Available in 6mm and 10mm grades, this angular buff quartzite delivers excellent skid resistance and lasting durability, making it ideal for medium-traffic areas such as estate roads, rural highways, access lanes, and residential developments.

With a Polished Stone Value (PSV) of 53, Heritage Quartz provides dependable resistance to polishing under traffic, ensuring ongoing surface grip. Its MoHS hardness of 8 and Aggregate Abrasion Value (AAV) of 1.6 reflect its toughness and wear resistance, while a Los Angeles (LA) value of 23 confirms its strength under heavy loading.

Heritage Quartz is trusted by asphalt contractors and specifiers for both new construction and resurfacing projects where both appearance and performance are critical.
