Whitetopping is a road surfacing technique that involves the placement of a thin layer of white concrete on top of an existing pavement structure. This process is used to improve the functional and aesthetic qualities of a road or pavement. The new layer of whitetopping enhances the pavement's stiffness and fatigue properties, as well as its surface friction, strength, durability, and water impermeability. This results in a longer-lasting and smoother surface that is easier to maintain and provides a more attractive aesthetic. One of the key advantages of whitetopping is its ability to reduce maintenance costs. The new layer of concrete is more durable and resistant to wear and tear than the original pavement, reducing the need for frequent repairs. Additionally, the use of locally available materials in the construction of whitetopping can significantly reduce the overall cost of the project. Another advantage of whitetopping is its ability to improve the safety of the road or pavement. The new layer of concrete provides better skid resistance, reducing the risk of accidents caused by slippery surfaces. It also improves the visibility of road markings, making it easier for drivers to navigate the road. Whitetopping is a sustainable solution for pavement reconstruction and rehabilitation. It reduces the need for new materials and minimizes the amount of waste generated during the construction process. Additionally, the use of white concrete can help to reduce the urban heat island effect, which is caused by the absorption of heat by dark surfaces.

Whitetopping is a pavement preservation method in which a layer of concrete is laid directly on top of the existing layer of asphalt. This process is often used to extend the life of older roads and to reduce the need for additional repairs in the future. It is considered a cost-effective solution for many municipal governments.
Equivalent terms across other languages for Whitetopping include: French: recouvrement blanc, German: Weiß-Beschichtung, Russian: бeлый покрытие, Spanish: revestimiento blanco, Hindi: सफेद आड़ू, Japanese: ホワイトトッピング, Chinese: 白色涂层, Italian: Rivestimento bi
Whitetopping is a noun. It refers to a concreted area that is laid on a road surface for reinforcement and strengthening. Synonyms for Whitetopping include paving, surfacing and asphalt. An antonym for Whitetopping is asphalt removal. Cognates of Whitetopping include white topping in other languages such as Spanish (blanqueado superior) and French (revêtement blanc). Variants of Whitetopping include whitetop, white-topped, whitetopped and white topping.

Whitetopping, literally translated, implies the covering of an existing surface such as a road, in white material. However, the term has been used in the context of a pavement overlay since the late 1960s, becoming increasingly popular in the early 2000s. The term ‘whitetopping’ as used in pavement reconstruction and/or rehabilitation, is a high-performance thin whitish concrete overlay of between 2.5 and 7.6 cm thick that is placed over an existing pavement or other base material. The concept offers several advantages over conventional asphalt and concrete pavements in terms of reduced maintenance costs, improved safety characteristics, the incorporation of environmental benefits, and the use of locally available materials. Whitetopping has become an innovative, proven and cost-effective solution to pavement reconstruction and rehabilitation and has been widely adopted in countries around the world.
Etymology, Morphology, Whitetopping, Language, Historical Evolution.
Whitetopping is a road surfacing technique that is used to improve the aesthetic and functional qualities of a road or pavement. It is a process where asphalt or concrete is placed on the surface of an existing pavement structure, creating a new layer that is separate from the old one. The new layer of whitetopping improves the pavement's stiffness and fatigue properties, as well as its surface friction, strength, durability and water impermeability. This results in a longer-lasting and smoother surface that can also provide a more attractive aesthetic, as well as being easier to maintain.
