Investigation of Cold Recycling of Bituminous Surface Treatment with Foam Bitumen

The course of turned bituminous pavement layers into hot mix asphalt (HMA) has been increasing day by all over the world. Bituminous surface treatment that contains consirable amount aggregate and bitumen, is an important source recycling offers a great materials intead virgin material usage on consruction. In study, it was aimed to investigate usability layer in base HMA roads mixing with foam bitumen active filler order eliminate potential performance degradation will be encountered when recycled due low percentage compared wear climatic conditions traffic loads time. study conducted intends technically evaluate cold materials; for 70/100 grade, 5 different mixes were prepared ideal investigated this grade. effect mixture evaluated 50/70-100/150-160/220 grades mixtures single ratio (2.5%). It fillers give suitable results preparing three fillers; cement, hydrated lime fly ash. To these productions, ITS, unconfined compressive strenght, triaxial resilient modulus permanent deformation tests performed. obtained showed production made using 2% 1% found moisture sensitivity structural stability. Recycling cement environmentally economically beneficial method reducing both waste raw consumption.
