The ultimate surfacing solution for concrete pavements
Over 1,200km of concrete pavement are thought to be in use on Highways England’s strategic road network, with an even greater length in existence across the local authority network.
The thin asphalts used to overlay this concrete frequently suffer from reflective cracking caused by thermal expansion in the underlying concrete and the effects of traffic loading. This cracking eventually leads to water ingress and failure, requiring costly remedial work and causing delays for road users.
To meet this challenge Tarmac has introduced a high performance asphalt stress absorbing membrane interlayer (SAMI) that is proven to resist these stresses, for long-term protection of the asphalt overlay.
Proven Resistance to Cracking
ULTIMAT SAMI is designed to provide exceptional resistance to the cracking caused by thermal and traffic induced movement in underlying concrete layers.
ULTIMAT SAMI is designed to achieve low insitu voids helping to protect the pavement from water ingress damage.
Longer Lasting Results
Long term monitoring of completed contracts has shown overlays using ULTIMAT SAMI to outperform conventional asphalt solutions.
Improved Asset Management
Extended pavement life, longer resurfacing intervals and lower maintenance requirements mean improved return on investment.
At the end of the overlay’s life ULTIMAT SAMI can be removed by standard cold planing and the arisings can be easily recycled back into hotmix asphalt.
All Tarmac products are manufactured in the UK and certified under BES 6001 Responsible Sourcing. ULTIMAT SAMI is also designed to be more durable than conventional materials making it a more sustainable long-term solution.
ULTIMAT SAMI can be used in combination with our Ultilayer flexible surface course [link to Ultilayer page] and Pozament concrete repair products [link to Pozament on TBP site] for the ultimate concrete overlay solution.
