Tufflex® HD/HD+ is a unique asphalt surfacing solution designed for very heavy, slow moving traffic. It contains a polymer modified bitumen (PMB) with an exceptionally high softening point.
PMB is at the heart of a unique solution that offers good protection against damage caused by heavy, slow moving traffic. The product also contains fuel resisting properties.
Tufflex HD/HD+ is available in 6mm, 10mm, 14mm and 20mm nominal sizes and can be laid between 30mm and 150mm thick using a traditional asphalt paver with a 6-10 tonne roller in combination with conventional paving equipment in line with BS 594987. As a single layer application Tufflex HD/HD+ can halve the installation time of traditional material.
Please note: Minimum 7 days’ notice required to stock specialist binder.
Benefits
The main advantages of Tufflex HD are:
- Cost-effective over the whole life
- Very high deformation resistance
- Low air void which prevents water ingress
- Fuel resisting properties
- Good workability
- Has a resistance to elevated temperatures from chemical attacks from leachates
- Good load spreading ability from very heavy, slow moving traffic at higher temperatures to prevent wheel track deformation
- Increased stiffness
- 100% recyclable
