Fatigue behaviour of asphalt concrete beams reinforced by glass fibre-reinforced plastics

Intermediate Temperature Fracture Resistance of Stone Matrix Asphalt Containing Untreated Recycled Concrete Aggregate

“…With respect to aggregate replacement in the area of asphalt concrete, there have been numerous studies involving the partial or complete replacement of traditional natural aggregates with materials such as recycled concrete, brick, glass, ceramic, rubber, recycled asphalt and steel slag (Ge et al, 2014;Medina et al, 2015;Ameli et al, 2020;Kim and Na, 2021;Pourtahmasb and Karim, 2014). Continuous research into the use of construction waste as recycled aggregates in various types of projects, including bituminous applications, should be conducted (Silva et al, 2019).…”

Fatigue Performance of Double-Layered Asphalt Concrete Beams Reinforced with New Type of Geocomposites

“…In contrast, Zieliński used a slightly more simplified three-point bending (3PB-PR) test scheme with controlled stress mode [17] and conducted the test at two temperatures of +18 and −2 • C. According to his results, nonwoven polyester geofabric used as a reinforcing layer had almost no effect on fatigue life, while the influence of polyester geocomposite and glass grid geocomposite combined with polyester nonwoven geofabric was significant. However, even with these materials, the positive effects of reinforcement were visible only at the temperature of +18 • C. Ge et al [18] investigated the behaviour of asphalt concrete beams reinforced with glass fibre-reinforced plastics (GFRP) using the 4PB-PR test and noticed that the application of such a reinforcing layer can extend fatigue life by almost 9 times, which would be especially useful for obtaining durable pavements on steel bridge decks. According to Zofka et al [19], who conducted both 4PB-PR fatigue and monotonic 3PB tests using the specially developed advanced material characteriser, geogrid reinforcement is particularly effective in retarding crack propagation after the initial crack in the bottom layer has occurred.…”

A multi-criteria decision-making analysis for the selection of fibres aimed at reinforcing asphalt concrete mixtures

“…In order to reduce road failures and to increase their durability, engineers and scientists are constantly searching for new mechanisms or additives to improve the mechanical performance of asphalt mixtures (Fitzgerald 2000, Sibal et al 2000, Xiang Ma, Qiang Li 2018. In this regard, fibers have proved to provide additional tensile strength and strain energy to the mixture when it is subjected to fracture and fatigue processes by traffic loads (MAHREZ et al 2005, Ge et al 2014, Yoo and Al-Qadi 2014. Similarly, several studies have reported the benefits of adding fibers to AC mixes as well as the relevant improvements in terms of tensile strength, moisture susceptibility, ductility, rutting resistance and fatigue properties (Cleven 2000, Fu et al 2000, Moghaddam et al 2014, Yin and Wu 2018.…”
