Bestone®

The combination of surface roughness, hardness and homogeneity makes Bestone® an excellent and qualified aggregate to fulfill current needs in road construction.

• The microstructure of the sandstone ensures a permanent high level of stone surface roughness (PSV>60) which increases road safety.
• In Europe there is a development towards an increased focus on Product Life Cycles (PLC) of roads. This means that contractors have a long-term responsibility for road surface performance. Bestone®´s constant and homogeneous quality, combined with its high resistance to fragmentation increases the durability of asphalt.
• Noise reduction is an increasingly important issue in densely populated areas. The properties mentioned previously combined with Bestone®´s cubic particle shapecontribute significantly to noise reduction by asphalt.

Besides the intrinsic properties of the stone, the unique and durable production process offers a substantial CO2 advantage.

Scottish granite
Besides Bestone®, Scottish granite is the ulyimate supplement for subsurface asphalt layers or concrete road construction. Scottish granite is a homogeneous natural stone with a 100% crushed surface. Its cubic particle shape ensures perfect workability.
