Laboratory
Overview
The Central Testing Laboratory is staffed by knowledgeable, experienced, and certified technicians and professional engineers, backed with industry knowledge and experience.
The Laboratory conforms with ISO 17025:2017 standard for testing and calibration of laboratory equipment. It provides stringent testing services as per international standards- BS, ASTM, and AASHTO, using fully calibrated state-of-the-art testing instruments with valid calibration certificates.
Asphalt
Bitumen
The Laboratory provides SuperPave mix (Superior Performing Asphalt Pavements) based on Strategic Highway Research Program (SHRP) asphalt research. The SuperPave mix design incorporates performance-based, asphalt material characterization based on environmental conditions for improved performance by controlling rutting, low temperature cracking and fatigue cracking.
