PAVEMENT CORE DRILLING MACHINE AZA0962

Working Principle & Design

The AZA0962 operates on a rotary coring principle using a diamond-tipped core barrel driven by a powerful motor. Depending on application requirements, the unit is available with petrol, diesel, or electric drive options, making it suitable for both remote field conditions and fixed laboratory environments.

The machine is mounted on a rigid steel frame or trolley, ensuring excellent stability and vertical alignment during drilling. An integrated water cooling system continuously supplies water to the cutting zone, which:

• Cools the diamond bit

• Reduces friction and wear

• Flushes out debris

• Produces clean, damage-free core samples

The controlled feed mechanism allows smooth penetration through pavement layers, ensuring maximum core recovery and dimensional accuracy.

Key Features

• High-Precision Core Extraction
  Produces intact, uniform cylindrical core samples essential for accurate laboratory testing.

• Diamond Core Bit Compatibility
  Suitable for drilling through asphalt, concrete, and reinforced concrete with minimal vibration.

• Robust Construction
  Heavy-duty steel frame ensures stability, durability, and long service life under harsh site conditions.

• Water-Cooled Drilling System
  Enhances cutting efficiency, improves core quality, and extends diamond bit life.

• Portable Field Design
  Engine-driven variants with wheels enable easy transport and on-site operation.

• Controlled Feed Mechanism
  Allows operator control over drilling speed and pressure for different pavement materials.

Applications

• Pavement layer thickness verification

• In-situ density and compaction assessment

• Asphalt and concrete material analysis

• Compressive strength and modulus testing

• Pavement failure investigation and forensic studies

• Highway, airport runway, and bridge evaluations

• Quality control in road construction projects

The AZA0962 is widely used in accordance with IRC, MoRTH, and ASTM C42/C42M guidelines for pavement core sampling and testing.
