Highly frequented traffic areas are characterised by very short time windows for construction and repair work. When using in-situ concrete, there are risks of weathering and material properties with regard to setting, which can lead to delays. These risks can be minimised by using precast slabs.
Replacement of damaged slabs or parts of slabs as well as lane wise replacement in any kind of concrete traffic areas (motorways, aircraft movement areas, industrial areas etc.)
Particularly suitable for highly frequented areas such as motorways, airport road surfaces and bus stops
Repair of cross joints with round precast slabs
Powerful large-scale equipment to produce separating cuts
Excavator for lifting out damaged slab parts and placing the concrete
Undersealing and, if necessary, mobile crane (external)
Screeds and paver finishers for surface treatment
HESTER –
innovative repair
The “Hybrides Ertüchtigungssystem für die Straßenerhaltung unter
Einsatz neuer Werkstoffe” (Hybrid upgrading system for road maintenance using new materials” – HESTER for short – was
developed in a network of strong partners and is a precast-based surface and repair system
that offers an innovative
and pioneering method to repair urban traffic areas, such as bus stops,
junctions and roundabouts. More information at www.hester-system.de
Special drill for round precast slabs
Inserting a round precast slab
Repaired cross joints
Pre-integrated paving slabs possible
Precast slabs to replace slabs
Height adjustment over adjacent slab
Independent support of the precast slab
Monitoring of undersealing work
Application in new construction and for repairs (e.g. fire damage)
High quality through production under protected conditions
Built-in equipment (e.g. airport lights, empty pipes, shafts) can be pre-installed at the factory, which means a reduced workload on site
Surface adaptable to existing construction
Various versions of height adjustment depending on the support option
Precast slabs can be laid in any weather
Guaranteed time to reopen the area to traffic by excluding the risk of setting time risk
Short closure times
