Assessing Environmental Sustainability Practices in Building Construction Projects in Tanzania: A Mixed‐Methods Approach

Engineering Reports, Volume 8, Issue 2, February 2026.
The study assesses environmental sustainability in 97 of Tanzania's building construction projects amid rapid urbanization. Using the LEED framework, the study reveals a low sustainability level. Barriers to sustainable practices are such as financial constraints, limited use of sustainable materials, and regulatory challenges.

Effect of Hot Mixing Duration on Blending, Performance, and Environmental Impact of Central Plant Recycled Asphalt Mixture

Buildings, 2022
When using a high concentration of reclaimed asphalt pavement (RAP) in a recycled hot-mix asphalt mixture (RHMA), the degree of blending of the reclaimed asphalt binder significantly affects the performance of the RHMA. Hence, it is essential to know the

Influence of Asphalt Emulsion Stabilization on Pavement Structural Behavior and Life Cycle Assessment (LCA)

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Effect of Reclaimed Asphalt Pavement on the Properties of Asphalt Binders

Procedia Engineering, 2013
AbstractUsing Reclaimed Asphalt Pavement (RAP) not only reduces the cost of new asphalt mixtures but also conserve the natural resources. To incorporate RAP in asphalt mix design, it is vital to know the amount and quality of the residual binder. In this research both conventional and Superpave methods were used to determine the virgin and residual ...

Preparation and Performance of SBR/SiO2‐Modified Emulsified Asphalt Mixtures Incorporating Recycled Aggregates

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To address the technical bottlenecks associated with the poor overall performance of emulsified asphalt mixtures incorporating high‐proportion (84 wt%) recycled asphalt pavement (RAP) aggregates, this study proposes a synergistic modification strategy using styrene‐butadiene rubber (SBR) and nano‐silica (SiO2), coupled with the regulation of cement and
