Describing a material, substance, or construction that does not contain or utilize asphalt. Asphalt is a black, viscous mixture of hydrocarbons derived from petroleum, commonly used as a binding agent in road construction, paving, roofing, and other applications. 'Non-asphaltic' indicates the absence of this specific substance, implying alternative materials or methods are employed in its stead, these often include concrete, gravel or brick paving. This term is relevant in the context of infrastructure, construction, and material science where properties, durability, and environmental impact can differ greatly from those used with asphaltic applications.
Non-asphaltic meaning with examples
- The new city sidewalk project specified the use of non-asphaltic concrete pavers to reduce heat absorption and improve water permeability, aligning with the city's green initiatives. Their installation involved a unique interlocking system that negated the need for asphalt. The selection was based on sustainability and providing a more pleasant pedestrian experience on hot days.
- Researching roofing materials, the building owner opted for a non-asphaltic roofing membrane made from a durable polymer blend. The choice was made to withstand extreme weather conditions and provide a longer lifespan compared to traditional asphalt shingles. This also eliminated issues often associated with asphalt's cracking over time, and its susceptibility to damage.
- Construction of the parking lot called for the use of non-asphaltic permeable pavers, that were a type of gravel set in a porous bed. This decision was made to manage stormwater runoff, prevent flooding, and recharge the groundwater. This environmentally conscious choice provided a aesthetically pleasing alternative to traditional asphalt parking areas.
- During the rehabilitation of the historic district, the city council mandated non-asphaltic materials for all street repairs. The use of brick and cobblestone not only preserved the historical aesthetics, but also offered increased longevity, and resistance to deterioration. Asphalt, although useful in its own right, was considered an aesthetic and possibly environmental negative.
