“…Therefore, the fastening between the aggregates decreased and causes lower Marshall stability of asphalt mixtures. The above results are consistent with the results obtained by other investigations described in [ 31 , 32 , 33 , 35 ]. In addition, the stiffness and adhesion strength of mastic is an important factor in resistance against low temperature cracking due to bitumen oxidation, fatigue cracking, and the appearance of lower resistance on rutting.…”

“…Testing the possible application of two types of BA, from rice husks and date seeds, as the filler in hot asphalt mixtures was conducted by Tahami et al [ 33 ]. The content of each type of BA in asphalt mixtures was 0% (the control mixture with the standard filler), 25%, 50%, 75%, and 100%.…”

“…Various applications of this type of ash were the most and longest researched. With time, the possible application of other types of ash were researched, such as ash from municipal waste incineration plants [27,28], from paper mills [29], and bio ash of various origins [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Compared to the properties of ash from the combustion of coal, the properties of BA have a much wider range, and it is often necessary to carry out certain preliminary actions to meet the requirements of a particular application set by technical specifications.…”

Today, the road construction profession is more than ever facing limited and increasingly expensive resources for component materials of asphalt mixtures, which has also led to the need for continuous research on the use of waste materials. One such potentially usable waste material is ash obtained by the combustion of wood biomass that is used to produce heat and electricity. The goal of this paper is to ascertain the possibility of using wood ash (WA) as the filler in asphalt concrete mixtures for the base-wearing layers of a pavement. The properties of Marshall stability (MS), quotient (MQ) and deformations, and the indirect tensile strength of water-conditioned samples and dry samples were tested on asphalt samples of an AC16 surf mixture with different contents of wood ash as the filler. The obtained values of MS and MQ indicate that a 50% content of bio ash in the filler results in an increase in asphalt’s resistance to the appearance of plastic deformations and greater tensile strength and in good asphalt resistance to the action of water.

“…Overall, the Marshall stability, stiffness, and rutting performance of asphalt mixtures were enhanced under the application of RHA and DSA. Furthermore, compared with the control mixture, HMA incorporated with RHA and DSA exhibited a particularly improved fatigue resistance, which means that the fatigue life of the resulting concrete will be longer with agro-wastes [67]. While comparing 2% cement as a conventional filler when preparing asphalt, the different proportions of RHA (2% to 4%) as an alternative filler were found to be better than a mineral filler by lowering the optimum bitumen amount in an asphalt concrete mix [68].…”

Concrete, as the world’s most implemented construction material, is increasingly being used because of the rapid development of industrialization and urbanization. Limited resources and progressive depravation of the environment are forcing scientific efforts to seek alternative and effective materials from large amounts of natural resources as additives in the partial replacement of cement. Cement is a main constituent of concrete. To solve and minimize environmental issues, research works attempting to employ the wide availability of agricultural wastes, such as sugar cane bagasse, rice husk, sugar cane straw, and palm oil fuel, among others, into cement, and to finally bring sustainable and environmentally friendly properties to concrete are being examined. Agro-waste materials are crushed into fine and coarse aggregates or are burnt into ash, and are then mixed with cement, which is known as agro-cement. The replacement of aggregates, either partially or fully, is also deemed as a sustainable material in construction. This paper mainly reviews the current research on agro-cement that has been researched and applied for the enhancement of the strength and durability of concrete. It further summarizes the relevant knowledge and techniques, while providing optimal parameters for applying agricultural wastes in concrete.

“…Depending on its characteristics, ash can be utilised as a filler, as a replacement for small aggregate fractions, as a binder itself when it contains active minerals (e.g., lime, calcium and magnesium silicate or alumina silicates), resulting in hydraulic binding, or as a binder supplement or addition when it contains pozzolanic minerals (e.g., glass, Portland, gypsum or clay minerals), which in combination with other materials leads to a pozzolanic reaction [3]. For wearing course construction, biomass ash has been investigated for both asphalt [4,5,6] and concrete [7,8] pavements. However, for both pavement systems, a good quality subgrade is of high importance.…”

Feasibility of Agricultural Biomass Fly Ash Usage for Soil Stabilisation of Road Works

et al. 2019

Agricultural biomass ash is a waste material produced by incineration of residue from fields after harvesting crops. The use of agricultural biomass in industry produces large quantities of ash that represent an ecological problem. Another ecological problem is the dependency of road building on natural materials, which has been traditionally used for all pavement layers. Today, roads are built on less accessible and suitable terrains, increasing the need for improving the mechanical characteristics of locally available materials by various means of stabilisation. Within this research, three agricultural biomass fly ashes are used as lime substitutes for hydraulically stabilised soil. The purpose of this research is evaluation of potential use of agricultural biomass fly ash for the soil stabilisation of road works, i.e., for embankment and subgrade purposes. The results indicate that there is a potential of using barley, sunflower seed shells and wheat fly ash as lime substitutes in the soil stabilisation of road works. The strength characteristics of stabilised soil incorporating biomass fly ash are highly dependent on its chemical composition. Using a three-dimensional digital image correlation technique, it is concluded that the elastic properties of stabilised soil correlate to a fracture mechanism that can be efficiently defined by this modern research tool.
