“…According to Hofko et al [20] the spectrum analysis derived from FTIR, multiple classes of molecular limits can be easily identified by the wavelength of the absorption spectrum clearly defined by the characteristic band maxima. Studies by Yu et al [21] as in Figure 3, at 813cm-1m modified bamboo fibers (BF) containing melamine-formaldehyde exhibit a unique feature. This is due to the N-containing heterocyclic ring out of the bending vibration -N = C-H [22].…”

“…journal.ump.edu.my/construction ◄ Figure 3. Spectrum analysis of bamboo fibers [21] Mubaraki [18] studied the amount of asphalt binder using ASA polymer and Al2O3 nanomaterials in asphalt mixture and found that 4% can considered as optimum percentage of modifier for both types. Despite their greatest points, the FTIR spectra of ASA polymer and Al2O3-altered asphalt binders remained identical, indicating that no structural changes occurred in the altered binders connected with the conventional asphalt binder.…”

A Review of Morphological and Chemical Properties of Porous Asphalt

2021

View full text Add to dashboard Cite

Porous asphalt mixture is also known as gap graded mixture with less amount of fine aggregate has led the mixture contains high air voids, tends to make the mixture less durable and high porousity. Hence, past researchers has investigate on how to increase the strength of porous asphalt mixture by the addition of additive such as fiber and nanomaterials. The chemical and physical properties of porous asphalt mixture was highlighted in this paper to compare its structure, the bonding between the materials and its chemical composition that exist. This paper reviews on how additive affect the asphalt mixture in terms of Scanning Electron Microscopy (SEM), X-Ray Diffractions (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). These tests are selected to improve the asphalt mixture according to the morphological and chemical properties of porous asphalt. This study is expected to identify the morphological and chemical composition of the materials in asphalt mixture.

“…As a result, researchers have studied the modification of BF and other natural fibers to facilitate their use in composite materials. [ 7 ] For example, Yu et al [ 9 ] used melamine‐formaldehyde copolymer to modify BF, and covalent bonds were formed between the amino group on the copolymer and the hydroxyl group of the BF, resulting in a strong adhesion between the modified BF and the asphalt matrix and improving the tensile strength of the asphalt mixture. Liu et al [ 10 ] treated corn stover fibers with silane to remove some of the hemicellulose and lignin from the fibers and to enhance the crystallinity and crystallite size of the fibers, which greatly improved the tensile strength of the fibers.…”

This study resolves the poor enhancement problem of high‐temperature performance and lower dissolution of styrene‐butadiene‐styrene (SBS) modified asphalt and soybean bio‐asphalt (SBA) (extracted from waste soybean oil) by tannic acid (TA) modified bamboo fiber (MBF). The rheological properties and microscopic morphologies of the modified asphalt and fibers were investigated by dynamic shear rheometer (DSR), multiple stress creep recovery (MSCR) tests, and Fourier transform infrared (FTIR) spectroscopy. The results showed that the rutting factor and deformation recovery rate of 3% MBF/3% SBS/SBA modified asphalt at 64°C increased by 78.4% and 31.99% as compared with those of 5% SBS modified asphalt. Further, the phenolic hydroxyl group of TA reacted with C═O groups in SBA to form a strong connection between BF and bio‐asphalt. Fluorescence microscopy analysis revealed that SBS solubilization and BF formed a uniform and stable network structure in the modified asphalt. This study provides a useful, greener, and cost‐effective strategy for the effective utilization of industrial waste (BF and waste soybean oil) by converting into advanced functional materials for highway and construction industries novel and hence can concomitantly decrease environmental pollution and enhance energy conservations.

“…It was determined from Marshall mix design calculations that bamboo fiber content should be 0.2–0.3% for dense grade asphalt (DG) and 0.4% for stone matrix asphalt (SMA) [ 24 ]. Yu et al found that bamboo fiber incorporation improved the stability and tensile strength of the asphalt mixture, and SEM images revealed a strong bond between the fiber modified asphalt mixture and the asphalt binder [ 25 ].…”

Reinforcement Effect of Different Fibers on Asphalt Mastic

2022

Fiber materials as an asphalt mixture additive and stabilizer can effectively improve the performance index of asphalt pavement. In this study, lignin and carbon fiber were used as modifiers to study their effects on the road performance of asphalt mastic. Based on the frequency sweep, linear amplitude sweep (LAS) and multi-stress creep recovery (MSCR) experiments were conducted to test the high-temperature rutting and medium-temperature fatigue resistance of asphalt mastic with different fiber incorporation and low-temperature performance tests based on bending beam rheometer (BBR). The results indicate that adding fibers increased the stiffness of the asphalt mastic, and the modification effect of lignin fibers was better than that of carbon fibers. Meanwhile, the characteristic flow index of the asphalt mastic gradually increased with the increase in temperature, indicating that it gradually became a near-Newtonian fluid at higher temperatures. The addition of fibers also improved the high temperature rutting resistance of the asphalt mastic but did not have an advantageous effect on fatigue and low temperature cracking resistance. Additionally, the fitting results of the four-parameter Burgers model show that the use of fiber modification decreases the proportion of elasticity and viscous creep compliance but increases the delayed elasticity part.
