Influence of Waste Tire Particles on Freeze–Thaw Resistance and Impermeability Performance of Waste Tires/Sand-Based Autoclaved Aerated Concrete Composites

Waste tires/sand-based autoclaved aerated concrete (SAAC) composites were prepared by mixing waste tires, which have different particle sizes and content. The physical performance, mechanical properties, freeze–thaw resistance, impermeability performance, phase composition, and microstructure of waste tires/sand-based autoclaved aerated concrete composite materials were examined. The results demonstrated that the 750-μm-sized waste tire particles on the surface of the SAAC composite did not agglomerate. Moreover, these particles did not damage the pore structure of the composites. The SAAC composites, with a relatively high compressive strength and low mass-loss rate, were obtained when the contents of waste tire particles ranged from 1.0 to 2.5 wt.%. For composites prepared with 2.0 wt.% of 750-μm-sized waste tire particles, the optimal compressive and flexural strength values were 3.20 and 0.95 MPa, respectively. The increase in the rate of water absorption on SAAC composites was lowest (i.e., 16.3%) when the soaking time was from 24 to 120 h.

THE STUDY ON UTILIZATION WASTE TIRE SEEDS AS AMIXTURE OF AC-WC ASPHALT ON ROAD PAVEMENT

The purpose of this study are to find out the process of making AC-WC asphalt by using waste tire ore as an additives to hot mix asphalt and also to find out the general effect of waste tire ore as additives in the asphalt mixture to the characteristics of AC-WC asphalt. [2].In this study, the variation of the mixture added with tire ore starting from 0%, 3%, 6% and 8% addition of tire ore waste for the highest variation value is 3%, stability value is 494.99 kg, Voids Filled With Asphalt’s value is 68,40%, value of Voids in Mix is 3.65%, flow value is 3,21 %, value of Marshall Quotient is 154,61 kg/mm, Density’s value is 2,29 gr/cc. Finally, it was concluded that the addition of waste tire ore is not in accordance with SNI 06-2489-1991 because the higher percentage value in the mixture will decrease the value of Marshall Stability.
