Bitunova in Europe

Laboratory control:

"Bitunova Ukraine" has its own modern laboratory, which is accredited in the UKRMETR TESTSTANDART system. Due to this we have the possibility to carry out any kind of laboratory tests – testing of the input components, function control during the production process and examination of the end-product’s characteristics. Furthermore, on the basis of laboratory test the selection of production process characteristic can be adapted according to features of the input components. Because of this, the whole production process can be monitored. This is the basis for the high quality of our products.

Our laboratory administers a data bank listing all characteristics of the input products. As a result, we can analyze and influence the quality of the goods we use. For example, we can use chippings with the following characteristics due to the careful, on laboratory testing based, selection of chippings suppliers
  • no cubic form stone materials content < 7%;
  • loamy and dusty content <0,65%.

Only because of our modern laboratory, we are able to exceed the Ukrainian official "stability in storage index" by three times.

Tests that can be done in our laboratory:
1. Road bituminous emulsions (SSU B V.2.7-129:2013, technical conditions):
  • determination of the emulsion’s optical appearance,
  • determination of the concentration of hydrogen ions,
  • determination of the emulsion homogeneity,
  • determination of bitumen and emulsifier content,
  • determination of the relative viscosity,
  • determination of the storage stability,
  • determination of the transport stability,
  • determination of the adhesion characteristics of the adhesion promoter,
  • determination of the miscibility of the emulsion with chippings,
  • determination of the dissociation index,
  • determination of the physical-mathematical features of the remaining adhesion promoter after evaporation of water from the emulsion.

2. Oil Bituminous (SSU 4044-2001, technical conditions):
  • determination of the penetration,
  • determination of the relative viscosity,
  • determination of the softening temperature,
  • determination of mass change after heating treatment,
  • determination of residual penetration change,
  • determination of penetration index.

3. Rock material (SSU 2.7-71-98 chippings and gravel for construction work):
  • determination of the grain size distribution,
  • determination of the grain content,
  • determination of the cold resistance,
  • determination of the loamy and dusty content,
  • determination of water-clayey rock and amiesite (gravel),
  • determination of the dampness.

4. Asphaltic concreted mixture (ÖNORM EN 12697-1/A1 Asphalt. Prüfverfahren für Heißasphalt.)
  • extraction of cold mixtures,
  • extraction of hot mixtures,
  • extraction of polymerically modified mixtures.

Our laboratory staff, as well as any other employees, constantly improves their specific knowledge in professional courses.
