laboratory test

Department of technology of road works and laboratory testing of materials (accreditation certificate №BY / 112 02.2.0.1167) performs tests of building materials on the basis of contracts.

 

 

Since 2012, construction laboratory is accredited for testing of bitumen to meet the requirements of STB EN 12591-2010 in terms of:
