In the world of construction and landscaping, there are many different types of gravel that serve different purposes. Two of these types are 53 vs 73 gravel, also known as Type 53 and Type 73 gravel –both of which are commonly used in construction. If you’re considering either type of gravel for your next project, it’s important to have an understanding of each kind and how they differ from one another.
First, let’s look at what exactly 53 and 73 gravel are. Both types of gravel are made from crushed rock such as sandstone, limestone, or granite. These rocks are then put through a process that involves crushing them into small pieces and mixing them with a binding agent such as clay or asphalt. The resulting product is gravel of various sizes.
Type 53 gravel is a coarse material commonly used for base layers for roads, driveways, and football fields. The gravel is usually about 0.2 inches (5 mm) in diameter and can range from 1 to 1.5 inches (25 to 40 mm) in diameter. It is easy to spread and grade, making it ideal for soil stabilization and controlling erosion. This type of gravel is composed of stones that are much larger than 73 gravel, resulting in a variety of colors, sizes, and shapes.
On the other hand, Type 73 gravel is a finer material than Type 53 and is primarily used in paving walkways, driveways, and roads. The gravel has a diameter of 0.09 to 0.19 inches (2 mm to 5 mm) and is made up of smaller stones than Type 53. It is generally a whitish-gray in color, though there can be some variation. The smooth stones in type 73 gravel create a non-abrasive compaction that is mostly dust and is ideal for walkways and gardens.
When it comes to choosing between 53 and 73 gravel, there are several factors to consider. Both 53 and 73 gravel are widely available, but 53 gravel often costs just a bit more. 53 gravel is generally easier to work with and can be a bit more forgiving when it comes to mistakes. However, 73 gravel provides a smoother surface when used for paving, walkways, and driveways.
When it comes to durability, Type 53 gravel holds up better in harsh weather conditions, while Type 73 gravel is not as durable. Both 53 and 73 gravel will last and perform best if they are placed onto a stable base and maintained properly with regular weeding and correcting of any traits that have been affected by weathering and erosion.
Ultimately, the type of gravel you choose should come down to the purpose of your project. If you are looking for a long-lasting and durable base layer, Type 53 gravel is the best choice. If achieving a smooth, non-abrasive surface is a priority, then Type 73 gravel is what you’ll want to use. To be sure you’re getting a quality product, always buy from a reliable and experienced gravel supplier.
