Have you ever seen a paving contractor spread sand over freshly installed asphalt? It may look strange, but there is a good reason for it. In this post, Scorpion Construction LLC will discuss the benefits of this practice and how it can help improve the lifespan of your asphalt pavement.

Asphalt Surface Formation

Asphalt is a mix of gravel, sand, and bitumen. When it is first installed, the asphalt is in a liquid state. Your paving contractor will use a large machine to spread the asphalt over the ground’s surface. Once the asphalt has been laid, it will begin to cool and harden.

As it cools, the asphalt will start to form a solid surface. However, this surface will be very porous and not very strong. The pores on the surface of the asphalt allow water to seep through. This can lead to serious problems if there is heavy rain or snowfall soon after the asphalt has been installed. The water can cause the pavement to crack and break apart.

Scattering Sand Over Newly Installed Asphalt Surface

The reason that contractors throw sand on newly installed asphalt is multifold.

1. Fills in the Voids in the Asphalt

First, the sand helps to fill voids or gaps in the asphalt. To prevent the new asphalt surface from water damage, paving contractors will often scatter sand over the surface. The sand helps fill the pores and creates a more robust, durable surface. It also provides traction for vehicles, especially in wet or icy conditions.

2. Provides a Protective Barrier

Second, the sand provides a protective barrier between the asphalt and vehicles. The sand also helps to absorb any impact from cars, which can help extend the lifespan of your asphalt pavement.

3. Increases Pavement Durability and Life Expectancy

It helps to increase the durability and life expectancy of the pavement and can prevent costly repairs down the road. So next time you see a paving contractor spreading sand, you’ll know it’s not just for show. It’s an essential part of the asphalt paving process.

4. Better Traction

Dusting sand over newly laid asphalt will significantly increase your car’s traction. It prevents slipping or sliding on wet pavement as the new surface has a better grip.

5. Enhances the Look of the Asphalt Surface

Last but not least, the sand enhances the asphalt surface’s aesthetics. It gives it an excellent, even finish, that is much more visually appealing than plain asphalt.

So, there you have it. The next time you see a paving contractor sanding newly installed asphalt, you’ll know there’s a good reason for it. It’s not just for show – it’s an essential part of the process that helps to ensure a long-lasting, durable pavement.
