72% of the firm presents cracks in the filmed, anteroom of deteriorations graver

For the time being results practically impossible to find a stretch of road in Spain whose firm was not cracked. In concrete, and according to the first data of the audits that, each two years, the Spanish Association of the Road (AEC) realizar to the state of conservation of the group of the roads of the country (network of the State and autonomic network), 72% of the paving presents cracks in the filmed, a defect that, although it does not suppose any direct risk for the hygiene of the traffic, can cause important damages if they register intense rains, since the water penetrates in the cracks with effects nefastos for the internal layers of the firm. The situation aggravates in winter, when the water freezes , accelerating and aggravating the process.

Beside the agrietamiento, the loss of arid or of bituminous material of the paving and the ruts or deformations caused by the filmed of the vehicle are others of the deteriorations that, with greater frequency, can observe at present in the firm of the Spanish roads.

The superficial deteriorations are the preamble of others graver, designated “structural”, that are those that observe when confluyen in the paving cracks, disintegrations, deformations and potholes. At present, 12% of the Spanish roads presents structural deteriorations in more than half of the surface of the shod.

The superficial deteriorations affect to the comfort of the driving. However, the structural involve an increase of the risk, being able to arrive to be direct cause of dangerous situations for the circulation.

The preliminary report of the AEC puts of self-evident, besides, that 21% of the roads of our country has half or deep ruts. The ruts are longitudinal deformations of the bituminous mix that form following the filmed of the vehicles. They cause discomfort in the driving, although they can elevate the risk of accident in the network of high capacity, since, his concentration in the right lane moves the circulation to the left, reserved for the overtakings.

A deterioration in the surface of the firm does not represent, per , risk for the occupants of a car. Even less in the case of the heavy vehicles.

However, the motociclistas and cyclists are users whose hygiene yes can see engaged if they circulate by roads whose present paving superficial deteriorations.

The superficial deteriorations can correct with repavimentación, but the structural demand, in a lot of cases, reconstruction, requiring of investments much higher.

The auditss of the state of conservation of the road infrastructures have his origin in the Campaigns of Visual Inspection of the Network that the AEC began to realizar in 1985 with the aim to know the state of the paving and of the equipment, as well as to determine the necessary minimum investment to reach levels of suitable service.
