RUNWAY RUBBER DEPOSIT REMOVAL
Airfield Pavement Friction & Safety Management
Runway rubber deposit accumulation is a critical airfield pavement maintenance issue affecting runway friction characteristics, aircraft braking efficiency, and wet runway operational safety.
During aircraft touchdown, tires rapidly accelerate from zero rotational speed to landing speed, generating intense frictional heat and depositing rubber particles onto the runway surface, primarily within touchdown zones and aircraft wheel paths.
As rubber accumulation increases, pavement macrotexture and groove effectiveness gradually reduce, resulting in:
* Decreased skid resistance
× Reduced braking action
_Loss of directional controllability
Reduced surface drainage capability
X Increased hydroplaning potential
X Deterioration of wet runway performance
Critical Rubber Accumulation Areas�Runway touchdown zones�Main wheel path regions
High aircraft movement landing areas
First 900-1200 m of runway pavement
Runway Surface Monitoring & Inspection
Typical runway surface evaluation includes:
V Continuous Friction Measuring Equipment (CFME) testing
V Surface texture depth assessment
V Groove condition inspection
V Drainage performance evaluation
V Visual rubber contamination assessment
Friction testing is generally performed along aircraft wheel paths approximately 3 to 6m from the runway centerline.

1. Sub-Grade (150 – 300 mm):-

The bottommost layer, typically made of compacted soil or natural ground. It provides the foundation for the road structure.

2. Sub-Base (100 – 300 mm):-

A layer above the sub-grade, often made of granular material. It helps distribute loads and improves drainage.

3. Base Course (100 – 300 mm):-

Provides structural support to the road. It's usually made of crushed stone or other granular materials.

4. Binder Course (50 – 100 mm):-

A layer of asphalt mix that provides additional strength and helps bind the surface course to the base.

5. Surface Course (25-50 mm):-

The topmost layer of the road, made of asphalt or other surfacing material. It's designed for direct traffic interaction, providing a smooth and durable surface.

6. Tack Coat:-

A thin layer of bituminous material applied between layers (like between the binder course and surface course) to ensure bonding.

7. Seal Coat:-

A thin layer applied on top of the surface course to protect the road from water ingress and improve surface texture.
