When you purchase aggregate from Royal Star Crusher LLC, you are buying more than just crushed stone — you are buying confidence. Our products comply with both BSI (British Standards Institution) and ASTM (American Society for Testing and Materials) international standards, two of the most rigorous benchmarks in the construction materials industry.

BSI and ASTM standards govern everything from particle size distribution and shape to strength, durability, and resistance to wear. Meeting these standards is not a simple task — it requires precise control over every stage of the production process, from how the rock is blasted in the quarry to how it is shaped by the VSI crusher at the final stage.

The cubical shape of our aggregate, achieved through our Metso Barmac VSI, is a critical property that affects how concrete and asphalt behave under load. Cubical particles interlock more effectively than flat or elongated ones, producing stronger, more durable mixes that last longer in roads, bridges, and buildings.

Regular testing is carried out on samples from our stockpiles. Parameters such as flakiness index, elongation index, Los Angeles abrasion value, and water absorption are measured and compared against the allowable limits defined by BSI and ASTM. Only material that passes these tests leaves our facility.

Compliance with international standards also opens doors to major infrastructure projects that require certified materials. By investing in quality from the ground up, we position ourselves as a reliable partner for engineers, contractors, and developers who cannot afford to compromise on the materials they build with.
