A report on the fabrication of concrete pavement with the application of anionic bitumen emulsion

- Beneficial effect of bitumen emulsion on the concrete frost resistance was noticed.
- Bitumen emulsion enhances the concrete waterproofness.
- Anionic emulsion profitably changes the structure of concrete porosity.
- Concrete composition suitable for the most severe exposure classes was selected.
- Laboratory research results were verificated in practice.

The problems of concrete degradation in pavements occur around the world, regardless of climatic zones, which is one of the chief factors in environmental corrosion. This article describes the final stage of Development Project No. 14 009 03 carried out by the Ministry of Science and Higher Education in Poland regarding the verification of laboratory research results with the construction of the Multimodal Reload Terminal within the Duty Free Zone in Małaszewicze, Poland. The Terminal concrete pavement was designed to expand and doweled in accordance with the national requirements and the paving layers was based on existing solutions. Concrete in the slab was modified with an anionic bitumen emulsion to reduce its water absorption and improve resistance to environmental aggression. To achieve the required consistency of the concrete mix superplasticizers were used. The use of bitumen emulsion allowed to achieve the concrete water absorbability to below 4% in comparison to reference concretes while at the same time retaining high F200 frost resistance. The technology of cement composites modified with anionic bitumen emulsion was successfully tested under real operating conditions with the creation of a concrete pavement capable of bearing high mechanical pressure in a corrosive environment.
