Pothole & Trench reinstatement
We produce a specially designed polymer bituminous emulsion mixture in COLAS, which is used for the manufacture of delayed-set macadam (Pothole Patch).
Pothole Patch is ideally suited for all road maintenance work such as pothole repair, trench re-instatement, re-filling core-holes and levelling depressions. It’s also ideal for lightly trafficked areas.
• Pothole Patch manufactured using a COLAS Contracting Cold Mix plant where un-heated aggregate is added directly to the cold
mix plant and coated with pothole patch emulsion.
• This process greatly reduces greenhouse gas emissions as the aggregate is not heated as with a typical hot mix.
• The emulsion is also applied at lower temperatures, between 50 and 60% less heat is required when compared to heating bitumen.
The aggregate grading by COLAS Contracting is with a 2/6mm Gc 85/20 coarse aggregate as specified in Table 2 of IS EN 13043 aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas.
