TSE K 50

TSE K 50 is a withdrawn TSE standard covering cold mix asphalt for repair of asphalt pavement. In practice, this type of material is used for maintenance and small repair works because it can be placed without heating at the job site, unlike conventional hot mix asphalt; its usefulness depends on the interaction between the binder, aggregate, and the pavement defect being repaired.

What cold patch asphalt means in technical terms

Cold mix asphalt relies on bituminous binder coating and holding aggregate particles together. For pavement maintenance, the aim is to produce a mix that can fill potholes, edge breaks, or local surface defects, be compacted after placement, and gain serviceable strength under traffic. Cold patch materials are typically stockpiled and applied without heating equipment, which makes them practical for urgent and small-scale repairs.

Technical context of this standard

From the title, this TSE record is clearly directed at cold mix asphalt used in pavement repair; however, the supplied scope is empty, so the specific tests, numerical limits, production details, or acceptance criteria required by the standard cannot be inferred here. In general, standards of this type provide a shared technical language for matters such as gradation, binder content, workability, compaction behavior, and suitability for road repair use.

The referenced standards point to common material and test concepts used in asphalt technology. Aggregate grading, fines content, breakage/resistance properties, and bituminous material characterization are central to understanding repair-mix performance. For that reason, this document is relevant not only to pavement materials but also to engineering and procurement workflows that need a defined vocabulary for cold-applied asphalt repair products.
