| What is the difference between tar and asphalt? |
Tar is a mixture of stone and bitumen and has an even grained appearance. Asphalt is a mixture of sand, lime and bitrumen. It is smooth and generally has white limestone chips or black precoated chips rolled into it.

| Is tarmac available in different colours? |
Yes - red, yellow and blue. However, the material price rises by an average of £100 per tonne.

| |
| Can you lay tar in all weather conditions? |
Yes... almost. In hot weather there are no adverse effects on the tar. In addition, cold weather is fine as long as the air temperature is one degree celsius on a rising thermometer. Finally, light rain showers are acceptable, prolonged heavy rain is not and may lead to standing water.

| How long before I can walk or drive on tar or asphalt? |
When the material has cooled. This is generally around one hour after rolling is complete.
