About

I am a Geo-Material Lab Engineer with 6+ years of experience in construction materials testing and laboratory quality control. I specialize in testing soils, aggregates, concrete, and asphalt in full compliance with international standards such as ASTM, AASHTO, and BS. My work includes: • ABC design, soil classification, Proctor, CBR, impurities analysis, and compaction testing • Aggregate gradation, specific gravity, soundness, clay lumps, angularity, sand equivalent, Los Angeles abrasion, and absorption testing • Concrete mix design, compressive strength testing, slump measurement, and trial mix evaluations • Asphalt mix design (Marshall & Superpave), stability, Gmm, Gmb, moisture susceptibility, and flow analysis • Supervision of asphalt plant production and quality of delivered asphalt mixes • On-site inspections to verify compliance with material specifications and execution standards I am certified and experienced in laboratory quality systems under ISO/IEC 17025 and ISO 9001, with a strong focus on data accuracy, traceability, and continuous improvement. I also oversee equipment calibration, detailed report preparation, and ensure full compliance with project specifications and timelines. Known for my attention to detail, consistency, and strong work ethic, I collaborate closely with consultants, contractors, and quality teams to deliver dependable and timely results. I’m always eager to grow technically and contribute to the success of high-quality infrastructure projects.
