Abstract:

Crumb rubber modification has been proven to enhance the properties of pure bitumen. This paper looks at some of the international standards for producing crumb rubber modified bitumen (CRMB) and reviews the effect of crumb rubber to the rheology of crumb rubber modified bitumen. The review shows that the rheology of CRMB depends on internal factors such as crumb rubber quantity, particle size, and pure bitumen composition, and external factors such as the mixing time, temperature, and also the modification technique. These factors govern the swelling process of crumb rubber particles that lea

Abstract:

Rheological model for crumb rubber modified bitumen (CRMB) by the rheological testing and model analyzer was investigated in this paper. The effects of crumb rubber content and temperature on rheological model and viscoelasticity of CRMB were conducted. The results illustrate that rheological model of bitumen is transformed from Dashpot into Burgers at 60°C after bitumen has been modified by crumb rubber. And the elasticity of CRMB is increased and the viscosity is decreased with crumb rubber content rising. For the modified bitumen with 20% crumb rubber (CRMB-20), its rheological model is Bur

Crumb rubber-modified bitumen (CRMB) has been utilized in the asphalt paving industry for decades due to its various benefits.

To systematically explore the non-Newtonian behaviors of CRMB, a dynamic shear rheometer was utilized to apply shear loading on the samples at various temperatures and shear rates.

Aside from the fact that it reduces the amount of tyre waste, the use of crumb rubber can also improve the properties of bitumen, which can help to extend the life of flexible pavements. When VG 30 bitumen is combined with crumb rubber, penetration values drop significantly. As the modifier concentration is increased, the penetration value decreases. When modified with 5CR, 10CR, and 15CR, neat bitumen’s penetration value drops to 61, 58, and 49 respectively. Mars

Abstract:

This paper considers the effect of aging processes on viscoelastic characteristics of vacuum residue oxidation products modified with crumb rubber. Viscoelastic properties were compared to original bitumen raw material-vacuum residue and vacuum residue oxidation products during short-term and long-term aging. The complex shear modulus of the vacuum residue and its oxidation products decreased with an increase in temperature. Short-term aging resulted in increased shear modulus for all samples.The vacuum residue oxidation product modified with crumb rubber had the maximum values of the rutting

Abstract:

Researchers are increasingly concerned about the vast amounts of waste rubber tires produced globally, which contribute significantly to environmental pollution. The potential of incorporating waste rubber tires to modify bitumen has garnered considerable interest. This study assesses pavement design temperatures according to SUPERPAVE standards for representative Malaysian regions. The assessment is based on hourly air temperature data and simulates temperature diffusion in typical Malaysian road pavements using the finite difference method (FDM).

Abstract:

ABSTRACT The pressure aging vessel (PAV) protocol is adopted worldwide for quality control on any bitumen available. However, crumb rubber-modified binders (CRMB) produced by wet technology are nonhomogeneous materials in which rubber particles are dispersed into the bituminous matrix, and the interaction between the two constituents can be triggered at any time by increasing temperature. It is assumed that the PAV temperature is insufficient to trigger such interaction. This assumption has never been verified. If proven otherwise, any rheological measurement performed on the PAV-aged rubberiz

Abstract:

Different modification methods, such as adding modifiers and pretreating crumb rubber, have been developed to achieve decent engineering properties and reduce the viscosity of rubberized bitumen. This study evaluated the influence of the modification methods on the aging resistance for rubberized bitumen. Two types of crumb rubber—a 40-mesh crumb rubber and a microwave-pretreated crumb rubber—and two kinds of modifiers—Sasobit and Trans-polyoctenamer—were selected to prepare rubberized bitumen. The samples were subjected to a Thin-Film Oven Test for the simulation of the short-term aging condi

Asphalt polymer has superior characteristics than conventional asphalt. Styrene Butadiene Styrene (SBS) is a polymer that has proven its performance in heavy traffic, but it must be imported and expensive. Crumb rubber have high potential to be used as an asphalt modifier. Asphalt modified crumb rubber has high viscosity and is not homogeneous, so that the utilization cannot be delayed. This reduces workability in the field. This study aims to obtain asphalt modified crumb rubber which is easier to use by adding materials that do not affect its performance.

Abstract:

The actual problem of the oil refining industry is to improve the process of oxidation of heavy oil residues and the properties of oil bitumen. One way to solve the problem is to add modifiers. The addition of modifiers leads to an intensification of the oxidation process and an increase in the characteristics of the bituminous binders. The work aims to study the effect of adding rubber crumb on the process of vacuum residue oxidation and the properties of the obtained rubber-bitumen binders (RBB).

The process of modifying road bitumen obtained from the residues of Ukrainian oils processing with rubber crumb has been studied. The dependence of the softening temperature, ductility, penetration, and elasticity of the three-component bituminous composition “bitumen : linseed oil : rubber crumb” on its formulation has been examined. Based on the mentioned composition a new type of cold-applied bitumen roofing has been developed. A process flow diagram for the production of modified bitumen and special-purpose bituminous composition has been developed.

The granular sub-ballast in conventional ballasted trackbed structure, though cheap and easy to construct, requires frequent maintenance, and cannot protect the subgrade against water infiltration. However, asphaltic sub-ballast in asphalt-ballast trackbed can reduce stress on the subgrade and provide a waterproofing layer against water infiltration. Asphalt binder is however, susceptible to temperature fluctuations. The aim of this study therefore is to investigate whether the addition of crumb rubber to asphalt binder could reduce the susceptibility of asphalt to temperature, and thus, impro

Bitumen is one of the most important materials used in roads. During asphalt pavement construction, workers can be affected by emissions, such as volatile organic compounds (VOCs), when bitumen is heated. Therefore, it is crucial to correctly identify and measure VOCs. This paper presents a novel, promising method to determine VOC emissions. The proposed method offers a way to standardize routine measurements on a lab scale, enabling reliable comparison across bitumen types and their modifications or additives.

Abstract: In India majority of roads are being constructed by flexible pavements. But the performance of the pavement largely depends on quality and type of materials used, Construction methodology adopted, temperature, climatic conditions etc. Because of these variations in the mentioned parameters, pavements undergo distress/ failure. The different types of failure in flexible pavement are Rutting, Shovelling, Edge breaks, Cracks, Slippage etc. Rutting is a common phenomenon which occurs in flexible pavement surface due to overloading of vehicles and repeated application of wheel load.
