Factors That Affect Asphalt Paving Costs
Asphalt is an eco-friendly material, helping keep both people and goods moving smoothly. Recyclable materials make asphalt even more advantageous as a sustainable choice that can be recycled over time. Best way to find the Asphalt companies Long Beach.
Asphalt mixtures are comprised of aggregates, binder, and filler ingredients combined in order to meet specific application needs. Different applications may call for different mixes; highways require high-performance mixes capable of withstanding heavy traffic loads, while residential driveways may prefer using lighter mixes.
Cost of Materials
Materials cost is one of the primary determinants in paving costs, as asphalt is a petroleum-based product and, therefore, fluctuates with oil market fluctuations. Professional paving contractors understand how to balance cost-effectiveness with quality in order to produce long-lasting and durable results.
Your choice of asphalt will also impact material costs. Standard hot mix asphalt typically ranges between $100 and $200 a ton; recycled or reclaimed asphalt tends to be cheaper but typically only lasts one season; colored blacktop can range between $12 and $17 per square foot when using pigmented hot mix asphalt as a base.
Porous asphalt contains tiny pores that allow water to filter through and seep into the ground below, creating an ideal option for large parking lots where runoff or depletion of groundwater may occur. Porous pavement also adds curb appeal while remaining as strong as traditional pavement.
Before any paving occurs, professionals must excavate and grade the area for a flat surface resistant to erosion. This process may become particularly expensive in the regions that slope, have poor drainage, or require excavation for other reasons (if drainage systems are mismanaged, pavement can sink or crack over time). When planning an excavation project, be sure to obtain quotes from multiple paving companies for their estimate on excavation.
Cost of Labor
Labor costs in asphalt paving projects can vary depending on their size and scope, site preparation needs, and condition of existing pavement (i.e., if your driveway slopes significantly or requires significant leveling and grading work, your labor costs will likely be higher) as well as what was planned out initially for an entirely new installation.
Asphalt production requires heating ingredients to a high temperature and maintaining this temperature during construction, hence why most asphalt is produced at an asphalt plant instead of on-site. Furthermore, an asphalt plant offers various chambers dedicated to different recipes and is equipped to adjust mixes according to climate, traffic volume, and noise reduction needs.
Once a mix is prepared, it is transported via dump trucks to a construction site and applied using specialized paving equipment before being compacted using heavy rollers – this ensures no voids remain and structural integrity is protected. Compaction also plays an essential role in prolonging asphalt’s longevity by helping avoid future issues like rutting and cracking.
Environmental and safety considerations also can affect asphalt pricing. For instance, porous asphalt allows oxygen and water vapor to pass through, benefitting both the environment and drainage processes naturally. Furthermore, porous asphalt melts ice quicker than concrete pavement, which makes pedestrians safer in severe weather.
Cost of Equipment
Equipment used in asphalt paving projects is an essential factor in its cost, such as milling machines or graders for material removal, pavers, and compactors – the price of which varies depending on project size and scope; moreover, job size dictates how much material needed to be covered over an area which impacts labor costs as well.
Gravel is often the least expensive material to choose, yet it lacks durability in heavy rainstorms and can become slippery and muddy when wet, while concrete requires less upkeep than gravel and can last much longer with proper care and maintenance. Porous asphalt offers another cost-cutting alternative as an EPA best practice in drainage; its small holes allow water to pass through instead of collecting on its surface, preventing flooding or erosion from happening.
An important consideration during asphalt installation is the temperature of the mix itself. Optimally, it should be hot enough to enable proper compaction without cooling before being rolled and laid, and this ensures it binds tightly with existing soil while supporting heavy vehicles such as cars or trucks. Furthermore, using asphalt at an ideal temperature saves money through decreased energy use and reduced fume emissions.
Cost of Site Preparation
Asphalt paving materials are highly sought-after due to their durability and strength, as well as aesthetic options, including being colored to add flair. While concrete may also be an option, its upkeep requires additional costs due to requiring chemical sealants, which increase overall costs.
Asphalt creation starts with mixing aggregates and bitumen in an asphalt mixer, such as crushed rock, sand, gravel, or recycled materials; bitumen is typically the chosen binder, but bio-based binder technologies may soon emerge to reduce environmental impacts associated with asphalt.
After mixing, asphalt mix is heated and dried at an asphalt mixing plant before being delivered to construction sites for spreading and compacting with special paving equipment. Compaction is critical in minimizing rutting or other pavement failures that could arise as part of this process.
Before laying asphalt, an 8-10 inch layer of gravel must first be spread across the ground to provide stability and prevent future damage, increasing costs by $1-$2.50 per square foot for this step alone. In addition, this foundation layer is coated with an oil-based binder to hold down any shifting gravel deposits.
