content name:
  Over a three-year period, the tyre/road noise and the pavement texture were periodically measured on a series of 21 full-scale sites situated in urban areas with a speed limit of 50 km/h. The study involved a wide range of noise-reducing asphalt mixtures, including semi-dense macro rough asphalt AC MR and porous asphalt PA. It has been shown that the acoustic performance decreases asymptotically as a function of traffic volume. For PA the decrease can be delayed provided the pores do not become clogged by dirt. According to the current results, AC MR shows promising acoustic and structural performance. AC MR test stretches may achieve acoustic lifetimes of up to 10 years depending on the traffic volume.

The similarity algorithm calculates how much two contents in the system are similar to one another. So far, similarity is calculated based on similarity of the project type, area of interest and user type. Generally, if two contents have more parameters in common they are more similar to each another. More information.
