What is the cheapest material for a road base?
Road base is critical for highways, streets and roads that are only effective if they are durable. This article will discuss five of the cheapest materials for road base (asphalt, bituminous pavement, concrete curbs, crushed stone aggregate or slag) along with waste management solutions.
Asphalt is a mixture of aggregates (usually gravel), binder (bitumen) and filler (crushed stones). It’s incredibly stable in both wet and dry conditions which makes it great for road construction. However, asphalt can’t be used on its own because it becomes too soft when hot which causes rutting in the surface of the road. Crushed stone aggregate also has to be used as a base course for asphalt to ensure a long life for the road. If there are cracks or pot holes in the road or driveway, there are pothole filling services that can help repair these damages.
Bituminous pavement is made up of a mixture of bitumen and crushed stone aggregate. It’s also incredibly durable and can be used in wet or dry conditions. However, it can be expensive to install, so it’s not often used as a standalone material. But if you opt for this option, you may want to hire Lincoln, RI pavement services for professional help.
Concrete curbs are made from concrete that is reinforced with steel bars. They are incredibly strong and durable, but they are also quite heavy which makes them difficult to transport. Hence, you may contact concrete delivery services to have concrete delivered directly to your site. Concrete curbs are usually used in conjunction with other materials like asphalt or bituminous pavement.
Crushed stone aggregate is made up of crushed rocks that have been combined with a binding agent. It’s one of the cheapest materials for road base because it can be used in hot or cold weather conditions along with wet, dry and even snowy environments.
Slag is made up of left-over rock from metal smelting plants that contain high portions of iron ore. It’s also one of the cheapest materials for road base because it has a high compressive strength which means it can withstand heavy traffic. Slag doesn’t hold water like other binders which makes it especially useful in times of heavy rainfall when potholes are likely to form.
Choosing the cheapest material for road base is critical for maintaining a durable roadway. Asphalt, bituminous pavement, concrete curbs, crushed stone aggregate and slag are all viable options that come with their own set of benefits and drawbacks. It’s important to consider the environment, traffic and weather conditions when making a decision about which material to use. Waste management solutions are also an important consideration and should be given equal weight when making a decision about road construction.
