Opis:
The fine-grained waste mineral materials is used in the recycling technology with foamy bitumen as mineral filler from 5% to 20% in the aggregate mix. This allows its use of mix recycling, fine-grained waste mineral materials from the dedusting system of aggregate in coating plant and during the production of aggregates in mines (whilst crushing the rocks and rinsing the aggregate). In this investigation three different fine-grained waste mineral materials (dolomite, gabbro, and quartzite sandstone) were tested the basic functional properties were defined i.e. pH – acidity – alkalinity, Blaine’s actual area Pw, the contents of clay minerals – with the use of methylene blue indicator MBF and determination of the voids of dry compacted filler. The fine-grained waste mineral materials are in proportion of 10%, 15% and 20% to mineral mix. From the analysis, which was within the domain of stability and flow (Marshall), indirect tensile stretch (ITS) and water resistance (TSR), the dependency of functional properties of fine-grained waste mineral materials on the mechanical basecourse properties in recycling technology with foamy bitumen was defined. The possibility of utilization of fine-grained waste mineral materials in the recycling technology of deep cold with foamed bitumen, substantially affect the protection of the environment. At the same time it preserves the required properties of recycled pavement.

Opis:
Knowledge of the fatigue life is required to properly predict pavement structure reliability with respect to the number of loading cycles. The possibility of using foamed bitumen and bitumen emulsion as binders in the composition of road bases makes it necessary to identify the influence of the binder type on the service life of these layers through dynamic tests. Obtaining proper physical and mechanical parameters does not necessarily ensure the correct evaluation of the recycled base quality. Satisfaction of the quality-related requirements does not guarantee the provision of the required fatigue life parameters. Cold recycled bases with cement should work within the viscoelastic range due to hydraulic bonding in the structure. If this range is exceeded, a considerable rise in strains occurs as a result of brittle fracture, leading to the loss of fatigue life. The paper presents the results from the fatigue tests of recycled bases. The amount of bitumen used in both cases was 3% and 5%. For the production of the bitumen emulsion and foamed bitumen, 70/100 pen bitumen was used. Portland cement I 32,5R was applied as a binder. The binder comprised 3% of the mineral composition of the recycled base layer. Fatigue tests were performed in compliance with the requirements of enclosure E of PN-EN 12697-24 at a constant normal stress of 250 kPa, 375 kPa and 500 kPa. The results were used to compare the effects of the binder type applied to the recycled base and determine the service life in terms of the stress applied.
