25KG Colmac Cold Tar Ready to Use Direct from Bag - Asphalt, Pothole, Driveway Instant Repair Tarmac

Product Information

You’re likely to come across this problem when the bags have been exposed to cold winter temperatures. Pothole filler is ideal for repairing driveways, roads, car parks, and footpaths where holes can be damaging to car, motorcycle and bicycle tyres as well as a risky trip hazard for pedestrians.

If you are still concerned about bagged asphalt hardening, choose a formula with improved workability. Highly skid and rut resistant, Tough Patch offers a high level of polished stone value (PSV) making it the ideal choice for repairing potholes in heavily trafficked areas or on junctions and turning circles.Sticking down something on top could work, depending on the bond to the existing tar- I wonder if some of the plastic/rubber speedbumps would let too much water through underneath? In such situations, the installer would be required to cut back the edges of the patch to defect-free surrounding surface and properly seal the edges before laying the DSM. ColMac is a 25 kg Cold Tar Tarmacadam product used for repair of Driveways, Potholes, Road Crossings etc.

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.If a tub of cold-lay mix has hardened while in storage, simply remove the mix from the packaging and apply gentle pressure using your knee.

Most permanent cold-lay materials are designed to provide higher placement adhesion than traditional materials and, in some cases, will last a reasonable length of time if well compacted into wet potholes without edge cutback and sealing, or even in shallow defects with minimal preparation.

They are designed to be easy to use and economical, as well as provide durable, lasting repairs and help prevent the ingress of water. But to be on the safe side, Dave advises not to fix potholes when the temperature is close to freezing. The time taken by the Cold Lay Macadam to harden fully will depend on the degree of compaction and ambient temperature.

Obviously as this is at the start of the driveway, it's only ever going to be driven over at about 5mph, but my gut feeling is that concrete laid on tar will crack under a heavy load. They put a 6m long ridge of asphalt about 100mm wide and 50mm high on top of the edge of the road surface. PCSMs tend to have a poor reputation for early failure, mainly due to incorrect installation and sometimes due to user expectations beyond the realistic limits of the material. Road planings need to cool before being repurposed, but can then become a hardwearing and stable surface for hardstandings such as car parks, footpaths, haul roads, farm tracks and yards. The key for these repairs is to apply almost excessive mechanical compaction, avoiding migration of the binder to the surface or crushing the aggregate.
