“…The small differences in the values for consistency, setting times, density, water-absorption and compressive strength was accounted for due to the difference in fineness. PABA produced more fines than PAB because of the temperature the bones were subjected to during the ashing process [17].…”

Global warming, improper solid waste and environment degradations are the major challenges facing humankind. One way to lower the effect global warming is to use less energy intensive materials optimally in construction and proper solid waste disposals to protect the environment from it harmful effects. In this study, the mechanical properties of Pulverized Animal Bone (PAB) and Pulverized Animal Bone Ash (PABA) as cement replacement in concrete were examined and the mechanical properties of concrete containing PAB/PABA optimised using response surfaces methodology (RSM). Central composite Design (CCD) method of experimental design of RSM was used to design the experiment using the key variables in the mechanical properties of Pulverised Animals Bone Ash concrete (PABC) and Pulverised Animals Bone Concrete Ash (PABAC). The variables considered in the model’s development are Bone powders percentages replacement of cement in concrete at five levels (5, 10, 15, 20 and 25% levels) and curing age (3, 7, 28, 60 and 90-days). The Test conducted on fresh PABC/BAPAC was slump test while on hardened concrete were, Density, water absorption and compressive strength tests. Analysis of variance (ANOVA) indicates that the variables PAB/PABA and curing age influence the variability in the generated models and all the models are statistically significant at 95% level in all the factors levels. Numerical method of optimisation was applied to determine optimum mix proportions for PABC/PABAC. The optimum mix for PABC was obtained by addition of 5.00% PAB after curing for 42.24-days with 0.736 desirability. In PABAC, 5.00% PABA and 44.87-days curing with desirability 0.736 was the optimum.

“…Al-hasan et al [ 4 ] used recycled coarse aggregate and polymer to prepare environmentally friendly pavement, which effectively improved the durability of asphalt pavement. Kadhim et al [ 5 ] used animal ashes in different proportions to replace limestone to prepare asphalt mixture. It was found that when 20% animal ashes were used to replace limestone, the mechanical properties of the asphalt mixture were improved, so as to improve the durability.…”

Acid erosion can accelerate the process of early damage of asphalt pavement and decrease the durability of asphalt pavement. However, there are limited research results for asphalt mixtures that can resist acid rain erosion. To systematically evaluate the impact and action law of acid rain erosion on the durability of asphalt mixtures, three gradation schemes were used: periodic dry–wet cycle immersion test, contact angle test and road performance test. The acid rain erosion resistance of epoxy asphalt mixture, SBS-modified asphalt mixture and 70# matrix asphalt mixture were tested from three aspects of anti-aging performance, freeze–thaw cycle performance and fatigue performance. The results show that the erosion of acid rain can significantly decrease the adhesion between asphalt and aggregate, and affects the road performance of the asphalt mixture. Acid rain erosion can significantly decrease the mechanical properties, adhesion and durability of asphalt mixtures. Epoxy asphalt has better physical properties, adhesion and acid rain erosion resistance than 70# matrix asphalt and SBS-modified asphalt. Epoxy asphalt has excellent adhesion due to its polar group, high cohesion and thermosetting resin with low shrinkage, which can effectively resist moisture erosion, spalling and temperature stress cracking, thereby effectively resisting the erosion of acid rain. Epoxy asphalt mixture has the strongest acid rain erosion resistance, which can be further enhanced when used together with waste rubber powder and modified bamboo fiber. On the whole, asphalt mixture with high-density structure and thicker asphalt film can effectively resist acid rain erosion. The durability of asphalt concrete (AC)-type gradation mixture and stone mastic asphalt (SMA)-type gradation mixture are equivalent, and both are superior to open-graded friction courses (OGFC)-type gradation mixture. The gradation of asphalt mixtures and the type of asphalt binder have great influence on their acid rain erosion resistance and durability. In order to realize the directional control of the acid rain erosion resistance and durability of different asphalt mixtures, a multi-parameter comprehensive assessment indicator system between the type and property of asphalt, the gradation of asphalt mixture, and the acid rain resistance and durability of the mixture need to be established in the future.

The durability of pavement subgrade materials is the most important indicator for judging their merits as well as their mechanical properties. The durability of pavement subgrade material is mainly reflected in its water stability, because in the actual pavement environment, the subgrade is subjected to the infiltration of groundwater, immersion and the washout of pressure water under the concrete slab. The subgrade is subjected to a series of damage caused by freeze-thaw cycles and wet-dry cycles due to changes in temperature. In view of this, this chapter has targeted. In view of this, this chapter focuses on the frost resistance, water stability, scour resistance, dry shrinkage and sulfate erosion resistance of iron tailings as pavement base material. The study is carried out to simulate the real situation as much as possible to provide more detailed and accurate guidance for the actual engineering application. The study will provide more detailed and accurate guidance for the actual engineering application.
