| 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’s limestone is widely used across real-world construction and landscaping projects due to its strength, versatility, and reliable performance. It serves as a key aggregate in concrete and mortar mixes, providing structural integrity for buildings, pavements, and foundations. Its excellent drainage properties make it ideal for sub-base layers, driveways, and footpaths, helping to manage surface water and prevent flooding. In landscaping, limestone is valued for its clean, light appearance and is commonly used in decorative borders, garden pathways, and rockeries. | |||||||||||||||||||||||||||

| Technology description including background system | Tarmac’s limestone is a naturally occurring aggregate sourced from quarries across the UK. It is extracted through controlled excavation or blasting, depending on the geology of the site. Once quarried, the limestone is transported to processing facilities where it is crushed, screened, and graded into various sizes to ensure consistency and quality. This process produces a clean, durable material with excellent drainage properties and a light, uniform appearance. | |||||||||||||||||||||||||||
