Introduction Plastic running tracks have become increasingly popular in recent years, especially in schools and athletic facilities. These tracks are durable, low maintenance, and provide a safe surface for athletes to run on. However, one important question that often arises is what is the ideal size of the gaps between the plastic track tiles? In this article, we will explore the different factors that affect the size of the gaps in plastic running tracks and discuss the ideal gap size for different types of tracks. Factors that Affect the Size of Gaps in Plastic Running Tracks 1. Climate One of the key factors that affect the size of gaps in plastic running tracks is the climate in which they are installed. In regions with high temperatures and humidity, the gaps between the tiles need to be larger to allow for expansion and contraction. This is because plastic materials tend to expand when exposed to heat and contract when exposed to cold temperatures. Therefore, in areas with a high temperature range, the gaps need to be larger to prevent the tiles from buckling or cracking. 2. Type of Track The size of the gaps between the tiles also depends on the type of plastic running track. There are two main types of tracks: full-pour and sandwich. Full-pour tracks are made of a single layer of plastic material, while sandwich tracks have a base layer of rubber and a top layer of plastic. The size of the gaps in full-pour tracks is typically smaller than in sandwich tracks because they are more flexible and can expand and contract more easily. 3. Type of Plastic Material The size of the gaps in plastic running tracks also depends on the type of plastic material used. There are several types of plastic materials used in running tracks, including polyurethane, EPDM, and SBR. Each of these materials has different properties and requires different gap sizes. For example, polyurethane is more flexible and requires smaller gaps than EPDM and SBR. Ideal Gap Size for Different Types of Tracks 1. Full-Pour Tracks For full-pour tracks, the ideal gap size is between 3mm and 5mm. This size allows for expansion and contraction of the plastic material without causing any damage to the track. However, it is important to note that the gap size may vary depending on the climate and the type of plastic material used. 2. Sandwich Tracks For sandwich tracks, the ideal gap size is between 6mm and 8mm. This size allows for the rubber base layer to expand and contract without affecting the plastic top layer. Again, the gap size may vary depending on the climate and the type of plastic material used. Conclusion In conclusion, the size of the gaps in plastic running tracks is an important factor to consider when installing a new track. The ideal gap size depends on several factors, including the climate, type of track, and type of plastic material used. For full-pour tracks, the ideal gap size is between 3mm and 5mm, while for sandwich tracks, the ideal gap size is between 6mm and 8mm. By taking these factors into consideration, you can ensure that your plastic running track will provide a safe and durable surface for athletes to run on.
