In the construction and maintenance of asphalt pavement, reclaimed pavement (RAP) is being widely used as a cheaper alternative to conventional hot mix (HMA). HMA incorporated with high RAP content (e.g., 40%), which most commonly used, may have prominent adverse effects on life cycle, performance properties, related costs. Thus, before utilizing RAP, it essential investigate whether still econ...

The present research aims to conduct laboratory assessment on fatigue phenomenon in warm mix asphalt modified with nano-silica and including reclaimed asphalt pavement materials by the aid of review on self-healing behavior and measurement of validity of laboratory results by modeling via neural artificial network in neutral network of SPSS software. For this purpose, 2% weight of sasobit and 3...

In this paper, it was performed physical, mechanical, and microscopic analyzes on samples of industrial waste foundry sand (WFS) hot mix asphalt mixtures (HMA) containing WFS as fine aggregate. The HMA produced replacing 50 100 % the aggregate (passing 4.38 mm by sieve) (by weight) with a dense gradation suitable for pavement course layers. A “control” mixture used without WFS. results typical ...

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...
