Description: These services include the rehabilitation of traffic areas, in particular the professional repair of damage to asphalt surface courses such as cracks, breakouts, and potholes. The rehabilitation is carried out using a hot-applied method, using a thermoplastic repair material—so-called plastasphalt. The goal is to restore the serviceability of the traffic areas and extend their service life. A hot-applied plastasphalt, whose composition is based on a modified 105/25 bitumen, is used as the repair material. The binder is supplemented with aggregates with a grain size of 0-4 mm in accordance with the Technical Delivery Specifications for Aggregates in Road Construction (tl Gestein-stb 04). The material also contains mineral oil additives (tax 400), lime-based fillers, as well as rubber and calcium components. The material is supplied and processed exclusively in tested quality, using products from the manufacturers Straßenflex GmbH or Aspa GmbH. The plastasphalt is heated to a processing temperature of 210 to 280 degrees Celsius before installation. It must be processed immediately after heating to ensure the material's full binding effect and flowability. Due to its thermoplastic properties, the material is suitable for year-round use, regardless of weather conditions. However, this requires short-term availability by the client, which the contractor must ensure. Repair is carried out in two standardized widths of 15 cm and 30 cm using a suitable screed. Larger damaged areas can also be repaired using a thin-skinned surface application if necessary to create a level and load-bearing surface. A suitable mastic asphalt mixer must be provided for processing the plastasphalt. This equipment, including fuel, heating equipment, transport equipment, and all necessary processing accessories (e.g., leveling shoes, watering cans, spatulas, smoothing tools), must be provided by the contractor. The equipment's operational readiness must be ensured throughout the entire contract term. The processing material used must comply with the relevant standards and exhibit the following technical properties: The softening point according to ring and ball (EN 1427) is between 120 and 135 °C. The density at 25 °C is 1600 to 2000 g/cm³ (according to EN 13880-1). The cone penetration at 25 °C is in the range of 0.5 to 0.8 mm (EN 13880-2). The elastic recovery after ball penetration at 25 °C is 7.2 to 7.7% (EN 13880-3). The flow length at 60°C is between 2.8 and 3.2 mm (EN 13880-5). The SRT value (Skid Resistance Tester) for determining skid resistance at 15 to 20°C is at least 65 SRT. The construction work is being carried out within the framework of a framework agreement with a term of four years. The work is being called upon by the client as needed. The contractor ensures that the rehabilitation measures can be carried out within short response times. All work must be carried out in such a way that the site can be opened to traffic immediately after the material has cooled down. The contractor is also responsible for traffic safety, the environmentally friendly disposal of excess material, and the restoration of the construction site to a proper condition. The rehabilitation work must be carried out in compliance with all relevant occupational health and safety measures and applicable regulations. High-quality and durable execution of the repaired areas must be ensured.
