Abstract:

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: quicksetting 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.
