“…Numerous studies were conducted to evaluate the viscoelastic function using different materials for modification, such as styrene-butadiene-styrene (SBS), natural rubber latex (NR), and epoxidized natural rubber (ENR). All these MACs show equivalent and slight increase in G* values at low frequency and temperatures, as well as more strongly increased G* at high frequency and temperatures, which represents an improvement in terms of the temperature susceptibility [31,42].…”

“…From the result, the performance of the concrete mixtures improve when used 5% of HDPE by weight in asphalt blend. Then, Yu Kuang et al, did a researched with two main objective, first is to evaluate on behaviour of Evotherm-J1 and M1 as additive in compaction technology and second objective is to study the effect of Evotherm-J1 and M1as additive in moisture anti strip [6]. The study carried by Diefenderfer et al (2008), using sasobit as an additive in asphalt with two different mixtures in the study.…”

Abstract. This study aims to evaluate the fatigue performance of modified asphalt mixture using Indirect Tensile Fatigue Test. Titanium Dioxide (TiO2) powder in a form of rutile was used for producing asphalt concrete with lower mixing and compaction temperature compared to conventional hot mix asphalt without reducing its physical and mechanical also resistance to fatigue. The characteristic of the asphalt and modified asphalt was evaluated using penetration test, softening test and rotational viscosity test. Titanium dioxide of 2%, 4%, 6%, 8% and 10% by weight of asphalt has been incorporated into unaged 80/100 asphalt mix in order to improvise its performance and to fulfill the objectives of this experimental study. As a result, TiO2 as an additive is potential to decrease the penetration and increasing the softening point of the asphalt. In terms of fatigue performance testing, addition TiO2 additive does help in improving the fatigue properties as it shows greater result than the control asphalt. In conclusion, TiO2 is great in improving fatigue properties.

“…In some cases, crumb rubber is difficult to disperse throughout the bitumen due to the rubbers have been used in a vulcanized state. Ineffective dispersion requires high temperatures and long mixing times and can yield a heterogeneous binder [15]. Rubber dispersion, nevertheless, can be improved by using chemical solvent (e.g.…”

“…Basically, crumb rubber contains of natural rubber which helps to improve the elasticity behaviour; carbon black and synthetic rubber which are able to improve the thermal stability of the modified binder [15]. Ongoing research and practices demonstrated that crumb rubber can be effectively incorporated into road surfacing [16].…”

Abstract. Road surface is designed to be the durable surface material to sustain the traffic loading. However, due to physical and mechanical stress, pavement deterioration is accelerated. Thus, modifying conventional bitumen by improving its properties is seen as the best method to prolong pavement in-service life. The purpose of this paper is to study the effect of waste natural rubber (NR) latex on rheological properties of bitumen. Conventional bitumen PEN 80/100 was modified with different content of waste NR latex using a high shear mixer at temperature of 150°C. The modified binder properties were characterized by conducting physical test (i.e. softening point, penetration and penetration index) and rheological test (i.e. dynamic shear rheometer, DSR). Results showed that, the addition of waste NR latex improved the rheology properties, which indicates by improving of rutting factor (G*/sin δ). This properties improvement has also shows a potential to resist deformation on road surface despite of high traffic loading.
