Method & Evidence

AimWhat is the optimal composition of hydraulic binders to maximize the water resistance and mechanical performance of recycled road bases utilizing foamed bitumen technology?
MethodExperimental design and material testing
ProcedureRecycled road base materials were processed using cold deep recycling technology with foamed bitumen and various hydraulic binders. Different binder compositions were formulated based on a simplex-centroid experimental design. The water resistance was evaluated using the tensile strength ratio (TSR), and indirect tensile modulus (IT-CY) was also measured.
