“…It is noted that the typical simplification for repeated moving tire load is to use cyclic plate loads [29], in which the cyclic load time is equivalent to the load duration (time of passing the imprint at certain speed multiplied by the load cycles). However, according to the previous study, compared with moving load with equivalent load magnitude and number of cycles, much lower permanent deformations are observed in the cyclic plate loads due to the shear stress reversal [30,31]. It is resulting from the direction principal stresses rotate and shear stress reversals (tension to compression or vice versa).…”

The rapid development of industrialization, urbanization, and population of the society augments the rising amount of municipal solid waste (MSW). With the advantage of considerably reducing mass and volume of solid wastes and generating energy, the incineration is a widely used treatment method for MSW. During the incineration process, the organic substances contained in the wastes are combusted, and the massive residues are remained. Of the incineration residues, bottom ash takes up to 80–90%, and the remainders are fly ash along with air pollution control residues. Dealing with the municipal solid waste incineration (MSWI) bottom ash in a sustainable manner is the primary principle. Significantly, MSWI bottom ash has been successfully utilized in diverse beneficial applications in recent decades, especially in civil engineering applications. This paper investigates the mechanical properties and validity of MSWI bottom ash as applicable substitutes of conventional subgrade materials. For this reason, a series of direct shear and CBR tests are performed on specimens with different water contents and dry densities.

“…For example, the harvested energy could be used for [141]. To understand the mechanical properties of energy harvesters and permeable pavements at multiple spatial scales, advanced testing and characterization methods could be used to evaluate the expected service life and identify the best timing for regular maintenance [142][143][144][145][146][147][148]. From the economic point of view, we should also assess the life-cycle cost-benefit of green technology applications.…”

A wide range of literature on predominant green technologies for sustainable pavements is summarized in this paper. It covers two major aspects: energy harvesting technologies and permeable pavement systems. Fundamental mechanics of energy harvesting techniques and possible designs of energy harvesters are described, with the evaluation of energy conversion efficiency, and advantages and disadvantages. In addition, the designs of permeable pavement systems are discussed, along with their advantages and disadvantages. The latest technical innovations are highlighted. It is found that green technologies are promising for developing more sustainable pavements. Application issues are also pointed out, including construction challenges, durability, and life-cycle cost-benefit assessment. Future research directions are suggested to address practical challenges, such as efficient design, construction challenge, timely maintenance, and life-cycle performance assessment.

“…Yapıları ve yapı elemanlarını korumak adına kullanılabilen harçlar, yapıların servis ömrünü önemli derecede etkileyen ve çok yaygın olarak kullanılan yapı malzemelerinden birisidir (Huang et al 2018). Bu nedenden dolayı günümüze kadar geçen süre içerisinde inşa edilen yapıların mevcut ortam koşullarından zarar görmemesi adına sıva uygulamaları yapılmıştır.…”

“…Bahsedilen bilgilerin yanında şu ana kadar yapılan çalışmalarda, harç üretiminde kullanılan kumun granülometrik bileşiminin harç reolojisi üzerine etkisinin incelendiği (Stolz and Masuero 2018) ve harç kalınlığının eğilmede çekme dayanımına etkisinin incelendiği (Huang et al 2018) araştırmalar bulunmaktadır. Harçların sülfatlı ortamlardaki davranışları ile ilgili bazı çalışmalar yapılmış olup yapılan çalışmalardan birinde lif katkılı çimento harçları % 5 NaSO4 çözeltisine 4 ve 8 ay süre ile maruz bırakılmıştır ve bu ortama maruz kalan örneklerde ağırlık kaybı gözlenmiştir (Wongprachum et al 2018).…”

In this study, lime-gypsum-cement composite materials were produced in which fixed cement amount was used (40%) and gypsum and lime materials were used in varying proportions. Produced composite materials were exposed to sulphate solutions and investigated how they were affected by these environments. In the mixtures prepared for the production of the samples; CL 80-S calcium lime, satin plaster and CEM II/B-M (P-LL) 32.5 R type cement were used. Samples placed in the moulds were kept in laboratory for 2 days, and then samples taken from the moulds. After that, these samples were exposed to water curing for 7 days. 2.5% and 5% MgSO4 and Na2SO4 solutions were used for aggressive media tests of the produced composite materials. Samples which were cured in 7 days water were kept in the related solutions until 90 days of age. As a result, the composite materials were less affected by the Na2SO4 effect, however, the compressive strength of the samples exposed to Na2SO4 solution was 8.8-12.2 MPa and It was determined that the compressive strength of the samples exposed to MgSO4 solution varied between 4.1 and 9.1 MPa. In the case of composite materials which have been exposed to MgSO4 effect, a better compressive strength value is obtained from the samples according to the reference samples when 30% lime is used.
