1. Viscoelastic Behaviour Characterization of a Gap-graded Asphalt Mixture with SBS Polymer Modified Bitumen
A characterization of the linear thermo-viscoelastic behaviour of a gap-graded bituminous mixture with SBS-polymer modified bitumen and RAP aggregates is presented in this paper. A comparison was made, in terms of their viscoelastic behaviour, between this innovative mixture and two commonly used well-graded base-course French mixtures made with pure bitumen

2. The use of thermoplastic rubber type styrene-butadiene-styrene asphalt cements oil / O emprego de borracha termoplástica tipo estireno-butadieno-estireno em cimentos asfálticos de petróleo
Este trabalho apresenta resultados o estudo de pesquisa e desenvolvimento de misturas de polímeros em cimento asfáltico de petróleo. O asfalto é um excelente material aglutinante utilizado na construção de rodovias e vias urbanas, entretanto o aumento do número de veículos comerciais e da carga transportada por eixo tem levado a deteriorização prem

3. Rheological evaluation of polymer-modified asphalt binders
Currently, the most used polymer for asphalt binder modification is the thermoplastic elastomer styrene butadiene styrene (SBS) and aromatic oil is commonly added to the mixtures to improve their compatibly. This paper proposes the use of oil shale from sedimentary rock as a compatibilizer agent for polymer-modified asphalt binder (PMB). PMBs were produced b

4. Evaluation of asphalt mixtures produced with conventional peruvian asphalt binder PEN 60/70 and SBS polymer-modified type I 60/60 and PG 76-22 / Avaliação de misturas produzidas com ligantes asfálticos peruanos convencional PEN 60/70 e modificados por polímero SBS tipo I 60/60 e PG 76-22
The main goal of this work is the evaluation of the behavior of conventional peruvian asphalt binder AC PEN 60/70 and SBS polymer-modified asphalts I 60/60 and PG 76-22, when used in hot-mix asphalt (HMA), under both conditions with and without short-term aging. It aims also to establish the asphalt binder performance grade (PG), which is based on the weathe
