LTCRTC (L&T Construction Research and Testing Centre) handles testing services and R&D on construction materials, and construction methods. It has a full fledged laboratory with sophisticated equipments to test all construction materials such as prestressed strands, reinforcement rods up to 50mm diameter., flat steel plates, bolts etc upto 100T capacity  in compression, tension and bending. The 10T UTM can simulate variety of fatigue loading on asphalt mixtures, concrete and granular materials to determine mechanical parameters like resilient modulus, poisons ratio, etc., . The basic construction materials like cement, fine aggregate, coarse aggregate, concrete blocks, bricks, plywood, water, chemical admixtures, geotextiles, soil, rock and asphalt can be evaluated as per national as well as international standards.

LTCRTC laboratory has acquired NABL (National accreditation board for testing and calibration laboratories) certification for mechanical and chemical testing of construction materials. About 112 tests were approved under this accreditation. It is the first major testing centre got accredited by NABL for testing on wide varieties of construction materials by a construction company in India.

LTCRTC focuses its study on innovation of new construction materials and techniques of construction. The center also conducts prototype testing, field investigation on structures by NDT techniques.
