This study aims to evaluate economic and environmental benefits of porous pavement surface using life-cycle cost analysis (LCCA) and life-cycle assessment (LCA). The research will focus on application of porous surface for sidewalk. The life-cycle inventory data were collected from literature search, online database, and project records. The comparison study was conducted between pervious pavin...

Anatase, one of the polymorphs titanium dioxide (TiO2), has become most widely used semiconductor for photocatalytic materials due to its chemical and physical properties. However, researchers have been studying use alternative (e.g., ZnO, N-doped, C-doped TiO2) improve activity cementitious materials. In this paper, we propose a modification lightweight concrete by introducing mixed phases dio...

The basic oxygen furnace slag (BOF) was wide used in road construction, but there was a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA) containing stone mastic asphalt (SMA), porous asphalt (PA) and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag ...

• Penetration joints and adhesives on EPDM or asphalt roofing membranes (pitch pan) • Adhesives and sealants for crack filling or expansion joints for roofs, roads, bridges, and airport runways, providing excellent resilience, rut resistance, and adhesion to various substrates • Waterproof membranes, coatings or geomembranes for : parking decks, roof decks, terraces waste water, potable water (...

BACKGROUND Asphalt workers are exposed to polyaromatic hydrocarbons (PAHs) from hot mix asphalt via both inhalation and dermal absorption. The use of crumb rubber modified (CRM) asphalt may result in higher exposure to PAHs and more adverse effects. Our aim is to assess occupational exposure to PAHs from conventional and CRM asphalt paving by measuring PAH metabolites in urine, and to investiga...

Background Social support and school play a pivotal role in the development of oral health-related behaviors among students. This study was conducted to determine the relationship between stages of dental cleaning behavior change based on Trans-theoretical model with school role and social support in Iranian students. Materials and Methods In a cross-sectional study, 525 male and female student...
