Introduction Plastic running tracks have become increasingly popular in recent years due to their durability, low maintenance, and safety features. However, when it comes to installing a plastic running track, one of the most common questions is how much rubber granules are required for the job. In this article, we will explore the answer to the question, "How much does a 25kg bag of plastic running track granules cover?" What are Plastic Running Track Granules? Plastic running track granules are small, rubber particles that are used to create a cushioned surface for running tracks. These granules are typically made from recycled rubber and are mixed with a binder to create a durable and long-lasting surface. The granules are available in different colors and sizes, allowing for customization of the running track's appearance. Calculating the Coverage of a 25kg Bag of Plastic Running Track Granules The coverage of a 25kg bag of plastic running track granules will depend on the thickness of the layer that is being applied. The recommended thickness for a running track surface is typically between 12-15mm. To calculate the coverage of a 25kg bag of granules, we need to know the surface area of the running track and the thickness of the layer. For example, let's assume that we have a running track that is 100m long and 6m wide. To calculate the surface area, we multiply the length by the width, which gives us 600 square meters. If we want to apply a 12mm layer of granules, we need to convert the thickness to meters, which is 0.012m. To calculate the volume of granules required, we multiply the surface area by the thickness. In this case, the volume of granules required is 7.2 cubic meters (600 x 0.012). To convert this volume to weight, we need to know the density of the granules. The density of plastic running track granules is typically around 700kg/m3. To calculate the weight of granules required, we multiply the volume by the density. In this case, the weight of granules required is 5,040kg (7.2 x 700). As a 25kg bag of granules covers approximately 1 square meter at a thickness of 12mm, we will need 288 bags of granules (7,200 / 25). Conclusion In conclusion, the amount of plastic running track granules required to cover a surface depends on the surface area and the thickness of the layer being applied. A 25kg bag of granules will cover approximately 1 square meter at a thickness of 12mm. Therefore, for a running track that is 100m long and 6m wide with a 12mm layer of granules, we will need approximately 288 bags of granules. It is important to note that the coverage may vary depending on the type of granules used and the installation process.
