SUPERCLEAN 50

polymer modified asphalt type II (for use at warm mix)

Overview

Superclean 50 is a premixed modified asphalt for use in warm mix. It conforms to polymer modified asphalt type II.

Features

Superclean 50’s features differ with those of typical polymer modified asphalt type II in the following ways.
  1. Mixture manufacturing and construction can be performed at temperatures 50°C lower than conventional asphalt, greatly reducing the production of carbon dioxide (CO2).
  2. Mixture can be shipped at a lower temperature, reducing the time for traffic opening.
  3. When mixtures are manufactured at the same temperature as is used for typical polymer modified asphalt type II, the permissible construction period is extended significantly. As a result, quality can be more easily maintained during construction in cold or remote locations.

Relationship between the tamping temperature and compaction rate

Applications

  • For reducing CO2 emissions from manufacture when asphalt paving on routes with heavy traffic
  • To meet the need to early traffic opening when asphalt paving on routes with heavy traffic
  • When asphalt paving on routes with heavy traffic where materials need to be available for extended periods, such as for construction during cold periods or for long travel distances to remote locations
