Cold Asphalt Products from NRPT Asphaltica
Interested in Asphaltica® and the benefits of cold asphalt applications? At NRPT Asphaltica, we specialise in providing this high-quality asphalt product for construction projects worldwide. Using modified polymers, this product is ideal for repairing potholes and deformations on roads permanently, where asphalt has become worn down by traffic and loads acting on it over time. Get in touch today for further details.
Asphalt is a natural component of most oils that can be mixed with sand and gravel. Due to its versatility and easy handling, it is widely used in different branches of construction, including road paving and waterproof wall and roof coating.
However, asphalt requires effective maintenance over time to keep roads in good condition. Like asphalt, Asphaltica® is waterproof, adherent, and cohesive, but it’s also capable of resisting high instantaneous stress from traffic and other loads. This makes it ideal for pavement construction.
This asphalt mixture is produced in the cold, which enables for immediate application in all conditions or storage for up to a year, depending on your needs.
- Waterproof, High-Quality Mixture
- Produced in Cold, Suitable for Cold Mixing and Application
- Suitable for Potholes, Sinks and Sides, Cuts for Business Services, Cornering, and Fractures in Hydraulic Concrete
- Optimal Results in Any Climate, from Production to Application
- Suitable for Bulk or Weather Storage for at Least One Year
- Very Easy to Apply, including Cleaning, Filling, and Compaction
- Does Not Stick to Vehicles or Immediate Traffic, Unlike Other Hot Mixes
- Environmentally Friendly, with No Solvents,
The simplicity and feasibility of this technologically modified asphalt allow you to increase the productivity of maintenance crews by at least 100%. Equally, the versatility of the asphalt allows for work to be scheduled at any time of day or night. It’s also suitable for immediate application in all weather, including rainy and cold days.
Asphaltica® does not use asphalt cement in liquid form. This paste is used for hot asphalt to adhere to the surface where it is used. Due to its molecular compound, our additive does not require any bond or harmful solvents. On the contrary, the polymer ties the molecules so that they remain attached without penetrating the surface.
What’s more, our product does not emit the harmful gases that come with hot applications. We all recognise the unique smell of bitumen and asphalt, and environmentalists have found that these vapours (VOC) are very harmful to the environment and our health. Our Asphaltica® formula requires hydrocarbon molecules to stay stuck to the rest of the polymer, and therefore doesn’t pollute the environment in its gaseous form.
Typically, a conventional plant consumes more than 50 litres of diesel an hour for burners alone, so our burner-free process has a direct benefit to the environment. Furthermore, asphalt trucks do not require cleaning after use and our product does not leave burns or dirt on contractors’ outfits.
This bituminous patching mix is designed to be applied in the ambient temperature range of 50° (degrees) to 100° F. The mixture will provide satisfactory coating, workability and adhesion characteristics while functioning during cool to hot or dry to wet climatic conditions. Once in place and compacted, Asphaltica is virtually unaffected by changes in weather conditions.
Liquid Asphalt Blend
The liquid asphalt component used shall be either an AC-20 or AC-30 conforming to the specifications of the Florida Department of Transportation, a diluent which complies with the requirements and applicable specifications of the American Petroleum Institute (API), and a polymer additive of high quality that improves cohesion and adhesion properties and is capable of passing AASHTO-T-182 as modified herein.
The gradation should comply with the following limits except in the case where other studied and approved aggregates should be required by the agency.
