Asphalt paving Johannesburg
Asphalt paving Johannesburg is known for its durability and resilience. It is this strength which makes asphalt pavement the best option for most all paved surfaces. Most consumer, municipalities and governments highly prefer this type of pavement because of its reliability and lasting life. If it is properly laid, it need not be replaced for twenty to twenty-five years.
Asphalt pavement is also the most popular choice for applications such as driveways, parking lots, roadways, airstrips and more. Its application exists literally everywhere.
Interestingly, asphalt is also the most commonly recycled material in the western world – even before paper or plastic! Approximately 80% of all Asphalt paving Johannesburg is recycled when it is removed. Without question, if you are looking for lasting pavement for these applications, and one that can be used over and over again, asphalt pavement is the best choice.
Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil.
Asphalt is a sustainable paving solution made from a mixture of aggregates, binder, and filler. Aggregates are processed mineral materials such as crushed rock, sand, gravel, slags, or various recycled materials.
Smooth Asphalt paving Johannesburg reduces the friction between tires and roads, which means better fuel economy and reduced carbon dioxide emissions. Special warm mix asphalt roads can be constructed at lower temperatures, further reducing the energy required to heat asphalt materials for road paving.
Concrete lasts longer, but asphalt driveways are less expensive to install. Asphalt needs more maintenance, but is generally easier to repair
An important fact to remember is that before the asphalt pavement is applied, there is a great deal of preparation that occurs. In fact, unless the asphalt is being laid over existing asphalt (overlay), it is the preparation of the ground beneath the pavement that is the most influential factor in the life of an asphalt pavement surface. Proper clearing, excavation, ground compaction and base materials require a great deal of expertise.
