Concrete infrastructure represents an enormous investment of materials, energy, and capital, results in significant environmental burdens social costs. There is ongoing effort to identify material alternatives conventional concrete. Life cycle assessment (LCA) important tool evaluate the performance alternative materials systems. Here, we present a comparative LCA two bridge deck systems over 60 year service life: one using steel expansion joints other based on link slab design concrete...
Even though the importance of ecosystems in sustaining all human activities is well-known, methods for sustainable engineering fail to fully account this role nature. Most demand ecosystem services, but almost none supply. Incomplete accounting very foundation well-being can result perverse outcomes from decisions meant enhance sustainability and lost opportunities benefiting ability nature satisfy needs an economically environmentally superior manner. This paper develops a framework...
At present, most synthetic organic materials are produced from fossil carbon feedstock that is regenerated over time scales of millions years. Biobased alternatives can be rapidly renewed in cradle-to-cradle cycles (1–10 years). Such extend landfill life and decrease undesirable impacts due to material persistence. This work develops a LCA for synthesis polyhydroxybutyrate (PHB) methane with subsequent biodegradation PHB back biogas (40–70% methane, 30–60% dioxide). The parameters this cycle...

Pavement systems provide critical infrastructure services to society but also pose significant impacts related large material consumption, energy inputs, and capital investment. A life-cycle model was developed estimate environmental resulting from production distribution, overlay construction preservation, construction-related traffic congestion, usage, end of life management. To improve sustainability in pavement design, a promising alternative material, engineered cementitious composites...

Preservation (maintenance and rehabilitation) strategy is the critical factor controlling pavement performance. A life-cycle optimization (LCO) model was developed to determine an optimal preservation for a overlay system minimize total energy consumption, greenhouse gas (GHG) emissions, costs within analysis period. Using dynamic programming techniques, LCO integrates assessment cost models with autoregressive deterioration model. To improve sustainability in design, promising alternative...
The authors have developed a new network-level pavement asset management system (PAMS) utilizing life-cycle analysis and optimization methods. Integrated assessment cost expand the scope of conventional PAMS from raw material extraction to end-of-life management. To aid decision-making process, applied model determine near-optimal preservation strategy for network. utilized geographic information (GIS) enhance by collecting, managing, visualizing data. proposed in this paper allows decision...
Within this work, life cycle assessment modeling is used to determine top design priorities and quantitatively inform sustainable decision-making for a prefabricated modular building. A case-study life-cycle was performed 5,000 ft 2 commercial building constructed in San Francisco, California, scenario analysis run examining the environmental impacts of various energy material substitutions, structural change. Results show that even highly energy-efficient building, priority still minimizing...
Deterioration due to reinforcement corrosion represents a significant cause of damage reinforced concrete bridges all over the world. Although numerous studies have identified substantial influence that can on failure structures under seismic loads, there has been comparatively less work done modelling structural vulnerability corrosion. Accurate and computationally efficient deterioration is an essential prerequisite for reliability or fragility prediction, life cycle cost impact...
