The National Highways Authority of India (NHAI) and the National Test House (NTH) signed a Memorandum of Understanding (MoU) on December 30, 2025, at NHAI Headquarters in New Delhi to enhance quality, safety, and transparency in national highway construction. The MoU was signed in the presence of Bharat Khera, Additional Secretary, Department of Consumer Affairs; Santosh Kumar Yadav, Chairman NHAI; and Dr. Alok Kumar Srivastava, Director General of NTH. Under the agreement, NTH will undertake independent and third-party testing of construction materials — including bitumen, steel, cement, geosynthetics, electrical components, and safety-critical systems — used in highway projects at its 8 regional laboratories across India. NTH, established in 1912 under the Ministry of Consumer Affairs, is India's premier government testing and quality certification body. The MoU also provides for NTH to offer digital test reports, technical support to NHAI's regional offices and project implementation units, expert evaluation in complex cases, and capacity building through training programmes for NHAI officers. The agreement aims to address systemic quality lapses in highway construction by introducing independent third-party scrutiny, replacing reliance solely on contractor-supplied quality certifications. India's National Highway network now exceeds 1,46,000 km and NHAI manages approximately 49,000 km — making robust quality assurance mechanisms critical for road safety and infrastructure durability.
