Course Mixes - Macadams |
|
There
are three main wearing course materials. 6mm, 10mm and 14mm, and all
are used for specific jobs. Each mix can be individually tailored
to your specific requirements, for example: where extra drainage is
required an open texture can be specified which increases the amount
of stone used in the mix. This will slightly reduce the durability
of the surface but under some extremes may be necessary. The opposite
of open texture would be dense texture where the specification would
be to add in more fines, such as sand, stone dust etc. This creates
a smoother more durable wearing surface than normal. Good all round
drainage is essential in order to use this mix because it eliminates
any water seepage.
Specification for 6mm wearing course:- This is a very fine
mix which gives an excellent finish but does not have the strength
required for heavy traffic and is therefore used mainly for footpaths,
play areas and small household driveways etc.
Specification for 10mm and 14mm wearing course:- These mixes
are the preferred mixes for heavy traffic areas with each material
providing an excellent finish coat and both having the strength and
durability to resist wear by heavy traffic. 10mm is a particularly
good finishing material when extra fines and bitumen are added. This
mix is known as bungalow mix, highly recommended for household driveways
because of its neat finish and durability. We will determine the right
mix on survey after we have ascertained the amount of traffic in the
required area. |
