The concept behind reconstructing concrete roads (concrete pavements) whilst in use
The intensity of use of important transport routes, such as motorways and trunk roads, is ever-increasing. Specific transport surfaces made from concrete, such as roundabouts, bus stops, etc. are also being used much more than before. The condition of this infrastructure is showing an ever-higher need for repair. The operators are therefore increasingly looking for repair methods, which disrupt traffic as little as possible.
With Concretum® Q-FLASH 2/20 rapid-hardening concrete, transport surfaces made from concrete can be replaced in a few hours, overnight.
Off-peak periods such as weekends, nights or days, between 10 a.m. and 4 p.m., are selected in order to carry out concrete replacement work effectively. During these periods, the concrete pavement is replaced in single carriageway sections, while the traffic is diverted to the other lanes. During peak traffic times (mornings and evenings during the week) all the lanes can be used without restrictions.
Where there are individual damaged slabs or areas, the concrete can be poured manually. When repairing large areas, entire lanes can be replaced in one go, by machine, with a concrete paver.
For small repairs and when replacing broken edges, the rapid-hardening repair concrete Concretum® Q-CON and the rapid-hardening repair mortar Concretum® Q-REP G can be used. These are available in bags.
