RELEVANCE OF VALUE ENGINEERING TOWARDS ENVIRONMENT FRIENDLY ROADWAY PROJECTS

Abstract

With the increase of construction projects, planners should account for the effects on the environment as one of the most viable criteria. Value Engineering (VE) has proven to be a systematic approach that considers quality with cost in green environment problems. This paper presents how to use the (VE) to get the least impact of projects on the environment while using various alternatives in roadway projects. The case study is the Mansoura-Tanah/ Dekerness roadway at Dakahlia Governorate of 16 kmlength. The design alternatives include: (1) for thebase layer: crushed gravel vs. natural gravel, (2) for hot bituminous asphaltic concrete: crushed or natural gravel, and asphalt 60/70 vs. asphalt 40/50 and (3) for tack coat with rapid volatility asphalt: R.C 3000 vs. R.C 70. The re-use of agricultural waste in form of rice husk ash with different percentages as a substitute of limestone in asphaltic concrete has been considered incorporating its quality with Marshal Stability as indicator. Embodied Carbon emission resulting from all activities has been quantified in the project along with the cost of the carbon capture system. Estimation of the performance and cost to determine the value necessitates consideration of the Carbon Capture use and Storage (CCS) that uses a combination of technologies to capture the CO2 released by fossil fuel combustion or an industrial process, transport it to a suitable storage location, and finally store it (typically deep underground) where it cannot enter the atmosphere and thus contribute to climate change. CCS represents the term that incorporate embodied carbon emission of the various alternatives into the VE function. The results indicated that it is preferable to use natural stones as they contain a lower proportion of carbon with the same required quality. Asphalt 40/50 provides higher hardness while does not affect the cost of the project. The use of RHA as a substitute for limestone is recommended as cheap yet environment friendly alternative. Environmental prospective is very important to be considered for the future and may be rigorously implemented by integrating direct cost to the Carbon Capture use and Storage (CCS).
