Existing pavement oxidised and crackingOverlay with asphalt
The existing old road pavement has an unacceptable ride quality due to potholes and delamination.The work proposed is to overlay 50mm of asphalt over existing pavement for a length of 500 metres x 5 metres.
The pavement displays some block cracking and extensive crocodile cracking. The crocodile cracking is an indication that the pavement is deflecting excessively and will allow the ingress of moisture into the pavement causing premature failure. Some delamination of the overlay is also occurring due to the excessive deflections.Stabilisation of the pavement.
The pavement is heavily oxidised and displays significant crocodile cracking. The crocodile cracking is an indication that the pavement is deflecting excessively. The cracked pavement and kerb and gutter will allow excessive moisture to enter the pavement and promote premature failure.Stabilisation of the pavement including repairs to the kerb and gutter.
The existing seal is oxidised and stripped. The pavement is displaying cracking in some areas. In general the shape of the road is acceptable.The works involved milling and removal of the existing road seal and based layer. Laying 120mm of AC20 and 30mm of AC10 as final layer over the full width of the roadway.Total cost of proposed project is $127,978
Oxidised cracking pavement surfaceCrack sealing, re-water proofing and new bitumen surface
The existing seal is oxidised and stripped. The pavement is displaying cracking in some areas. In general the shape of the road is acceptable.The treatment will involve some heavy patching and the wearing course will be treated with a 30mm mill and fill operation with AC10 over the entire area and some kerb and gutter repair.Total cost of proposed project is $107,484
Rough and damaged surface in a high traffic volume area in vicinity of the HospitalImprove intersection drainage, shape and driving surface
The pavement is heavily oxidised and displays some block cracking and extensive crocodile cracking. Areas of the kerb and gutter are also extensively cracked and overturned. The crocodile cracking is an indication that the pavement is deflecting excessively. The cracked pavement and kerb and gutter will allow excessive moisture to enter the pavement and promote premature failure.Full reconstruction of the pavement including the kerb and gutter.
