Bitumen modifiers for reduced temperature asphalts: a comparative analysis between three polymeric and non-polymeric additives
Cuadri Vega, Antonio Abad
; Carrera Páez, Virginia; Izquierdo Rodríguez, María Ángeles; García Morales, Moisés; Navarro Domínguez, Francisco Javier (Elsevier, 2014)
This study presents three bitumen modifiers which may find successful application in the fabrication of binders for warm mix asphalt in the paving industry. In that sense, two non-polymeric additives, thiourea and thiourea ... -
The development of polyurethane modified bitumen emulsions for cold mix applications
Carrera Páez, Virginia; Cuadri Vega, Antonio Abad; García Morales, Moisés; Partal López, Pedro (Springer Verlag, 2015)
Bitumen emulsions stand for an alternative paving practice to the traditional hot-mix asphalts. In addition, modified bitumen emulsions show a better performance than unmodified ones. This work studies the feasibility of ... -
Hybrid Rubberised Bitumen from Reactive and Non-Reactive Ethylene Copolymers
Senise, Simona; Carrera Páez, Virginia; Cuadri Vega, Antonio Abad; Navarro Domínguez, Francisco Javier; Partal López, Pedro (MDPI, 2019-11)
Hybrid modification is a relatively new concept of incorporating two or more polymeric modifiers of different nature to a bitumen, in order to take advantage of their complementary features. Aiming to this, in this paper, ... -
Influence of the prepolymer molecular weight and free isocyanate content on the rheology of polyurethane modified bitumens
Carrera Páez, Virginia; Cuadri Vega, Antonio Abad; García Morales, Moisés; Partal López, Pedro (Elsevier, 2014)
Isocyanate-based modification is lately gaining acceptance as a successful way to give added value to bitumen, a crude oil refining by-product. In order to study the influence of prepolymer type on the rheological properties ... -
Modification of binder with tyre rubber and polymeric networks for usage in road asphalt mixes
(Universidad de Huelva, 2020)Hybrid modification is a relatively new concept of incorporating two or more polymeric modifiers of different nature to a bitumen, in order to take advantage of their complementary features. However, the problem of its ...
