The paper presents results obtained on the basis of tests carried out using the innovative hydraulic binder intended for a recycled base layer with foamed bitumen.The tested hydraulic binder consisted of three components: cement,hydrated lime and fines.The analysis includes: final time of mortar setting,volume change in mortar,compressive strength after 7 and 28 days of curing,bending strength after 7 and 28 days of curing.The analysis relied in identifying optimal compositions of innovative binder components in terms of its suitability for pavement recycled base layer.Optimisations considered obtaining a two variant such as: quick-setting and a normal-setting hydraulic binder.The analysis of test results indicate that there are solutions for binder compositions that meet the requirements for normal-setting of hydraulically bound base layer in recycled technology.In the scope of obtaining a quick-setting binder,at least 80% of cement binder in the innovative hydraulic binder composition is required.
