RAP

Requested in many projects, RAP (Reclaimed Asphalt Pavement) has become a sustainable and economically advantageous practice. By acquiring an ERMONT MARINI equipment, you can work with up to 30% RAP, bringing the best of technology together with the best in material cost reduction to your projects. The RAP technology of ERMONT MARINI equipment is designed to enable the growth of your business, adding value and facilitating your operations.

RAP is gradually introduced into the dryer drum, ensuring lower impact on production, better mix quality, and reduced gas emissions.

To use RAP, the following should be considered:

• The milled material must be processed by specific equipment and laboratories before being added to the mix;
• The laboratory responsible for enabling the use of RAP must be specialized and reliable;
• To determine the amount of virgin material that should be added to the mix, the type of material being used must be known;
• The bitumen content in the RAP must be known. This is due to the fact that this material’s structure and properties are altered because of its age and prior use. The previous use of the material causes structural changes due to the oxidation process resulting from exposure to air, increased bitumen viscosity (which can cause difficulties when mixing), among others.
