More roads get quieter paving
Rubber asphalt is manufactured by mixing rubber granules from crushed recycled car tires with the asphalt binder. The rubber compound is then added in the asphalt mill in the traditional way. The proportion of rubber in the finished asphalt is under two percent.
This type of asphalt has been used for 25 years in the United States. There it has been found to have a much longer service life than traditional asphalt, it has reduced noise and the proportion of particles along the way. This means profits for both the environment and the economy.
