Sustainable Pavement Maintenance Technology in Egypt
Cold In-Place Recycling (CIR)
When defects are concentrated in the asphalt pavement layers, such as those caused by climatic conditions, including longitudinal and transverse cracks that do not penetrate the base layers, and raveling of the surface layer.
Advantages of using CIR Technology
- It reduces maintenance costs by up to 30% compared to traditional road maintenance methods.
- It preserves 50% of quarry resources as it reuses all old pavement materials, including bitumen and aggregates.
- It permanently addresses structural defects, providing a suitable surface for paving.
- It improves the structural section of the road by producing a strong binder layer that prevents reflective cracks.
Full-Depth Recycling (FDR)
When pavement defects reach the stage of collapses in the asphalt and base layers at the end of the road's design life, and the structural layers can no longer bear the loads.
Advantages of using FDR Technology
- It reduces maintenance costs by up to 40% compared to traditional road maintenance methods.
- It preserves 90% of quarry resources as it reuses all old pavement materials, including bitumen and aggregates.
- Partial road closure and full-width reopening daily after completing road compaction.
- It permanently addresses structural defects, providing a suitable surface for paving.
- It improves the structural section of the road by reducing the need for new asphalt layers.
Micro Surfacing Technology
When severe aging and distress occur on the pavement surface, whether asphalt or concrete, along with the appearance of minor initial cracks.
Advantages of using Micro Surfacing Technology
- It preserves more than 90% of quarry resources compared to traditional methods.
- It reduces greenhouse gas emissions and decreases the use of petroleum materials by 80% compared to traditional methods.
- It allows the road to be reopened for traffic within one hour after work completion.
- It protects the pavement surface from weather effects and rain, lasting up to 5 years.
