| Bituminous
Surfacing Materials |
|
| There
are several types of bituminous materials that can be used for roads,
driveways, footpaths etc. Each has it's own specific quality for the
use it is intended for; eg. drainage, wearing and or traction purposes
among others. We at All American Asphalt and Tarmac survey each specific
job and decide on the ideal material required. This will be explained
to you by a member of our staff at the time of survey. |

| Basecourse
Mixes |
|
These
materials are used to give a good firm surface on which to lay a wearing
course material. They consist of a well graded large stone and dust
mix which gives a good matrix. Held together by bitumen, this gives
a well bound, dense material which is suitable for laying the wearing
course on. It is essential for al asphalt wearing courses to have
a Basecourse Macadam because of the density of asphalt that provides
ultimate endurance against wearing. This eliminates the risk of fragmentation
which may occur when you do not lay the correct basecourse.
It is not essential for all tarmac wearing course mixes, where a good
stone foundation can also provide the base course required on certain
jobs. For example: Household driveways, private roadways, play areas,
tennis courts etc. This can be further explained at time of survey. |
