Effect of bitumen origin on behavior of cold recycled mixes using foamed bitumen technique
Original language description
Within the European research project COREPASOL supported by a group of countries associated in the Conference of European Directors of Roads, the effect of distilled bitumen gained from different locations on the characteristics (indirect tensile strength, water susceptibility and stiffness) of cold recycled asphalt mixtures has been assessed as a partial task. In the first step, the optimum foaming water was evaluated for each bituminous sample by optimizing the relationship between the expansion rateand the half-time. For the optimized foaming water content, one cold recycled mix design with different foamed bituminous binders has been used. The behavior of all experimental mixes has been tested by indirect tensile strength test done after 7 and 14days for cured specimens, whereas the curing procedure respected Czech technical specification TP208. In parallel, stiffness testing has been done for each mix variant and a group of specimens has been water soaked between 7th and 14th da
