The impacts of aggregates and warm mix asphalt additives on the moisture damage characteristics of unmodified and polymer-modified asphalt mixtures were examined in the current study. AASHTO T283 procedure was employed for the purpose of assessing the moisture susceptibility of mixtures. For the production of asphalt…

Aggregates play a crucial role in geotechnical engineering, serving applications such as railway and road construction, hydraulic structures, and as the base material for concrete. While various tests are commonly employed to characterize aggregates, the Aggregate Impact Value (AIV) can also provide indirect informati…

Düşük sıcaklıklarda gerçekleşen kömür oksidasyonu, kömürün kendi kendine ısınmasına ve nihayetinde kendiliğinden yanmasına (spontaneous combustion, sponcom) yol açan temel ekzotermik süreçtir. Bu olgu; kömürün üretimi, depolanması ve taşınması sırasında önemli güvenlik riskleri oluşturmakta, çevresel etkiler ve ekonom…

Assessing the structural performance of concrete is vital for monitoring structures and planning interventions, especially after earthquakes. Accurately determining concrete strength ensures safety and cost-effective maintenance. Mechanical properties such as compressive strength, elasticity, and porosity are measured…

PURPOSE: This study evaluated the effects of different surface treatment methods and thermocycling on the shear bond strength (SBS) of repaired composite resin restorations across three composite types (nanohybrid, bulk-fill, and microhybrid). METHODS AND MATERIALS: A total of 252 disk-shaped specimens (Ø20 × 5 mm, n…

Airport runway pavements are subjected to severe mechanical stresses and surface abrasion from repeated aircraft landings and take-offs, which accelerate deterioration, shorten service life, and increase maintenance costs. Conventional concrete, while widely used, is limited by brittleness, low tensile capacity, and v…
