Asphalt is an increasingly popular choice for paving commercial parking lots due to its durability, affordability and environmental friendliness.
Though asphalt may appear impervious, it does require regular maintenance and repairs over time. These fixes should be performed to keep your property looking great and extend the pavement’s lifespan.
Asphalt
Commercial paving is an integral component of any property’s infrastructure, providing the surface for driving lanes, walkways and parking lots. When done correctly, successful adelaide paving projects can offer businesses numerous advantages.
Asphalt is a popular option for commercial paving due to its durability and cost-efficiency. With proper care, this material can last for many decades.
Ecologically friendly, up to 99 percent of asphalt can be recycled for future projects. Furthermore, porous asphalt allows water to drain away from the surface and back into the ground beneath it.
Are you in need of a fresh new look or simply need maintenance on your commercial property? Paving services can give your commercial property an eye-catching appearance that attracts customers and increases the value of your business. However, be sure to select a reputable company who will guarantee that each job is done correctly the first time around.
Before your paving contractors can lay an asphalt surface, they must grade the area and prepare it for installation. This involves clearing away any existing material as well as reshaping the surface to create a slope for water drainage.
Once the base has been prepared and your property’s structure inspected, your paving contractor can begin laying asphalt. This usually involves using machines with large blades that create a smooth surface for pouring on the material.
Once the asphalt has been laid, your paving company may apply sealcoat to shield it from UV rays, moisture and chemicals caused by vehicles driving over it. Doing this helps prevent your pavement from deteriorating and creating serious issues in the future.
Cracking is a frequent occurrence in commercial paving due to various causes. One of the most prevalent is alligator cracking, which occurs when there’s an inadequate bond between the pavement and subbase. Another cause is edge cracking that often appears near pavement edges.
Concrete
Concrete is a popular commercial paving choice due to its durability and low upkeep needs. Furthermore, it’s more environmentally friendly than asphalt which may contain petroleum byproducts.
Sand, gravel and other small rocks adhered to portland cement create this durable surface that can withstand high traffic volumes as well as adverse weather conditions.
Concrete has more strength and flexibility than asphalt, which tends to be more malleable. As such, it makes an ideal choice for heavy vehicles and other large equipment as well as pedestrians and cyclists alike.
Concrete’s wide distribution of weight allows it to distribute pressure more evenly, while its rigidity prevents cracks in the pavement. Although more costly than asphalt, concrete offers superior durability and long-term cost savings in the long run.
Another advantage of concrete construction is its resistance to frost heaves and expansion/contraction caused by freezing/thawing cycles in wintertime. Asphalt pavements, especially where salt is used for melting snow and ice on roads, often suffer from this issue. In some jurisdictions, laws have been put in place which restrict truck weight during spring thaw season in order to safeguard roadways from such damages.
If your concrete pavement is damaged, a professional paving company can quickly and cost-effectively repair it. They’ll lift the broken pavers, replace them with new ones, and compact the surface back together again for an affordable and timely fix.
You can install concrete paving with a permeable material that allows water to seep through the slab, providing better drainage and decreasing your risk of flooding.
Selecting the correct commercial paving material for your business is critical to its aesthetic appeal and overall quality. If you are uncertain which option would work best in your building, consult an experienced commercial paving contractor about each material’s advantages and drawbacks.
Good paving can make your commercial building stand out from its peers. It attracts more customers and makes the experience more pleasant for your patrons. Furthermore, it increases your property value, potentially leading to higher rents. Finally, good paving saves money on maintenance expenses by reducing the need for multiple repavings or seal-coatings over time.
Permeable
Permeable commercial paving is an eco-friendly technique that prevents stormwater runoff and offers numerous environmental advantages. Unlike asphalt, which traps and retains water on the surface, permeable paving allows rainwater to seep into soil naturally and filter out pollutants before reaching storm drains or retention ponds.
When installing permeable pavement, several factors should be taken into consideration: surface area and soil type. Generally speaking, hydrologic soil group (HSG) A or B soils are preferred.
When selecting a permeable pavement surface for water management and erosion control purposes, the most commonly used options are pervious concrete, porous asphalt and permeable interlocking concrete pavers. Other viable options include plastic grids or amended soils.
Paving surfaces may appear similar to their impervious counterparts, but they feature larger “pores” that allow water to pass through and into the soil. This process is more efficient at retaining water, thus decreasing flooding and erosion risks.
Permeable pavement can also help cool urban runoff, relieving stress on streams and lakes. This is particularly advantageous in densely-populated areas.
Additionally, permeable paving can significantly reduce the need for de-icing salts during wintertime. In some places, the amount of road salt necessary to prevent snow from sticking to asphalt may be reduced by as much as 25%.
Another advantage of permeable pavement is that it can be installed over any type of soil, though HSG A or B soils are preferred as they better meet water management and erosion control objectives.
Installing permeable paving is not a DIY project and should be left to an experienced contractor. They will take into account factors like landscaping, soil type and drainage when designing the surface for best performance.
Installing permeable paving systems can be both visually pleasing and provide numerous advantages. They’re suitable for parking lots, driveways, walkways – with the potential of becoming a green, environmentally friendly alternative to traditional concrete or asphalt surfaces.
Recycled Materials
Recycled materials are used in commercial paving projects to save money, reduce waste, and promote sustainability. These recycled products are commonly referred to as green paving. Not only do they create energy-saving roads, increase safety levels, enhance durability and longevity of surfaces, but they can also increase production productivity through various benefits.
Reclaimed asphalt pavement (RAP) is the most prevalent recycled material used in commercial paving. This highly recyclable material can be reused multiple times, saving money and cutting down on the need for new oil to produce asphalt.
RAP also has a smaller carbon footprint than virgin asphalt, making it an environmentally friendly choice for commercial paving projects. According to NAPA statistics from 2011, RAP usage increased to 66.7 million tons – an increase of 7 percent from 2010.
Ground tire rubber (GTR) is an increasingly sought-after type of recycled asphalt. It can be utilized in either a dry or wet process to replace some of the aggregate in an asphalt mixture and, according to NAPA estimates in 2016, about 1.5 million tons were made up from GTR-containing mixtures.
Steel slag aggregate (SSA) and recycled concrete aggregate (RCA) have been studied as partial or total substitutes for natural aggregates in asphalt mixtures used on road pavements. While SSA and RCA can significantly improve mixture performance, they generally lack certain advantages when compared with natural aggregates.
Incorporating small amounts of SSA or RCA into an asphalt mixture can have beneficial effects on its mechanical and thermal properties. Furthermore, adding a large quantity of these materials can significantly boost stiffness and reduce cracking under cyclic loads.
Comparing to natural aggregates, both SSA and RCA possess higher bulk specific gravity as well as a porous surface that allows them to interact with bitumen and crumb rubber. This reverses the energy flow within the mixture, leading to improved stiffness and fatigue resistance.
Furthermore, adding small amounts of recycled concrete and slag into an asphalt mix has some environmental advantages, such as reduced greenhouse gas emissions and less use of virgin aggregate. However, these aggregates tend to have lower quality than other natural aggregates and may need treatment before being utilized in asphalt mixes for road pavements.
