Asphalt mixtures
Asphalt mixtures are a composition of stones, sand, filler, a binder and possibly additives (such as colourants) and/or reclaimed asphalt.
Cast iron road materials
These are devices for covering manholes in traffic and pedestrian areas with an opening of at least 700 mm (PTV 800 and PTV 801) and sewer parts and devices made of cast iron for water collection and drainage (PTV 802).
Cold asphalt
Cold asphalt is a mixture of stones, sand, filler and possibly additives with an emulsion, flux bitumen or synthetic binder. Due to this binder, the asphalt can be processed cold. It is available in bags or buckets, but also in bulk.
Elastomer sealing rings
Elastomer sealing rings are made of vulcanised rubber. The rings ensure that the seal between two connected parts is watertight within the scope of application.
Gabions
Gabions are baskets made of netting with a hexagonal mesh of steel wire with a zinc-aluminium coating and possibly plastic coating, formed by a cage (front, back, base and cover), sides and any partitions.
Geogrids
Geogrids are flat structures, consisting of a regular network with tensile and interconnected elements in the nodes. They are constructed using a perpendicular network structure.
Geotextile
Geotextiles are permeable, woven or non-woven fabrics that are used in combination with soil in hydraulic and road engineering constructions. The materials used to manufacture geotextiles are usually polypropylene and polyester, but also polyethylene, nylon and optical fibre.
Hydraulically bound mixtures
Hydraulically bound mixtures consist of aggregates, sand, water and binder. These mixtures (including sand cement, lean concrete, and stabilised rubble foundation) are produced by a central mixing plant.
Joint fillers and sealants
Hot-processed joint fillers and sealants consist of a mixture of petroleum bitumen, polymers or elastomers, resins and optional additives. It is delivered in boxes or metal drums.
Mastic asphalt
Mastic asphalt is a bituminous mixture consisting of sand, filler and possibly stones and one or more additives. It is mainly delivered in bulk. Repair mastic asphalt is sometimes also supplied in the form of so-called ‘breads’ or ‘tiles’.
