Specifications for Dense Bituminous Macadam and Bituminous Concrete for Airfield Pavements (First Revision)

IRC 105:2019 specifies the requirements and procedures for Dense Bituminous Macadam (DBM) and Bituminous Concrete (BC) mixes used in airfield pavements. It covers material selection, mix design, construction operations, quality control, and testing methods to ensure durable, high-performance runway, taxiway, and apron surfaces. This standard is essential for engineers and contractors involved in airfield pavement design, construction, and maintenance, providing guidelines on bitumen grades, aggregate properties, layer thicknesses, compaction, and environmental considerations specific to airfield applications.
