“…The evaluation of the aging condition was important factor to analysis the materials stability [13], thus could helps to made better material preferences, predicted the wear reliability and avoided failure application of the product. Meanwhile, although the effect of aging for elastomer structure and characteristic change got many attention from researcher [14], but the effect of ultraviolet radiation to elastomer had not been established yet [15] [16]. Its well known that ultraviolets radiation as part of sun rays could break the polymer chain of the materials.…”

Rubber solid waste amount increased continuosly and caused environmental problem since it is very difficult to be naturally degraded. Therefore, the interest of using rubber waste as raw material for new rubber product is increased. Reclaimed rubber can be used as filler aditif for rubber processing. The aim of this research was to study the effect of UV aging on the rubber product as the reclaimed filler added. The mixing of the rubber and the additives used the kneader and open mill. The vulcanization process was done by hydraulic press. In this research, the reclaimed rubber addition was varied as follows: 12,5; 37,5 and 62,5 phr. The products quality differences before and after the UV aging evaluated using physical tests. The result of FTIR showed that the polymer chain were broken by ultraviolet radiation. The physical test gives result that the hardness and tensile strength decreased, but the elongation is increased after UV aging.

“…Mouillet et al (2014) emphasize the relevant effect of UV radiation on asphalt aging and cited that the UV exposure may affect the bitumen's properties of pavement upper layers more strongly than the PAV simulation in laboratory (without UV action) does. Wang et al (2016) also reported the strong dependence of the service life of polymer modified asphalt on its weather resistance.…”

The effect of short-term oxidation, evaluated by using a Rolling Thin Film Oven Test, and the effect of weathering aging on the oxidation process of hydrated lime modified asphalts were studied. Hydrated lime (HL) has been known as an additive for asphalt mixtures and is now considered as a binder additive that increases asphalt mixture durability. HL was added to the binder in contents of 5, 10, 20, and 30 wt.%. The HL modified binders were aged by using the Rolling Thin Film Oven Test and weathering tests with xenon radiation. A storage stability test by measuring the softening points of HL modified binders was performed. The Thin Layer Chromatography with Flame Ionization Detection (TLC-FID) analysis was used to determine the fractions of resins, aromatics, asphaltenes and saturates of the binders. The aging of HL modified binders was evaluated by using Fourier transform infrared spectroscopy. According to the stability test, a hydrated lime concentration value close to 20 wt.% is the critical point at which there is a risk of segregation of the asphalt binder and hydrated lime during transportation and storage. For the sample weathering aged for 250 hours, a decrease of saturated and aromatic fractions, furthermore an increase in asphaltenes were observed for all samples. Results have shown that additions of 10 wt.% of hydrated lime in asphalt binders resulted in a higher photodegradation resistance among the other asphalt mixtures considering the carbonyl index, stability test and colloidal instability test results.

“…In research conducted on three types of asphalt modifications, differences were found in their aging resistance. The results showed different aging behaviors in different types of asphalt [13]. Asphalt is a binder in the mixture,so if aging occurs, the pavement will easily crack because its flexibility decreases, while the stiffness increases, affecting the performance of the mixture.…”

The objective of this study is to replaced of petroleum bitumen with local materials such as Buton granular asphalt (BGA) was blended with petroleum bitumen in the asphalt emulsion mixture, and to analyze the effect BGA of mixtures due aging process related to the stability, flow, and indirect tensile strength. The first method given a BGA partial substitution of the asphalt emulsion content with variations BGA content, while the second method to aging carried out in an accelerated manner in the experimental laboratory, by the sample being put into an oven at 85 °C with variations in aging time of 0, 1, 2, 3, 4, and 5 days. and checking the chemical content contained in the BGA. The results and analysis indicate that BGA at a level of 10% can be used as a substitute for part of the asphalt emulsion. Strain values increase after 1 day of aging, due to the influence of bituminous in the BGA in the mixture. Furthermore, after aging for 2, 3, 4, and 5 days, the values of strain was decreased, while the value of ITS was increased, because of the influence of mineral in the BGA in the mixture.
