## 1 Introduction
Furthermore, studies in China [29], Turkey [30], Indonesia [31], and Sri Lanka [32] can also be cited. Therefore, by-products from different sources can be used in engineering works by determining the most appropriate concrete mixture for CPBs. For more practical pavement construction, it is essential to use an appropriate design method. However, most ICBP design methods come from the adaptations of AP [7]. Then, due to the difficulties in structurally verifying pavements with CPBs, efforts were made to investigate the ICBP working mechanism, and a fair approach was reached [33]. Then, the elasticity modulus (Em) is a characteristic that should be included in the ICBP design. In Brazil and Portugal, on experimental tracks in Sao Paulo and Lisbon, respectively, the Em of the surface layer was calculated via back-analysis using the deflections provided by the Falling Weight Deflectometer (FWD) [9,34]. In the US, experimental studies were made in ICBP with FWD, observing a progressive increase in the surface layer's stiffness [35]. In urban areas, such as roads and parking areas, the land is usually covered with conventional AP, which is impervious and results in rainwater being directed to storm drains instead of the foundation through infiltration [36,37]. Furthermore, over 90% of pavements are AP in the USA [38]. Then, there are high AP surface temperatures during summer during hot periods. In addition, the increase in traffic density leads to a higher concentration of contaminants on the pavement's surface layer. A solution for these problems is the application of ICBP because of its potential for temperature reduction, stormwater management, and the retention of contaminants [38,39]. This solution positively influences the Life Cycle Assessment (LCA) to evaluate the sustainability and economic advantages of the complete structure. This paper aims to review the performance analysis of ICBP with by-products, such as coconut fibers and recycled materials from CDW, and to compare the skills with AP, especially for light-traffic urban roads applications. For this aim, the authors analyzed the studies published on the Scopus search engine (www.scopus.com, accessed on 6 May 2023) related to ICBP. This tool was used by searching in the article's title, abstract, and keywords with the following query string: (\"concrete\" AND \"paving\" AND \"blocks\") OR (\"interlocking\" AND \"pavements\"). The search provided 1125 documents from 1972 to 2022, separated into six groups: 1. mechanical behavior via mix parameters or the influence of by-products; 2. sustainability via the heat island effect (HIE) or contaminants concentrations; 3. stormwater management; 4. design procedures; 5. LCA, and 6. others. Figures 2 and 3 show the queries' outcomes by year and country, respectively. The main direct inferences were as follows. 1. Research efforts that considerably increased after 2002; 2. Stormwater management, sustainability, and LCA applied on ICBP began to have more visibility only after 2006, 2012, and 2015, respectively; 3. The US and China are the countries that have contributed the most to the number of documents on ICBP; and 4. Apart from the US, only Canada has published documents on the three most recent ICBP knowledge areas: stormwater management, sustainability, and LCA. Finally, this review paper focuses on pavements' mechanical behavior and design. In addition, it provides the sustainability seen as contributing to the HIE, the management of contaminant concentrations within infiltration related to permeability, and LCA.
