“…It was to determine the feasibility of utilizing the local Malaysian industrial and by-products wastes such as steel slag, ceramic waste, coal fly ash, limestone, and rejected ceramic raw material as mineral fillers [4]. Research by others showed how strength of additives named Chained Interlocked Plastic Beads (CIPB) can positively reduce fatigue and rutting in Stone Mastic Asphalt (SMA) mixtures [5].…”

Transverse cracking is a prevalent problem that occurs in asphalt pavement binders in cold climates and diminishes the integrity of the road as well as shortens the life span of the road leading to premature failure. Current specification for testing petroleum asphalt binders for transverse and low temperature cracking is not elaborate enough to accurately model the engineering behaviour of the binders. Besides, neat asphalt derived from petroleum crude oil does not seem to perform well at certain low temperatures without some modification to it. Thus, a study was to be undertaken to determine the low temperature behaviour of 60-70 penetration neat binder modified with traditionally used materials such as Crushed Lime Stone Powder (CLP), Hydrated Lime (HL) and Cellulose Oil Palm Fiber (COPF) at temperatures 0 °C,-5 °C and-10 °C. The study was carried using the state of the art Bending Beam Rheometer (BBR) to assess the stiffness value, m-value and deflection level. The tests were performed in accordance with AASHTO T 313-12 specification. The results of the penetration, rotational viscosity and softening point showed that all of the modified binder specimens are within the required range. However, the performance assessments on the modified petroleum binders with additive materials showed a varied nature with CL powder being the best and the COPF the lowest. It was also observed that the crushed lime stone powder had an increase in stiffness, reduction in deflection and m-value.

“…Because of the complexity of the pavement damage phenomenon, using proper additives and modifiers is considered the most cost-effective technique for prolong the pavement service life [8]. The modification of asphalt binder with polymeric materials and rubber powder is among the most common methods to improve the performance of the asphalt binder against most types of distresses [9,10,11]. The other method for prolonging the pavement service life is the addition of alternative environmental friendly materials.…”

Viscoelasticity property of bitumen is closely related to the service life of bituminous pavement. This paper evaluated the impact of one of the most efficient and widely used nanomaterials in various industries called hydrophobic nanosilica on the viscoelasticity property of bitumen and asphalt mixture. In this paper, three hydrophobic nanosilica modified bitumens and asphalt mixtures were researched by conventional physical properties test, SEM test, FTIR test, DSC test, DSR test, static creep test and dynamic creep test. The results showed that the introduction of hydrophobic nanosilica could strengthen the viscosity of asphalt more effectively and had better dispersion than hydrophilic nanosilica in asphalt. From conventional physical properties test and rheological performance test, hydrophobic nanosilica could weaken the temperature susceptibility of bitumen observably. From DSR test, hydrophobic nanosilica modified asphalt had a lower sensitivity and dependence on temperature and frequency than hydrophilic nanosilica modified asphalt. The Cole–Cole diagrams indicated that hydrophobic nanosilica exhibited good compatibility with asphalt compared with hydrophilic nanosilica. Newly formed chemical bonds were found in the hydrophobic nanosilica modified asphalt and its mixture with stone according to SEM test, FTIR test, and DSC test, which is the biggest difference from the modification mechanism of hydrophilic nanosilica modified asphalt. Through static and dynamic creep test, it found that the addition of hydrophobic nanosilica can significantly reduce the creep strain at the same temperature.

In recent years, various studies have shown that boron-containing additives improve the rutting performance of the bituminous pavements. However, in these studies, it was stated that these additives would decrease the workability of the bitumen and increase energy required for the construction of the pavement. On the other hand, it has been shown in many studies that waxes increase the workability of the bitumen. In this study, it was aimed to obtain bitumen with high rutting resistance and workability by adding boron oxide (BO) and beeswax (BW) to bitumen. Therefore, modified bitumen was produced by adding BO and BW at different ratios to a 50/70 penetration grade base bitumen. Then, the chemical, physical, and rheological properties of modified bitumen samples were investigated by various experiments. As a result, it has been observed that BO increases the high-temperature performance and viscosity of bitumen; on the other hand, BW decreases rutting resistance and viscosity. When BO and BW were added together to the bitumen, the negative impact of BO on workability and the negative impact of BW on high temperature performance were significantly eliminated. Especially, in 1BO + 1BW and 3BO + 3BW bitumens, the high-temperature performance of the bitumen improved without decreasing the workability.
