Energy consumption and material production are two major factors associated with the road construction industry. Worldwide, millions of tons of hot mix asphalt production consume a huge amount of fuel as an energy source in terms of quantity and cost to achieve the standard temperature of up to 170 °C during the mixing process. Modification of bitumen can not only reduce its usage but also the consumption of energy (fuel) during the asphalt mix production process at low temperatures. This study provides a method to save energy by proposing the addition of bitumen modifier in the road construction sector. Furthermore, to make it compatible with the field conditions for road construction, stability analysis is executed on the prepared samples by partially replacing the bitumen with polyurethane foam (PUF) and plastic waste (PW) (at 10%, 20%, 30%, 40%, and 50%). Experimental results demonstrate a reasonable saving in the amount of energy (33%) and material (40% bitumen) used and showed that similar strength of developed asphalt mix can be achieved using PUF. An extensive calculation concludes that these savings could make a huge difference in construction economics of mega road infrastructure projects, especially during an energy crisis.

Low-temperature cracking is one of the major pavement distresses in cold regions. To reduce the prevalence of such cracks, crumb rubber modified asphalt (CRMA) has been applied for a long time. However, CRMA experiences compatibility and segregation problems with asphalt. Silicone oil has long been seen to improve compatibility and segregation problems of polymers in asphalt, but its benefits on low temperature performance of crumb rubber asphalt have not been explored. Furthermore, silicone oil can be obtained as virgin or recycled from industrial transformers; however, the recycled silicone oil’s influence on low-temperature crack performance of asphalt has also not been explored. Therefore, the purpose of this study was to investigate the effect of recycled silicone oil (SO) on dispersion and low-temperature fracture performance of crumb rubber asphalt. The fracture mechanics-based single-edge notch beam (SENB) test was performed at temperatures of −12°C, −18°C, and −24°C. In addition, fluorescence microscopy (FM), atomic force microscopy (AFM), and Fourier-transform infrared (FTIR) experiments were also conducted. Results show that the addition of SO to CRMA increases displacement, fracture energy, and fracture toughness at low temperature while it decreases stiffness which reduces cracking. In addition, AFM results show that surface roughness increases with the addition of SO which indicates that bonding of asphalt and rubber particles had also improved. FM also confirmed that dispersion of rubber particles had improved with addition of silicone oil. FTIR results revealed that asphalt samples with SO treatment were hydrophobic which potentially repels water ingress and delays the freezing of asphalt. Lastly, statistical analysis revealed that the influence of silicone oil on low-temperature performance of rubber asphalt was significant. Therefore, the study concluded that fracture cracking resistance is improved by addition of silicone oil to crumb rubber asphalt.

“…Compared to the "wet" process, the reaction time in the "dry" process is considerably shorter due to larger size of rubber crumb particles [14]. Numerous, mostly foreign, researchers have studied the ways in which asphalt properties are affected by rubber [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Tai Nguyen and Nhan Tran [15] have confirmed that asphalt with rubber produced by the "dry" process can be used in flexible pavements to improve rutting properties.…”

“…According to testing presented in [25] the degree of degradation of crumb rubber affects its dispersion and interaction with the modified elastomeric bitumen, which positively influences production of modified bitumen. Sri Wulandary and Tajandra [26] have established that addition of rubber increases the quality of asphalt mixture, and allows the use of lower bitumen content in asphalt mixture when waste tire is added as modifier [26].…”

Asphalt pavement surface course with recycled rubberAfter the end of their use in road traffic, car tires can be used in road construction as an addition to bitumen mixtures. By adding recycled rubber, bitumen properties are improved and better behaviour of placed asphalt is achieved (lower sensitivity to water action and cracking, and good skid resistance). Results obtained on three asphalt-pavement test sections, with and without addition of rubber in bitumen, are analysed after eleven years of road use. Characteristics of asphalt with different proportions of recycled rubber in bitumen and polymer modified bitumen are analysed. Key words: recycled rubber, bituminous mixture, indirect tensile strength of asphalt Prethodno priopćenje Miroslav Šimun, Sandra Mihalinac Završni sloj asfaltnoga kolnika s dodatkom reciklirane gumeNakon što se prestanu upotrebljavati za prometovanje po kolnicima, umjesto da se odlažu na odlagalište otpada automobilske se gume, mogu koristiti u cestogradnji kao dodatak bitumenskoj mješavini. Dodavanjem reciklirane gume poboljšavaju se svojstava bitumena te se postižu bolja eksploatacijska svojstva asfalta (manja osjetljivost na djelovanje vode i pojavu pukotina te dobre hvatljivosti vozne površine). Nakon jedanaest godina eksploatacije analizirani su rezultati na trima pokusnim dionicama asfaltnoga kolnika s dodatkom gume u bitumenu i bez njega. Analizirana su svojstva asfalta s različitim udjelom reciklirane gume u cestograđevnome i polimerom modificiranome bitumenu. Ključne riječi: reciklirana guma, bitumenska mješavina, indirektna vlačna čvrstoća asfalta Vorherige Mitteilung Miroslav Šimun, Sandra Mihalinac Deckschicht der Asphaltfahrbahn mit recyceltem Gummi Nachdem Autoreifen nicht mehr für den Straßenverkehr verwendet werden, können sie im Straßenbau als Zusatz zur bituminösen Mischung verwendet werden, anstatt auf einer Mülldeponie entsorgt zu werden. Der Zusatz von recyceltem Gummi verbessert die Eigenschaften von Bitumen und es werden bessere Nutzungseigenschaften von Asphalt (geringere Anfälligkeit für Wasser und Risse und gute Griffigkeit der befahrbaren Oberfläche) erzielt. Nach elfjähriger Nutzung wurden die Ergebnisse der drei Teststrecken für Asphaltfahrbahnen mit und ohne Gummizusatz im Bitumen analysiert. Die Eigenschaften des Asphalts mit unterschiedlichen Gehalten an recyceltem Gummi im Straßenbau und im polymermodifizierten Bitumen wurden analysiert.
