The kind b »w. the properties of the invention are greater Bitumen foods vary depending on the type and the properties of the bitumen used as the starting material and the coal used, de «mixing ratio these components and depending on «whether further additives and solvents are present, strong * The various bitumen compositions according to the invention can be liquid to semi-solid. Generally wise however, the bitumen compositions according to the invention in comparison to conventional bitumen compounds for road paving material, the bitumen (asphalt), cuttings or cold asphalt and Tar contain the following excellent properties:

1) The Bituraon masses of the invention are extraordinary little heat sensitive and perform even when exposed to direct sunlight in summer are, kmun for the pavement to flow. Your preparability is superior at higher temperatures *

2) The bitumen compositions of the invention have a high resistance to cold weather and do not become brittle even at lower temperatures.

3) The bitumen compounds of the invention have an excellent one Adhesion and high adhesive strength to natural aggregates, such as split, clover or Sand and against calcined artificial aggregates such as slag, Synopearl and Luacobite as well as against cement-concrete products ·

5) The bitusia sauces according to the invention have no Newton ' see fluids corresponding flow maintenance and also have an exhausted * viscoelasticity « can «on by applying tone pressure a high. Detention * are able to achieve a high level of adhesive strength. Finally, the flowers of the invention have a Superior Vasserfeetigkelt, resistance to weathering and chemical moisture

Tables III and IV below show the properties of the inventive sweet bitumen maaaaen determined by Teeto compared to those found in the same tests Properties of conventional bitumen neasan or road surface materials listed.

From Tables III and IV it is important to know Properties, such as extreme sensitivity, resistance to cold weather, Sticky eyes and solvent evacuation (Klebefeatigkelt) the following can be seen:

i) Heat sensitivity: this property results from the values of the Pliess test, the penetration and the softening point *

ii) Kaitwettorfactigkoit: the behavior in this regard eich results from the values dee "Fraafi-Brechpuakta", the penetration and the softening point.

iii) Adhesion: the property arises from the Values dea Löaungateata and de · Harshall-Stabilitütateete.

iv) Solvent volatilization (adhesive strength):

Bitumen compounds or road paving compounds are occasionally used to reduce the viscosity of the Hasse and a consequent improvement in kneadability. Can be processed by diluting in some cases blended with a volatile solvent. Regarding this It should be noted that in terms of solvent evaporation between conventional blending asphalts, which contain no coal grains and bitumen lakes according to the invention, which are microfine '» granular charcoal onthalton consists of a great difference, dom out a great difference in the Glue © eti & keit results in * Uu the «su untermauorn, were performed the following tones:

In each case, JOO g samples of the mixtures (, B, C and D, the composition of which can be seen in Table I) are placed in a flask and then subjected to a distillation temperature in accordance with ASTM-D402-55 up to an extraction temperature of 260 ° C The results obtained are listed in Table II. As can be seen from Table II, the amount of distillate in the bitumen _{composition according to the invention (sample A) 1} lifts the microfine-grain cabbage.
