Bituminous compositions

Priority: June 12, 1962 / France Registration number, 900 439

The present invention relates to bituminous compositions welohe, for example, for covering pipes, Pipelines, connecting lines and the like can be used can. The invention also relates to a method for covering objects such as pipes, pipelines and connecting lines by means of the new bituminous compositions.

Bituminous compositions suitable for the above Above mentioned purpose can be used, are already known. For certain purposes of application, however, the quality must be of the coated objects are so perfect that the compositions heretofore available therefor are generally not are satisfactory. This is particularly true when the bituminous compositions are intended for covering pipes are, Wilohe for the production of supply systems (Pipeline) to be used for gas and oil, which immediately naoh

must be sunk into the 3rd.

such applications must the Obereugt yarn have different types of mechanical sigma sticks »They should be hard to avoid damage from existing building sides and unevenness, for example on the floor of the square, la which The drill must be relocated without resistance and at the same time must be sufficiently flexible so that no SiS or Rupture occurs when the pipes or lines change their direction » Finally, such coatings also have to withstand an impact resist, so that stones and other · appropriate materials, which during the filling of the trench on the coated Lines fall, the coating does not peel off, or cracking · In addition, the coatings should retain a certain consistency even at the highest temperatures, see above that no flow occurs.

In addition to these mechanical characteristics, which are required of the finished coatings, it is necessary that the bituminous composition used for the coating purposes has very special properties «Their viscosity at high temperatures should be low, so that can be applied at the lowest possible temperatures, while at the same time at medium and normal temperatures should be sufficiently hard.

Pie previously known bituminous compositions do not unite in themselves all these desired characteristics,

The present invention is accordingly a bituminous composition, «oak the very sharp and even contradicting «requirements mentioned above is equivalent to*

3s it has now been found that bituminous compositions, which are particularly good at covering for example Pipes, pipelines and connecting lines are suitable, must have the following composition:

50 to 75% by weight of a blown bitumen, 5 to 20% by weight of a coal tar pitch and 15 to 40% by weight of a filler.

The blown bitumen can be of any kind and for example from a bitumen from Venezuela or from the Middle East. Sin blown Bitumen has a three-point softening point using the ring and ball method in the range between 80 ° and 150 ° and in particular in Range of 85 ° to 135 ° is particularly preferred · In some In some cases it can be advantageous to use two or more different types of bitumen in the same mixture In this case, preferably at least one of the types of bitumen is used a softening point (ring and ball) in the range given above

Any coal tar pitch can be used in the novel compositions of the present invention, for example a low temperature coal tar pitch. Preferably However, a coal tar pitch with a softening point in

Mixture No. 4 also shows the disadvantage that it cannot be used at temperatures below 200 °

Coatings can only be made using mixtures No. 2 and 3 produce whose properties are satisfactory in every respect and which can also be applied at temperatures below 200.

Example 2

With two further compositions according to the invention, tests were carried out as in the previous one Example have been described. For comparison purposes, tests were also carried out with coatings made from only one of the Ila main components of the compositions carried out.
