A bitumen additive used to improve cohesion in emulsions made using paraffinic bitumen.
CDM is a bitumen additive. It improves the cohesion build-up of micro-surfacing made with paraffinic bitumen. CDM can also be used for rapid setting emulsions to increase their viscosity and speed-up the cohesion build-up of the emulsion for surface dressing application.

CDM must be protected from exposure to water and to long-term exposure to atmospheric moisture. Water may also flash/splash when added to the hot bitumen. Atmospheric moisture contamination takes place slowly on the additive surface exposed to moist air. When in use, protect from rain and seal tightly when not in use.
Do not leave small amounts in containers for long periods before using it. Inspect the storage container and all seals for damage or leaks.
CDM must be protected from frost. Continued cold weather storage can lead to major increase in the viscosity of the CDM. This can lead to difficulties in pumping the additive.
