Adviser: MARJORIE S. VELASCO, Ph.D. This study used a quantitative research approach, such as the descriptive survey method, to examine the performance and sustainability of locally sourced materials used in road construction projects of DWPH 1st District, Talavera, Nueva Ecija, during the Calendar Year 2025. A researcher-made survey instrument was pre-tested by 15 employees of DPWH 2nd District, Cabanatuan City, using Cronbach’s Alpha and was found to be reliable. The survey questionnaire was administered to 143 employees from different agency departments after approval was sought from the proper authorities. Upon retrieval of the instrument, it was examined using descriptive statistics. The results illustrate that the mean age of the respondents was 31.33. Males were single, obtained Bachelor’s degrees, and had 5.32 years in service. The performance of locally sourced materials regarding durability, compressive strength, and resistance to weathering was strongly agreed upon. The respondents strongly agreed on the sustainability of locally sourced materials, including economic, social, and environmental. The respondents identified challenges faced in integrating sustainability into road construction projects while using locally sourced materials, including limited availability, increasing cost, unregulated extraction, limited understanding of advanced sustainability practices, and inconsistent quality of locally sourced materials.
