"BS 5273 : Dense tar surfacing for roads and other paved areas

This standard covers the all aspects of DENSE TAR SURFACING including composition, manufacture, and transport.
It also includes in the appendices guidance notes on the use and laying of this material.
It MUST be noted this material can be difficult to lay if you are not aware of the way it MUST be handled, it is a job for contractors familiar with this material.
N.B. DENSE TAR SURFACING is a quick setting material, low temperature working should be avoided.
It tends to be used where there is going to be oil droppings, e.g. parking areas, as TAR is far more resistant to softening from oil than BITUMEN."
