically consists of coarse stones, gravel, or crushed rock of varying sizes, which are then compacted through rolling to ensure a solid and stable surface. Metalling is commonly used in areas with heavy traffic, rural regions, or industrial sites where the natural soil or existing road surface is insufficiently robust to withstand the wear and tear induced by vehicular movement.
The incorporation of metals into roads serves multiple purposes. The metal layer adds strength to the road, preventing the formation of potholes and reducing the erosion caused by weather elements such as rain, snow, or ice. It also improves the road's load-bearing capacity, ensuring it can accommodate heavy vehicles without significant damage. Moreover, metalling enhances the road's lifespan by reducing maintenance requirements, minimizing the need for frequent repairs or resurfacing.
In summary, metalling is the process of surfacing a road with a layer of metal aggregate to enhance its strength, stability, and longevity while minimizing maintenance needs.
The act of forming the surface of a road with broken stones.

The word "metalling" comes from the noun "metal", which has its roots in Latin. The Latin word "metallum" originally meant both "mine" and "metal", derived from the Greek word "metallon" meaning "a mine, a quarry, or a metal". Over time, "metallum" came to exclusively refer to metal, and it was later borrowed into Old English as "metala", signifying "metal". "Metalling" is the present participle form of the verb "to metal", which means to cover a road or path with a layer of crushed stones or gravel, typically made of a mixture of various metallic substances. The term "metalling" related to road construction originated in the early 19th century and likely evolved from the association with crushed stones used in road surfaces that contained metallic elements.
