“…The optimum use of plastic can be 10% and 15% of bitumen based on Marshal Stability test (K. Sandhiya, 2018). Performance of roads depends highly on the quality of its components, especially the type and quality of the bitumen and aggregate properties since it determines the most important properties of the asphalt mix (Toth, 2015) . Methods used to attain a higher performance road are duly by improving the quality of bitumen which is done by modifying the rheological properties of bitumen by blending it with various products such as plastics and rubber (Vasudevan, 2006).…”

The amount of waste plastics which are released by factories and human activities day to day becomes big problem to human being health as days ahead. The major impact of waste plastics is the environmental pollution, as they do not decompose. This current study, was about to use those waste plastics as Partial replacement of bitumen in bituminous concrete production for road pavement. Different materials like plastics, coarse aggregate, fine aggregate, filler materials and bitumen were used. The plastics used in this research were shredded into small pieces of 5 to 10 mm size and mixed with aggregates in hot state. Tests on aggregates and bitumen for strength and specific gravity were carried out respectively. To examine the behavior of plastics, test specimens were prepared without plastic contents with different bitumen percentage of 4.5%, 5%, 5.5%, 6%, 6.5% for the purpose of finding optimum bitumen binder for normal mix. The optimum bitumen percent for normal bituminous mix is 5.7% and the maximum stability of 9.2875 KN is reported, which is above 8.2 KN as minimum stability accepted. The quantity of bitumen was partially replaced with 3%, 10%, 15% and 20% by plastics. High stability value of 10.89 KN was found at optimum 14.3% plastics. This paper reports that waste plastics produce a good result compare to normal mix.

“…This type of pellets designed for HMA wearing courses of heavy traffic load roads, improving pavement performance through superior binder property. It improves stiffness of the mix while somewhat improving low temperature behaviour as well [4]. Reclaimed asphalt pavement (RAP) material is the output of milling of bituminous layers during pavement rehabilitation.…”

Stone mastic asphalt (SMA) is a gap graded mix which is categorised by more quantity of coarse aggregate, high asphalt content and fibre. Due to stone on stone contact and presences of high filler content, it acts as a stiff matrix and reduces the rutting due to heavy traffic load. This research presents a study on fatigue performance RAP replaced SMA mixes using VG 30 as binder along with elastomer as a modifier and results were compared with conventional SMA mix. The specimens prepared were tested using several laboratory test procedures: Marshall mix design, indirect tensile strength, moisture susceptibility, drain down test and Repeated load fatigue test. Test results showed Marshall Properties of the RAP mix improved up to a RAP content of 30% without elastomer modifier and RAP content up to 60% with elastomeric modifier. From the moisture susceptibility test results, the elastomeric modified SMA mix showed high resistance to moisture damage when compared to conventional mix and 30% RAP replacement mix. Repeated load fatigue test was conducted for different stress load and temperature and results showed elastomeric modified SMA mix offered high resistance to deformation across all stress level and temperature when compared to conventional and optimum RAP mix. As a fatigue loading increased resulted in decrease of number of fatigue cycles and increased in the initial tensile strain of the mix. As the percentage of RAP addition increased the initial tensile strain decreased.

“…Miscellaneous fiber types, such as glass, carbon, polyester and those of aramid origin, have high strength and stiffness and can be used for the modification of asphalt pavements. Some properties of hot mix asphalts, which are stiffness, resistance against low temperature and plastic deformation behavior, can be enhanced via cellulose fiber and elastomeric chemicals containing special additives [7]. Despite improved performance characteristics, increasing economic and environmental requirements in today's conditions have led researchers to develop new fiber materials.…”

Stone Mastic Asphalt (SMA) is a mixture design against rutting caused by intensive and heavy traffic loads. While modified bitumen needs to be used in this mixture, the use of cellulosic fibers is essential to prevent the infiltration of bitumen during the carriage of mixture due to high bitumen content. In this study, the effects of basalt fiber on the performance of SMA mixtures is investigated as an alternative to cellulosic fiber admixtures in the prevention of draindown. Raw materials commonly used in Turkey were chosen as Type-I graded limestone aggregate and B50/70 asphalt cement, according to the General Directorate of Highways. In total, 109 specimens were prepared by a gyratory compactor according to the superpave design method. Sixty of these specimens were basalt fiber added samples with a ratio from 0.1 % to 0.8 % by dry weight aggregate. An addition of basalt fiber of 0.6 % at 25 °C seriously increases the resilient modulus and tensile strength of the samples. In addition, 0.4 % basalt fiber mixed samples shows that the greatest resistance against permanent deformation according to the results of static uniaxial creep test performed at 40 °C. Basalt fibers have no positive effect when a decrement of bitumen viscosity exceeds the bitumen softening point at the end of repeated uniaxial tests. On the other hand, bitumen draindown and water damage test results are within acceptable limits.
