Thermal suspectability analysis of the reuse of fly ash from cellulose industry as contribution filler in bituminous mixtures

Abstract

The increased population has accelerated pavement deterioration of and boosted production of residues, generating a constant environmental problem. One of the main problems of pavements is a failure to develop union between bituminous mastic ligand and aggregate. The following study evaluates the use of ash from cellulose incineration as a contribution filler to improve thermal susceptibility of pavements in different climatic zones. The applied methodology for dosage was based on volumetric criteria and state curves. The obtained results showed that reusing this residue in determined conditions (Cv/Cs 1) offers lower wear loss to 35% of temperatures between 10 and 60 C, due to the Cv/Cs = 0.75 ratio that maximizes the cohesive properties of the mixture. Therefore, we showed that this type of industry residue can be reused without complication in zones of certain climatic criteria and that it provides improved properties to the asphalt mix compared to conventional mixes.

Analysis of Greenhouse Gas Emissions and the Environmental Impact of the Production of Asphalt Mixes Modified with Recycled Materials

“…Cellulose ashes are classified as an industrial by-product and come from the process of burning wood debarking and chipping for energy generation, due to the high-pressure steam generated in biomass boilers [36]. These ashes are currently disposed of in authorised industrial solid waste (ISW) landfills.…”

The Relationship between Poisson’s Ratio Index and Deformation Behavior of Asphalt Mixtures Tested through an Optical Fiber Bragg Grating Strain Sensor

“…In respect to material performance improvement, many scholars have tried to introduce new materials into the mixture design to comprehensively improve the high temperature performance of asphalt mixtures [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. However, precise evaluation methods and indicative indices are still needed to reflect the development of permanent deformation within asphalt pavement under high temperature and complex loading conditions to further improve and predict the performance and stability of an asphalt mixture.…”

Damage Fracture Characterization of Asphalt Mixtures Considering Freeze–Thaw Cycling and Aging Effects Based on Acoustic Emission Monitoring

“…Amani et al [21] discussed the influence of different long-term aging levels (3, 5, 7 and 9 days) upon the recovery process of a self-healing asphalt mixture, and concluded that the healing efficiency of the asphalt mixture gradually decreased as the aging time increased. Additionally, some research has been conducted on the aging and temperature effects of different additives on asphalt mixture, such as fly ash [22], basalt fiber and diatomite [23], and copper slag [24].…”
