- compositions Ci and C 2 according to the present invention have viscosities at 150 ° C lower than oxidized bitumens B ox i, B ox2 and B 0X 3 and composition C3 Soprema.
- the compositions according to the invention are sufficiently manageable at low temperature to be applied at temperatures of the order of 160.degree. C., thus reducing the energy consumption and the residence time. application of the bonding binder and thus of the coating process.
- composition Ci has a TBA and a penetrability P25 equivalent to those of the oxidized base B ox i.
- composition C 2 has a TBA and a penetrability P25 equivalent to those of the oxidized base B ox2 .
- the values of the torque TBA and P25 penetrability make it possible to evaluate the consistency of bitumens and bituminous compositions as well as their resistance to deformation.
- the higher the TBA and the lower the penetrability the more the bituminous composition has a good consistency and a high resistance to deformation.
- bituminous compositions according to the present invention have a consistency equivalent to oxidized bitumens of the prior art while allowing application at a lower temperature than that of oxidized bitumens.
- the creep test is performed as follows. A mass of 0.5 kg of each sample of bonding binder is hot cast in a scrap mold and then demolded cold. The loaves thus obtained are placed in incubators at different temperatures and under a load of 2.5 kg (+/- 50 g) to simulate the stacking of the loaves on each other, during their transport. Indeed, 6 loaves are generally stacked vertically on a pallet during the transport of the bitumen rolls. The blocks are first placed in an oven at a temperature of 40 ° C. If no creep is observed after a certain time, at most after 15 days, new loaves are molded and placed at a higher oven temperature. This operation is repeated until a significant creep of the loaves is observed. Creep results in deformation of the loaves and flow of the bituminous composition. The thus deformed loaves are unusable as bonding binder. The creep evaluation is performed qualitatively visually.
- ** np irrelevant; the bonding binder has not been tested since creep is observed at lower temperatures.
- the principle of the test consists in exerting traction on a sample consisting of two identical strips of sealing membrane bonded together by the bonding binder to be tested. Each band has an initial length of 15 cm.
- the assembly of the two strips is done by casting at 160 ° C a layer 1 to 2 mm thick bonding binder on one side of one of the membrane strips. Then the two strips are associated and held thus joined until cooling of the bonding binder to form the sample to be tested. Only one end of the two strips of the sample is not glued over a length of about 4 cm.
- the peel test is carried out using a traction machine marketed by Zwick and equipped with a thermal chamber to perform the test at 23 ° C.
- Each unglued portion of the end of the sample is held by a jaw of the pulling machine.
- the initial distance between the two jaws is 50 mm.
- the angle of tension between the two membranes of the sample, initially at 90 ° will open gradually as the traction is performed at a speed of 100 mm / min. Under stress, the sample membranes lengthen until the bonding binder gives way and the membranes peel off or until at least one of the membranes breaks.
- the pulling machine measures the average stress applied to the sample (T m0 y eim e), the maximum spacing distance of the two jaws before detachment of the two membranes in percentage with respect to the initial distance between the two jaws (D max ), and the energy supplied to reach this maximum distance of separation (E max ).
- T m0 y eim e the average stress applied to the sample
- D max the maximum spacing distance of the two jaws before detachment of the two membranes in percentage with respect to the initial distance between the two jaws
- E max the energy supplied to reach this maximum distance of separation
- bituminous compositions C 1 and C 2 according to the present invention are particularly effective as bonding binder compared with oxidized bitumens.
- the results of the peel test show that the maximum stress x max , the distance D m a x and the energy E max are significantly higher than those of the bonding binders B ox2 and
- bituminous composition C3 comprising a polystyrene-b-poly (ethylene-butylene) -b-polystyrene polymer (SEBS)
- bituminous compositions C 1 and C 2 give values of maximum stress x max and energy E max significantly higher, for an equivalent value of D max .
- bituminous compositions according to the present invention are particularly remarkable in that they are more effective as bonding binder than bonding binders of the prior art, especially compared to oxidized bitumens and bitumens modified with elastomers. They are also easy to implement. They have a very good fluidity at a temperature of 150 ° C., which makes it possible to use them as bonding binder at an application temperature of less than 190 ° C., preferably less than 180 ° C., more preferably less than or equal to 160 ° C.
- the recommended application temperature of the oxidized bitumens is generally from about 220 ° C. to 250 ° C. At this temperature, the energy consumed is important and the heating time is long.
- the application temperature of the recommended bonding agent C3 is from 190 ° C. to 200 ° C. At this temperature, the problems of energy consumption and heating time are still problematic.
