Cold in-place stabilization with foamed bitumen: rehabilitation works in the re...
Correia, Eugénia Conceição da Neves Silva; Oliveira, Joel R. M.; Silva, Hugo M. R. D.; Pragosa, Joana; Martins, Anabela; Almeida, Rafael; Carvalho, JoãoThe present case study refers to the rehabilitation work in the Regional Road ER361 between Amiais de Cima and Alcanena, Portugal, using an in-place cold recycling solution with foamed bitumen. From a circular economy perspective, this solution allowed to make full use of the construction and demolition wastes (CDW) generally produced in this type of works. Two factors significantly impact the environment due t...
A pavement full-depth reclamation case study using cold in situ recycling with ...
Oliveira, Joel R. M.; Silva, Hugo M. R. D.; Martins, Anabela; Correia, Eugénia; Pragosa, Joana; Mendes, PedroThis study aims to assess the full-depth reclamation of a distressed pavement using in situ recycling with foamed bitumen. It is not widely used due to the need for specific equipment not always available. However, it presents several advantages compared to emulsion or cement-based recycling solutions. It can be open to traffic more rapidly and does not present shrinkage problems. Thus, constructing a pavement ...
Caso de estudo de reciclagem a frio in situ com betume-espuma
Silva, Hugo M. R. D.; Oliveira, Joel R. M.; Martins, Anabela; Correia, Eugénia; Pragosa, Joana; Mendes, PedroO presente caso de estudo pretende avaliar as vantagens e desvantagens da reciclagem a frio com betume-espuma, em profundidade, num pavimento muito degradado. Em Portugal, esta tecnologia tem sido pouco utilizada pela necessidade de equipamento específico, embora possa ser uma alternativa à reciclagem com emulsão ou cimento. A redução do tempo de abertura ao tráfego e do tempo de cura e a eliminação de problema...
