The pre-bituminised S&P asphalt reinforcement grids, Carbophalt^® and Glasphalt^®, are made of carbon and/or glass fibres. They are effective in significantly reducing the build up of cracks and help to prevent crack reflection from the layers below. As well as crack prevention, they increase the load bearing capacity of the substrate therefore ensuring the surface layer is much more durable. The S&P asphalt reinforcement grids are easy to install and offer a cost-effective method of quickly repairing asphalt surfaces. They are both easily millable and recyclable. The pre-bituminisation guarantees the regulated bond strength between the asphalt layers.
