چکیده
Aging of asphalt pavements typically occurs through oxidation the and evaporation lighter maltenes from binder. The main objective this study is to evaluate influence aging on performance paving materials.nAsphalt concrete mixtures, were prepared, subjected short term (STA) procedure which involved heating loose mixtures in an oven for two period (4 8) hours at a temperature 135 o C. Then it was subject Long (LTA) using (2 5) days periods 85 C Marshall compacted specimens. effect properties optimum content such as Properties, indirect tensile strength 25 C, Resilient Modulus resistance permanent deformation evaluated. impact Short-term long-term stiffness mixture increases by increasing that lead increase Stability, strength, resilient modulus, leads against deformation. 8 hr. causes stability, modulus be increased 52%, 34 % , 20% respectively compared with control while, decreased (33 %) mixture.

Effects of Warm-mix Asphalt Additives on Asphalt Mixture Characteristics and Pavement Performance
The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...

متن کاملInvestigation of Clay Balls in Asphalt Pavement
Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is 8 mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate 9 contamination of clay or soil, high aggregate moisture, and low production temperature at the 10 asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being 11 liquefied an...
