Mastic asphalt

Mastic asphalt is a bituminous mixture consisting of sand, filler and possibly stones and one or more additives. It is mainly delivered in bulk. Repair mastic asphalt is sometimes also supplied in the form of so-called ‘breads’ or ‘tiles’.

The main applications of mastic asphalt are:

• Sealing and protection layers on bridge decks
• Top layers of bicycle and footpaths
• Water channels
• Repairs
• Roof car parks
• Floors

• On a regular basis, samples are taken at the site in the presence of COPRO.
• These samples are tested by the producer (in the presence of COPRO) and by an externally accredited laboratory.
• Inspection of the raw materials used, daily tests, the production process …
• Inspection of the laboratory used by the producer for self-monitoring.

Indication of PTV 865, COPRO and the code of the technical datasheet (quick code, available at extranet.copro.eu) on the delivery document (with pre-printed receipt number).

• As part of the preliminary studies, the producer carries out a series of tests in advance. COPRO monitors this. Only when these test results are compliant will the producer put the product into production.
• The composition of the manufactured products is thoroughly checked daily by the producer.
• Supervision of the raw materials used.
• Supervision of the production process and the formula.

Moreover, the quality of the laid product is also determined by the preparatory work carried out and respecting the various parameters for laying such as layer thickness and temperature.
