Testing

Testing

The usual general testing systematic for asphalt construction methods is also applicable to the Stone Mastic Asphalt construction method and is consists of

• Mix design testing

• Internal control testing

• Check testing.

The special focus here lies in the mix design tests.

Uses worldwide

The advantages of Stone Mastic Asphalt have led to worldwide recognition - SMA is being used on every continent. This provides practical experience specific to each country in which SMA is used. This experience allows for specially created SMA formulas which are based on the local conditions.

We have here a few examples from various countries. We have also cited the valid technical specifications for the location.

Surface properties of Stone Mastic Asphalt

The driver of a car is exclusively interested in the impact of the surface properties on the road. He or she expects a high level of driving comfort and safety from the road surface. These expectations call for a whole series of requirements regarding the surface properties.

Long term reliability of Stone Mastic Asphalt wearing courses

At the end of the 1980's and start of the 1990's, more than 20 years after the paving of the first Stone Mastic Asphalt-wearing courses or rather, its predecessor, there was no doubt that Stone Mastic Asphalt was an excellent, long-lasting useful construction method - almost all wearing courses paved in the early days, were excellent even under extreme traffic demands.
