INFLUENCE OF FILLERS ON THE CHARACTERISTICS OF THE CONSISTENCY OF BITUMINOUS MASTICS --BITUMEN, FLEXIBLE AND DURABLE. 3RD EUROBITUME SYMPOSIUM 1985, THE HAGUE, NETHERLANDS, SEPTEMBER 11-13, 1985

INFLUENCE DES FILLERS SUR LES CHARACTERISTIQUES DE LA CONSISTANCE DES MASTICS BITUMINEUX

This work was carried out within the framework of the development of a mix design method for dense bituminous mixes. The introduction points to the important influence of the filler-bitumen mix on the properties of bituminous road mixes. It shows the need of proportioning the constituents in order to manufacture mixes containing mastics with uniform consistency. A laboratory test programme has been carried out on 32 different fillers in order to show up the parameters which are controlling the mastic's consistency. The viscosity and the increase of the ring and ball softening point were measured on these fillers for different filler/bitumen ratios. The results obtained may be interpreted on the basis of multi-linear correlations in which the most significant parameters are: (1) the filler/bitumen ratio or the filler concentration of the mastic. (2) the voids content of the filler. These results are confirming studies out in other laboratories and allow the design of the mastic as a function of the consistency. This proportioning method was then applied to make 26 dense bituminous mixes containing 26 different fillers (all other conditons remaining unchanged). The mechanical behaviour of these mixes was then studied by means of a mechanical test. The obtained results show that the adopted design method leads to satisfactory materials but that the mechanical performances are not strictly identical.
