Ever increasing traffic densities, higher axle loads, increased tire pressures and unfavourable wheel configurations result in increasing deterioration of asphalt pavements. This deterioration manifests itself in ravelling, rutting, surface cracking, fatigue and reflective cracking, resulting in dangerous traffic conditions, a shorter lifetime and higher maintenance frequencies.
By improving the asphalt mixture properties, the lifetime of the pavement will be extended. The best results are obtained by incorporating specific polymers to the bitumen. Sealoflex® comprises a group of high-performance polymer modified binders for use in heavy duty asphalt pavements (including design and build projects). Since its introduction in the early eighties, Sealoflex® has proved its value in practice in terms of durability and life cycle costs. Sealoflex® is manufactured and applied throughout Europe, The Middle East, India, America and the Far East.
Asphalt mixes based on Sealoflex® binders are characterized by:
These specific properties of Sealoflex® asphalt pavements provide excellent resistance to raveling, fatigue, permanent deformation, surface cracks and reflective cracking, also under extreme climatic conditions.
Sealoflex® bitumen can be cost effectively incorporated into asphalt pavement layers as follows:
Asphalt mixtures with Sealoflex® binders can be produced in any hot-mix asphalt plant. Sealoflex® can be used in all asphalt layers. The composition of Sealoflex® asphalt mixtures can comply with Highways Agency and Local Authority (ADEPT) specifications. To guarantee the highest quality, Sealoflex® is only manufactured in a plant according to strictly laid down procedures and supplied as homogenous material according to precise specifications. Technical supervision during the production and processing of Sealoflex® asphalt mixtures is available.
There is no specific equipment required for the processing of Sealoflex® asphalt mixtures.
