Material Testing Laboratory

The material testing laboratory deals with sampling of materials and carrying out quality tests on lateritic materials, aggregates, concrete mixes, steel, petroleum products and bituminous materials

5. Asphalt and Bitumen Tests

Asphalt compaction test

This process deals with asphalt mix controlling, sampling and compacting of asphalt mixtures by impact compaction.

Marshall stability test

Marshall stability test measures the load and flow rate of asphalt samples.

Theoretical maximum specific gravity (Gmm)

The theoretical maximum specific gravity (Gmm) of a Hot mixed asphalt mixture is the specific gravity excluding air voids.

Bitumen extraction test

This is used for determining the percentage of bitumen in bituminous mixtures.

Asphalt temperature check

The temperature of asphalt when it arrives job site is checked before and during laying.

Rolling bottle test

The test is used for determining the affinity between aggregate and bitumen

Dynamic Asphalt mix testing systems (Asphalt misture performance tester)

The tests cover all static and dynamic performance testing methods, including Stiffness/Dynamic Modulus, Fatigue Cracking, and Permanent Deformation tests.

Asphalt rutting & moisture damage susceptibility test

This test describes a procedure for testing the rutting and moisture damage susceptibility of asphalt aggregate mixtures using dynamic loading applications in the Automated Asphalt Pavement Analyzer (Automated APA) to simulate traffic.

Bitumen penetration test

It helps to identify the grade of bitumen based on its hardness, softness and consistency
