Warm Mix Asphalt (WMA) is a set of technologies that uses additives to reduce binder viscosity and increase mixture workability, which provides complete coating aggregates at lower temperatures around 100 °C 130 °C. Organic wax or Sasobit one the can be used for this purpose. It reduces melting point wax, allows production asphalt mixes temperatures. This attempt proposes new relationships elas...

Asphalt is a black, thermoplastic, hydrocarbon material extracted from crude oil and widely used in road construction all over the world. In order to meet requirements of technology, asphalt always needs be heated flow state process mixing paving, during which large amount fume released. complex mixture inorganic compound gases, volatile organic compounds particulate matter, poses serious threa...

The employed cross-sectional research design, whereas sample size of 63 respondents that, include 59 WMO 4 RM WMA from Salaam were involved. A simple random sampling technique was used selection WMO, purposive regional managers (RM) four administrative region...

CONTEXT Observational studies have shown that psychosocial factors are associated with increased risk for cardiovascular morbidity and mortality, but the effects of behavioral interventions on psychosocial and medical end points remain uncertain. OBJECTIVE To determine the effect of 2 behavioral programs, aerobic exercise training and stress management training, with routine medical care on p...

The adoption of warm mix asphalt (WMA) technologies is well accepted due to its promising environmental benefits, however, their long-term field performance not understood. This study focused on the rutting resistance WMA and companion hot (HMA) based 83 samples collected from 28 projects across United States covering four climate zones, quantified impacts for various as compared HMA. Field cor...

Sustainability and durability are the key requirements of pavement structure. asphalt structure involves utilization Warm Mix Asphalt (WMA) technologies with addition Reclaimed Pavement (RAP), where performance parameters like fatigue fracture resistance properties etc. Utilizing RAP content in mix increases mixing compaction temperature which may degrade asphalt. Hence, numerous studies have r...

Recently, interest in the use of projectiles research on recycling waste materials for construction applications has grown. Using recycled asphalt concrete pavement, meantime, become a topic due to its significant benefits, such as cost savings and reduced environmental impacts. This study reports comprehensive experimental conducted using typical mechanical milling waste, iron filing (IFW), an...
