The lack of adherence is responsible for a high percentage of accidents, causing great efforts to be made to achieve roads with good non-slip conditions.

From the point of view of road safety, it is necessary to analyze the phenomenon of adhesion between the tire and the pavement, which decreases together with the degradation of the surface characteristics of the road surface.

 

For road traffic to take place safely and comfortably, the road surface must meet certain surface characteristics. One of the most important is skid resistance, which allows drivers to accelerate, brake and change direction without the vehicle slipping.

 

Slip resistance can vary due to four phenomena, which do not occur individually, but rather more than one can occur at the same time: Mechanical wear mainly due to polishing due to the action of traffic, stripping of the binder, variations seasonal and finally, the effect of aging.

Aquaplaning effect.

Aquaplaning is essentially associated with the macrotexture of the pavement. It occurs when a film of water separates the wheel from the road surface. This phenomenon depends on the speed and weight of the vehicle, the characteristics and condition of the tires, the macro-texture and the thickness of the water on the pavement.

 

Although there are many variables that intervene, the fundamental one is the presence of water in the pavement with a critical depth.

 

The hydroplaning risk of each road section is determined by studying the topography of the pavement: its geometry, the superelevation and the macro texture that determine its ability to evacuate water.

conclusion

Over the last few years, we have carried out different hydro-grinding works throughout the peninsula in order to increase road safety REDUCING ACCIDENTS OCCURRED TO ZERO.
