“…Sustainability studies should consider the inseparable nature of environmental, social and economic aspects of development activities (Huang et al 2016;United Nations, 2013;and Veldhuizen et al, 2015). Sustainability index representations have developed in various industries and for different purposes (Chang et al, 2018). However, the assessment of social factors has not been yet consolidated in urban studies.…”

Narrow trenches are a common technique for the installation of utility pipelines of small diameter. The excavated soil is not always appropriate as landfill and, in those cases, an appropriate soil from somewhere else (ex. a borrow pit or another construction site) should be used instead (classical solution, CS). Another common solution is to use a controlled low-strength (cementitious) material (CLSM) as backfill instead of compacted soil. However, both solutions lead to increased raw material consumption, waste generation, need for transportation, and CO2 emissions. In an attempt to address these issues, researchers developed an eco-trench (ECO) that reuses the excavated soil of narrow trenches to produce a controlled low-strength material to be used as landfill. Although technically viable, the sustainability of this solution versus the traditional solution has not been properly addressed. Hence, this paper aims to develop a method for the sustainability assessment of trenches. The Sustainability Index of Trenches (SIT), based on the MIVES decision-making method, enables the assessment and prioritisation of different types of trenches according to sustainability criteria. Criteria, indicators, weights and value functions were specifically defined based on seminars with experts in the field of utility services and construction. A case study was performed in which four types of trenches (CS, CS with recycling CS+R, CLSM and ECO) were assessed and prioritised according to SIT. ECO resulted in the most sustainable alternative with a SIT of 0.80 out of 1 followed by CS+R, CS and CLSM with SITs of 0.63, 0.40 and 0.38 respectively. The sensitivity analysis showed consistent results in different scenarios. These findings demonstrate the capability and reliability of SIT as a decision-making tool for the 2 evaluation of the sustainability of different construction processes for trenches and the prioritisation of the most suitable solution for different situations.

“…Compared to Cj, Ci has a strong importance 1/2, 1/3...1/5 The importance of Ci compared to Cj is opposite to the above description (1)The judgment matrix of the expert with the number k is multiplied by rows to obtain the value j i W . The obtained value is then subjected to an n-th power root operation to obtain the value, which is then normalized.…”

Highway construction is the foundation of national strategic development and bears important responsibilities for social and economic development. With the rapid development of China's highway industry, the impact of the entire life cycle of highway construction, operation, and maintenance on resources and environment is increasingly deepening. The 14th Five Year Plan mentions green economic and social development, and the selection of highway routes lays the foundation for the environmental impact of the entire life cycle of highways, which is closely related to achieving sustainable development of highway construction. This article carries out the evaluation of the green degree of highway route selection in Jiangsu Province, and verifies the practical significance of the model through the design and route selection of the Nantong Ring Expressway, in order to guide the sustainable development of green highway construction in Jiangsu Province from the basic stage of route selection.

“…In terms of evaluation objectives, some studies established a green highway improvement and expansion road evaluation system based on the Greenroads index system for highways, highlighting the goal of environmental protection and considering evaluation criteria such as ecological protection, pollution prevention, resource conservation, energy saving, and emission reduction [11,14,21,22]. El et al [2] argued that previous studies did not adequately integrate the concept of sustainability into the management of road infrastructure projects and proposed the comprehensive highway sustainability index (CHSI) for assessing the three main categories of sustainable development economics, social criteria, and environmental criteria to improve the level of sustainability in road construction.…”

As the volume and scale of urban expressways continue to increase, renewal remains a concern for urban development. The renewal and decision-making of an urban expressway need to be endowed with new concepts to adapt to the rapid development of cities. Nevertheless, in addition to considering road factors such as facility conditions, driving conditions, and environmental protection, the existing evaluation system lacks comprehensive consideration of factors that improve resilience and adapt to future urban development, and it lacks a quantifiable general update evaluation system. Thus, the establishment of a comprehensive renewal indicator system and a mixed evaluation framework is a challenge. This study proposes an evaluation framework of expressway renewal indicators that integrates the three dimensions of macro, meso, and micro based on the fuzzy Delphi method, the fuzzy AHP method, and the TOPSIS method. A q-rung orthopair fuzzy linguistic set was used to handle expert uncertainty information in the process of conducting fuzzy evaluations. The indicators were refined into general and quantifiable evaluation indicators to improve their versatility. Moreover, the renewal value of expressways was measured and calculated using the TOPSIS method, and four renewal intervals were divided according to the calculation results. As a result, 28 renewal indicators were screened out, and the five factors with the greatest impact on renewal were the demand for transport development, the renewal of facility and service functions, the upgrading of institutional resilience, structural renewal, and economic development. The model was applied to eight expressways in Shanghai to calculate the renewal degree value and divide the renewal status. The model could identify the renewal needs of each road to guide the renewal decision. This study proposes an evaluation model to measure urban expressway renewal studies and provides a reference for urban renewal in the area of sustainable development
