Core Testing and Sampling

 

Core testing and sampling requires a core to be taken from a reinstatement, delivered to a UKAS accredited laboratory and tested for the following areas of compliance:

 

Air voids

Testing the air voids in a core shows that NRSWA legislation is being complied with and that voids are at the correct specification. The presence of water in a pavements is detremental to its life. It is vital to achieve adequate compaction to keep initial permiability low and prevent increased oxidation, water damage spalling and cracking. Low air voids may cause rutting and bleeding. Air void testing also proves that materials which are designed to be porous allow water to pass through the matrix so that drainage occurs.

 

Core depth

Measuring the depth of a core is a key part of the testing. If the reinstatement is not the correct depth, it will not be stable or durable.
