In the UK, tarmac is a commonly used material for driveways, roads, pathways, car parks, and play areas. It is made up of a combination of aggregate (crushed rock or sand) and bitumen, derived from crude oil. The different grades of bitumen are classified based on their stiffness and softening temperatures.
Commonly used bitumen grades in the UK include 40/60 pen, 70/100 pen, 100/150 pen, and 160/220 pen. The preferred grade for most applications is 100/150 pen, but 40/60 pen is used for heavily trafficked roads, and 160/220 pen is often used for hand lay work as it is easier to apply. It is important to choose the right grade of tarmac based on the specific application to ensure optimal performance.

Benefits of Open-Graded Tarmac
Open-graded tarmac, also known as open-graded aggregate, offers several advantages for driveways and other paved surfaces. One of the key benefits is its permeability, allowing water to drain through the surface.
This helps to prevent pooling and water damage, making open-graded tarmac an ideal choice for areas where water drainage is important.
By allowing water to pass through, open-graded tarmac reduces the risk of surface runoff and contributes to sustainable drainage systems.
This permeability also helps to prevent the formation of ice during winter months, as the water can drain away instead of freezing on the surface. This makes it safer for both pedestrians and vehicles.

In addition to its water drainage capabilities, open-graded tarmac is known for its durability. The mixture of larger aggregates in the surface provides increased strength and longevity, reducing the need for frequent repairs or maintenance. This makes it a cost-effective option in the long run.

Benefits of Close-Graded Tarmac

Close-graded tarmac, also known as close-graded aggregate, is a popular choice for creating a uniform surface that enhances the aesthetics of your driveway.
Its dense composition consists of many small particles, usually three millimeters in size or smaller, resulting in a smooth and visually appealing finish.
One of the key advantages of close-graded tarmac is its ability to effectively manage water runoff.
The less permeable surface allows rainwater to flow off the driveway, preventing water pooling and potential damage.
This is particularly important for areas that experience heavy rainfall, helping to maintain the integrity and longevity of your driveway.
When considering close-graded tarmac for your driveway, it is essential to consult with a professional to ensure proper water drainage. They can provide expert guidance and recommend additional measures, such as the installation of suitable drainage systems, to avoid any potential water-related issues.
Whether you’re looking to enhance the curb appeal of your home or create a smooth and durable driveway, close-graded tarmac offers a range of benefits. Its uniform surface and efficient water runoff management make it an excellent choice for those seeking both practicality and aesthetics in their driveway design.
