A new pavement technology has been developed in Highway engineering: asphalt production is less susceptible to oxidation and the consequent damages. The warm mix (WMA) produced at a temperature of about (10-40) oC lower than hot paving. This done using one methods producing WMA. Although WMA's performance rather good, according previous studies, as it oxidation, possible modify some its propert...

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...

The conventional French fatigue test has yielded significantly different results for two asphalt materials with the same grade of pure asphalt. A research program was begun to study the influence of the asphalt nature on the fatigue behavior of asphalt materials. The program included full-scale experimentation on the circular test track of the Laboratoire Central des Ponts et Chaussees, laborat...

Rutting of flexible pavement is considered one of the major pavement distresses noted around the world and in Egypt. Many investigators showed at about 55 to 80% of rutting occurred in the surface layer. Rutting of asphalt surface layer may be due to many causes happened during construction phase and service phase. The main objectives of this research are to evaluate the impact of aggregate gra...
