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

open access: yesEngineering 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.

Using recycled asphalt materials as an alternative material source in asphalt pavements

open access: yesKSCE Journal of Civil Engineering, 2014
Using recycled materials in pavement applications is a viable option to reduce costs and limit the environmental impact of road construction. During the past decades, many agencies in the U.S. have investigated the effect on pavement performance of adding Reclaimed Asphalt Pavement (RAP), and, more recently, Recycled Asphalt Shingles (RAS) to asphalt ...

Study on the Effects and Mechanisms of Different RPE/RPP Ratios on the Properties of Modified Asphalt

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 4, January 20, 2026.
Effects and Mechanisms of Different RPE/RPP Ratios on the Properties of Modified Asphalt. ABSTRACT Recycled polyethylene (RPE) and recycled polypropylene (RPP) are the most abundant types of plastic waste. Developing novel base asphalt modifiers (additives used to enhance the properties of asphalt) by blending RPE and RPP in different ratios is of ...
