Fatigue craking (crocodile craking) repair

Fatigue craking (crocodile craking) repair

Fatigue cracks are irregular rupture of bituminous pavement are shaped figure thin, deep crevices come from surface exfoliation, cracks and pores. Unsealed cracks transverse or longitudinal bituminous pass fatigue cracks.

Fatigue cracks or crocodile cracks are treated as serious damage to bituminous pavement, which leads to lower carrying copacity of surface by allowing the penetration of water and de-icing agents to lower-lying layers of pavement structures.

Euroasfalt company has proven technology and specialist equipment to repair crocodile cracks, which were the initial degradation. The security cracks is used when opening the slits is from 1 mm to 2 mm. Cracks more degraded, you can only fix it by resurfacing.

The basic material used in the repair of fatigue cracks is a special grout, which at low temperatures retains the properties of the plastic and complies with the standard EN 14 188-1 (PKN-March 2005) and meets European standards. The mass of a stress-strain properties (such as rubber) and a high adhesion to the walls of pure asphalt. Using other masses or asphalt emulsion does not give the desired results, (photo 1) because they are not plastic and at low temperatures followed by re-rupture.

Unsealed cracks longitudinal and transverse cracks pass mesh. Euroasfalt has proven technology that I use for over 20 years to repair cracks mesh. Cracks more degraded (fot.2) can only fix it by resurfacing.
