Excel Brings Viscocel to Hillhead
28 March 2007

Hillhead 2007: 26 – 28 June
Stand number: P19

Excel Industries will be exhibiting its high performing, environmentally friendly, Viscocel bitumen modifier range at Hillhead 2007. Manufactured entirely from recycled newspaper, Viscocel is available in both loose fibre and pellet form – both of which will be on display.

Excel’s Viscocel fibres have been developed to provide a bitumen modifier designed to create tougher, quieter and smoother road surfaces. Because they are manufactured purely from recycled newspaper, the fibres are safe to handle and have an indefinite shelf-life.

Once dispersed in the asphalt, the fibres hold the bitumen in place by creating a lattice, which binds the material together, enhancing the bitumen’s ability to adhere to the stone aggregate. The lattice created by Viscocel’s long interwoven fibres, give the SMA more elasticity, making it less brittle and more able to withstand heavy loading.

Excel will be exhibiting Viscocel 315 Loose Fibre and Viscocel 450 Pellets. Loose Fibre can be added to the asphalt mix manually or fed through a Krendl blowing system. Viscocel 450 Pellets consist of compacted fibres held together by a specially created wax binder, which allows them to disperse easily and consistently in the asphalt mix for direct addition. Depending upon the plant’s production requirement, the pellets can either be supplied in pre-weighed low melt bags that can be directly added to the mix, in FIBC’s or by bulk tanker for automatic dosing through proprietary systems.

Viscocel has enjoyed a successful track record since its introduction over 15 years ago. SMA mixes incorporating Viscocel fibres have been tested in harsh road conditions and have repeatedly demonstrated high levels of impact resistance; a quiet, smooth and long-lasting performance and lowered levels of rutting and deformation.

The greater stiffness created by the addition of Viscocel means thinner coverings can be applied, whilst an increased durability extends maintenance intervals, leading to less disruption for drivers, and ensures optimum driving conditions creating a safer drive.
