Tar and chip roads are a popular choice for many reasons, but their longevity and durability largely depend on the quality of the base. When constructing a new tar and chip road, it is important to consider the type of base material used. This article will explore the benefits of using gravel as the base material for tar and chip roads.
Gravel Base Material
Gravel is a natural aggregate made of various-sized particles, ranging from small stones to larger rocks. It is easily accessible and inexpensive, making it a popular choice for road construction projects. In addition, gravel base has excellent drainage properties, which help prevent water from pooling on the road’s surface and causing damage.
Ground Preparation
Before the gravel is laid down, the ground underneath must be properly prepared. It typically involves removing any topsoil or vegetation and grading the surface to ensure it is level. The ground may also be compacted if necessary to create a stable foundation.
Sub-Base
Once the ground is prepared, the first layer of gravel can be laid down. This layer is usually 4-6 inches thick and is known as the sub-base. The purpose of the sub-base is to provide support and stability for the road’s upper layers. It also helps distribute the weight of vehicles evenly across the road surface, preventing areas of concentrated stress.
Base Course
After the sub-base is in place, the next layer of gravel is added. This layer is typically 2-3 inches thick, known as the base course. The base course provides additional stability and acts as a barrier between the sub-base and the final layer of asphalt.
Tar and Chip Process
With the base course in place, the tar and chip process can begin. First, hot liquid asphalt is applied to the base course. The asphalt acts as a binder, helping hold the gravel together and providing a smooth surface for vehicles to drive. As soon as the asphalt is applied, gravel is spread over the top. This layer of gravel is usually around 1/4 to 3/8 inch in size and is known as the chip seal. The chip seal is pressed into the asphalt while still hot, creating a strong bond between the materials.
Curing Period
Once the chip seal has been applied, the road is left to cure for several days. During this time, the asphalt will harden, and the gravel will settle, creating a stable and durable surface that can withstand heavy traffic.
Benefits of Gravel as a Base Material
Using a new tar and chip road as the base material offers many benefits. Here are five advantages of using gravel as a base material:
Provides support and stability: Gravel provides a stable foundation for the upper layers of the road. It helps distribute the weight of vehicles evenly across the road surface, preventing areas of concentrated stress.
Allows for excellent drainage: Gravel has excellent drainage properties that prevent water from pooling on the road’s surface and causing damage. It helps prolong the lifespan of the road and reduces maintenance costs.
Prevents water damage: In addition to its drainage properties, gravel also acts as a barrier between the sub-base and the final layer of asphalt. It helps prevent water from penetrating the road’s surface, reducing the risk of water damage.
Readily available and cost-effective: Gravel is easily accessible and inexpensive, making it an ideal choice for road construction projects of all sizes.
Environmentally friendly: Gravel is a natural aggregate that does not require additional processing, making it an environmentally friendly option for road construction.
Using gravel as the base material for a new tar and chip road is an excellent choice. It provides the necessary support and stability for the upper layers, allowing for excellent drainage and preventing water damage. Additionally, gravel is readily available and cost-effective, making it an ideal choice for road construction projects.
