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.
- Binder: penetration, ductility, softening point, flash and fire point, and viscosity.
- Mix: Marshall stability and flow value.
- Aggregate: gradation.
- Modified binders: PMB and CRMB.
- Cold-mix and warm-mix asphalt: qualification.
- Delivery: through a qualified partner laboratory under TCR's coordination, sampling oversight and reporting.

Governing Standards
The road-materials scope is governed by the designations below, with penetration tested to IS 1203 and viscosity to IS 1206.
| Test | What it measures | Standard |
|---|---|---|
| Penetration | Binder consistency and grade | IS 1203 |
| Viscosity | Binder flow resistance | IS 1206 |
| Paving bitumen | Binder specification and grade | IS 73 |
| Modified bitumen (PMB, CRMB) | Modified-binder performance | IRC SP 53 |
| Flexible pavement design | Pavement thickness design | IRC 37 |
| Bituminous mix acceptance | Road and bridge works specification | MoRTH Specifications for Road and Bridge Works |
Delivery and Oversight
Because the bituminous work runs through a qualified partner laboratory, TCR retains sampling oversight and issues the reporting, so the client keeps a single accountable point of contact for road-materials acceptance.
- What TCR retains: sampling oversight and the reporting, so the client keeps a single accountable point of contact.
- Specifications: Indian Roads Congress for state and national highway works, and the MoRTH Specifications for Road and Bridge Works.
- Complements: TCR's in-house pavement evaluation and concrete testing.
The scope aligns to Indian Roads Congress specifications for state and national highway works and to the MoRTH Specifications for Road and Bridge Works, and it complements TCR's in-house pavement evaluation and concrete testing.
