Product Information

So you’re not caught out by frost on the ground, it may be worth moving your repair job to later in the day when the temperature is slightly warmer.

Another method is to add a cutting agent, such as kerosene, to make the material easier to work with.

Now let's look at the two main types of cold mix bitumen based surfacing materials in more detail to highlight their intended uses, unique benefits and known limits.

Before we answer this, though, let's get one thing straight; 'cold-lay tar' or 'cold lay asphalt' is a historic terminology used in the surfacing industry for most types of cold mix bitumen based surfacing materials, often used for pothole repair, which are generally supplied in 25kg bags or buckets and sometimes even loose bulk loads. But I'm loath to cut down into the relatively thin tar of the bellmouth, as I think it will leave a small and weakened strip on the downhill side. For repairs to roads or car parks, we would recommend using ULTIPATCH POTHOLE our BBA HAPAS accredited cold-lay asphalt for fast, permanent road repairs. Most cold-lay materials, like the range from Instarmac, do not contain any ingredients that will freeze. As a ready-mixed macadam, Enviro Mastic can be heated using a mastic mixer and applied as a hot-lay formula.As a water-activated formula, Tough Patch can be applied in the rain (just add less water before compaction! Another option for repairing defects, potholes and reinstatements are Permanent Cold-lay Surfacing Materials (PCSMs) which have become more popular in recent years, as they are designed for permanent repair and are approved by the Highways Authority Product Approval Scheme, known as HAPAS in the industry. The good news is it’s very likely there is nothing wrong with the formula itself if the bagged asphalt is still within its expiry date.
