Assessment of Interlocking Concrete Block Pavement with By-Products and Comparison with an Asphalt Pavement: A Review

Abstract

This paper aims to review the performance analysis of interlocking concrete block pavement with by-products such as coconut fibers, and construction and demolition recycled materials, and to compare their skills with asphalt pavement, especially for light-traffic urban road applications. The focus is on mechanical behavior (mix parameters and the influence of by-products), pavement design, sustainability (the heat island effect), the management of contaminant concentrations within infiltration related to permeability, and Life Cycle Assessment. Considering the overall performance analysis, interlocking concrete block pavement was the most attractive alternative because it was approximately 33–44% cheaper in the maintenance process, cooler over a range of 2.2–15 °C, and more permeable by 0.4 cm/s to 0.6 cm/s than asphalt pavement, saving costs and improving drainage and human thermal comfort. However, asphalt pavement was around 35% cheaper during the construction phase (mainly due to energy consumption), and it presented a 32% lower nitrogen oxide concentration. This paper showed the advantages and disadvantages of both types of pavements. A further breakdown should be developed and integrated into the decision-making process about choosing between solutions.

Design and Construction Aspects of Concrete Block Paved Vertical Traffic-Calming Devices Located in Home Zone Areas

“…For example, Szpinek, in his publications [56,57], introduced an asphalt pavement distress and deformation rating system, relevant to the pavement condition assessment. A concrete block paving distress and deformation rating was, in turn, proposed in [51,58].…”

An Experimental Study on Innovative Concrete Block Solutions for Reconstruction

“…There has been increasing interest in the design and manufacture of novel interlocking masonry blocks for sustainable and cost-effective structures in recent years [20][21][22][23][24]. One such option is to make interlocking blocks with tongue and groove portions as well as projections that exactly fit together; this has been accomplished by partially replacing fly ash for cement in the block's manufacture.…”
