Viaflex SAMI
Stress Absorbing Membrane Interlayer
Viaflex SAMI (Stress Absorbing Membrane Interlayer) is a fine graded, polymer modified asphalt specifically designed for overlays onto concrete, cement bound bases, or where movement of underlying pavement layers is likely to result in reflective cracking.
How it works
Through the use of a highly modified bitumen binder and selected fine aggregates, Viaflex SAMI acts to absorb the stresses from movement in
the underlying layers whilst eliminating the need for expensive grid systems.
Product Availability
Viaflex SAMI is produced at all Cemex Asphalt supply plants.
Due to the requirement for polymer modified bitumen, minimum volume and notice period may apply at some locations.
Viaflex SAMI is particularly suited for installation between March and September however it is possible to install all year
round, advice for winter installation can be provided by Cemex technical department.
Delivery
VIAFLEX SAMI should be delivered or collected using a suitably insulated and sheeted delivery vehicle. An appropriate release agent such as water or vegetable oil should be used in delivery vehicles. Diesel should not be used as a release agent to clean tools and equipment as it has a detrimental effect on asphalt.
Our network of collect plants also sell Leoclean, a heavy-duty cleaner which is ideal for removing mineral oil-based substances
such as bitumen and tar. Additionally, we have a wide range of emulsions, sealants, truck sheets and tools to meet your everyday needs.
