What is CIPR?

Cold In Place Recycling (CIPR) is an advanced and environmentally friendly technique in treating distressed road pavements. CIPR provides a more cost-effective alternative to pavement rehabilitation for both partial of total construction options.

The Application

Upgrading of Unsurfaced Roads

Provides unsurfaced roads with a durable black topped surface, eliminating dust and mud problems. Studies carried out in many countries show that economic benefits can be expected in the longer term, due to substantial reduction in maintenance costs.

Recycling Thin Asphalt Pavement Layers

Pavements where the distress is caused by aging asphalt layers of pavements can be effectively rectified by recycling a relatively thin layer. Cracking and surface degradation that occurs without severe rutting are indicators of such distress.

Structural Strengthening by Deep Recycling

Recycles tough pavements consisting of thick layers of hot-mixed asphalt. The process recycles and strengthens the material in the pavement of the existing road in a single operation. Superficial asphalt aging problems are able to be rectified and weaknesses that occur deeper in the pavement are able to be addressed.

The Operation

The recycling machine scarifies the existing pavement layers (to a maximum depth of 500mm) then adds either cement or bituminous materials or both as stabilizing additives before relaying it back on the same pavement area in a single process.

The Advantages

CIPR offers exceptional performance for road rehabilitation. CIPR represents the future of pavement technology, and with its proven track record, will replace conventional pavement rehabilitation methods.

Cost effective where operations use less manpower and machineries, and a shorter construction time. Saves around 20% of the investment in repair costs.
Versatile where pavements are now easy to construct through one pass operations, production is highly mobile, and causes less traffic disruption.

Ecologically Friendly where existing materials can be reused, causes less air pollution and conserves natural resources (quarry product).
