Optimization of the road binder used in the base layer in the road construction

摘要: Abstract The research focused on the application of mixed binder system to hydraulically bound mixes used in road base (HBM). This paper presents outcome tests for mechanical characteristics HBM terms type used. Seven binders were prepared a laboratory by blending three primary constituents: Portland cement CEM I 32,5R, fluidised bed combustion fly ash and kiln dust (CKD). proportions selected according experimental design. percent amount mixture was 6%. Two types aggregate as mineral material base. composition mixtures designed based Proctor method. influence properties evaluated determining compressive strength at 7, 14, 28 42 days curing, frost resistance water absorption. test results optimise with respect establish recommended composition.
