Tests of asphalt mixtures and road surfaces

We carry out MMA tests in the following areas:

• MMA temperature measurement according to PN-EN 12697-13: 2017-12
• Determination of the soluble binder content (extraction) according to PN-EN 12697-1: 2020-08
• Grain determination according to PN-EN 12697-2 + A1: 2019-12
• Density determination according to PN-EN 12697-5: 2019-01
• Determination of the bulk density of asphalt samples according to PN-EN 12697-6: 2020-07
• Determination of the free space content in asphalt samples according to PN-EN 12697-8: 2019-01
• Mastic asphalt penetration test according to PN-EN 12697-20: 2020-07
• Determination of water sensitivity of bituminous-asphalt samples (ITSR) according to PN-EN 12697-12: 2018-08

The tests of road surface finish include:

• Sampling cores from the layer according to PN-EN 12697-27: 2017-07
• Determination of the layer compaction index according to PN-EN 13108-20: 2016-07
• Determination of the free space content in a layer according to PN-EN 12697-8: 2019-01
• Determination of the thickness of asphalt road surfaces according to PN-EN 12697-36: 2005
• Determination of shear strength of layer joints according to the Instructions for Laboratory Testing of Interlayer Adhesion of Asphalt Layers according to the Leutner Method.

We also conduct research on component materials for the production of asphalt mixtures:

• Bitumen penetration according to PN-EN 1426: 2015-08
• Determination of asphalt softening point by the ring and ball method according to PN-EN 1427: 2015-08
• Binder flow test according to PN-EN 12697-18: 2017-07, point 5
• Filler quality tests, according toPN-EN 933-9 + A1: 2013-07and PN-EN 933-10: 2009;
• Test of the suitability of aggregates for bituminous mixtures and surface treatments according to PN-EN 13043: 2004.
