Block paving driveways are one of the more used pavements since it looks nice, and it is an affordable price for any type of wallet size. It will also complete your homes outside look, and attract more attention than ever before.
These asphalt paved driveways consist of rock particles, sand, and asphalt cement, which make it flexible and durable at the same time. New asphalt is by far the most flexible because it still retains many of the lighter hydrocarbon oils that make up its DNA structure. Crushed gravel makes up the foundation on which the asphalt is laid, to promote stability of the asphalt structure.
Using a tight string line to get the screeding rails to the correct finished height prior to screeding the sand, check for level or falling towards any drains, a 1:60 fall is required, that’s 1” in height to 60” in length minimum fall to ensure any surface water drains into your drainage system or soak-a-way.
Make sure the line is tight as you don’t want any sag in your line, this will give a false reading with your levels which could result in your finished driveway holding water.If your driveway is falling towards the house, then simply reverse the fall and levels from the pavement towards an existing rain water gully. If this isn’t possible, you will have to install drainage channels along the front of the property. Water should then be directed into a soak-a-way within your garden area.
