Recent years have shown how serious the problem in Poland is the cracking of bituminous and concrete surfaces. In our conditions the most vulnerable to cracking in the pavements are semi-rigid structures and rigid pavements. This is especially true of roads built up to 2000, whose pavement construction, the type of materials used for construction, the technology of their construction, did not anticipate such heavy traffic with wheeled vehicles, traffic and speed. In time, untreated cracks subjected to atmospheric conditions caused further deterioration of the surface and increased problems.
Extending the service life of the surface at the present state of the roads becomes a prime task. This service is used for inexpensive, effective repair methods.
Fatigue cracks (crocodile cracks) should be treated as serious damage to bituminous pavement, which lead to lower carrying copacity of surface by allowing the penetration of water and de-icing agents to lower-lying layers of pavement structures.
Bad condition of facilities expansion is the most important problem of bridges in the country. The reason for this is the lack of effective and relatively low-cost load-bearing structures due to pressure from the wheels of vehicles on a contact bridge structure and roadway. The result of the lack of good bridge expansion joins is accelerated degradation of the surface, the carrier plate of the bridge, the ends of beams and supports due to the corrosive effects of freezing water and chlorides.
Tram tracks through the accumulation of water in the depth of pavement around the track, increasing noise and vibration. This is one of the most important problems that must be overcome in the rail transport in cities. Technologies involving the filling of an elastic embodiment, and a hydrophobic organic material, provides the desired effect. The use of durable tight filling connecting elements track with the road surface minimizes unwanted effects in the form of vibration, noise and insulate them from stray currents.
On the concrete surface is exposed to large forces that cause the concrete surface is subjected to forces dylatuje and eventually crack. This type of surface enforces slit in the form of so-called slots. dilatation. Cracks in concrete pavement are designed to eliminate or control cracks caused by contraction or expansion of the concrete slabs under the influence changes in temperature and humidity. Where you can not call artificial joints, concrete works causing micro-cracks – this is completely normal and does not cause damage to road use.
