Colouring recycled paving systems
When Vast Enterprises wanted to offer the construction industry a "green" alternative to conventional paving systems, it developed composite masonry paving made entirely of recycled tyres and plastic bottles.  In order to overcome the extreme blackness of the tyres, it used custom compounder RTP Company’s colour masterbatch for the pavers.

Available in three standard colours, plus additional special order colours, the
pavers are protected against colour fading and property degradation by a proprietary blend of stabilisers in the masterbatch.

Vast says its composite masonry pavers have proven to be an especially popular alternative for those seeking LEED certification for green building projects. In addition, Vast says it reduces the labour required to install traditional clay or concrete bricks. Also since its masonry is one-third the weight of other materials, this allows for quicker installations and easy transportation.

The pavers are shipped with underlying grids, manufactured in the same composite of recycled materials as the blocks. These grids are either 30 or 40 cm square depending on the size of the pavers chosen. During installation, the grids allow paved surfaces to be put down quickly and permit easy positive alignment, says the US company.
