| Use advice for data set | Type of EPD: Cradle to gate with options, modules C1-C4, and D. Module A1: Production of ancillary materials. Module A2: Transportation to the quarry. Module A3: Aggregates extraction, crushing and sizing at the site and waste treatment. Module C1: Mechanical removal of unbound aggregates with a hydraulic excavator. Module C2: Transportation of the recovered aggregates to a reuse site. Module C3: Reuse of unbound aggregates in another similar project, re-laid using a hydraulic excavator. Module C4: No aggregates are expected to reach landfill. Module D: Credits from the avoided production of primary aggregates. Burdens: none (no further processing assumed). | |||||||||||||||||||||||||||
| Technical purpose of product or process | Tarmac uses sand and gravel as essential aggregates across its construction materials, particularly in the production of concrete, mortar, and asphalt. These materials provide strength, stability, and workability, making them ideal for use in foundations, sub-base layers, drainage systems, and structural backfill. Their versatility also supports applications in landscaping, sports surfaces, and specialist mixes like ballast for fencing and kerbing. | |||||||||||||||||||||||||||

| Technology description including background system | Sand and gravel are naturally occurring aggregates sourced directly from natural deposits. Sand consists of fine particles typically whereas gravel is made up of larger fragments. Tarmac sources these materials from quarries across the UK. Once removed, the raw material is transported to nearby processing plants where it is washed to remove silt and clay, then screened and sorted into various sizes for use in concrete, asphalt, ballast, and landscaping products. | |||||||||||||||||||||||||||
