Overview

TCR Engineering, a NABL ISO/IEC 17025:2017 accredited laboratory (NABLT0726MH18640) in Navi Mumbai, coordinates bitumen and bituminous-mix testing through a qualified partner laboratory, with TCR retaining sampling oversight and reporting. The scope covers penetration, ductility, softening point, viscosity, Marshall stability and modified bitumen, aligned to Indian Roads Congress and MoRTH specifications for highway works.

Bitumen and bituminous-mix testing is delivered through a qualified partner laboratory under TCR Engineering's coordination, sampling oversight, and reporting. The scope covers bitumen penetration, ductility, softening point, flash and fire point, and viscosity; Marshall stability and flow value for bituminous mixes; aggregate gradation; modified bitumen (PMB and CRMB) testing; and cold-mix and warm-mix asphalt qualification, aligned to Indian Roads Congress specifications for state and national highway works.

What Bitumen and Road-Materials Testing Covers

Bitumen and bituminous-mix testing is delivered through a qualified partner laboratory under TCR Engineering's coordination, sampling oversight, and reporting. The scope runs from binder consistency to full mix qualification, aligned to Indian Roads Congress and MoRTH specifications for state and national highway works.

The scope covers bitumen penetration, ductility, softening point, flash and fire point, and viscosity; Marshall stability and flow value for bituminous mixes; aggregate gradation; modified bitumen (PMB and CRMB) testing; and cold-mix and warm-mix asphalt qualification.
