Design Method and Evaluation Criteria on Gyratory Compaction Based Cold-Mixed and Cold-Laid Recycled Asphalt Mixture

Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures

Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

Laboratory Evaluation of High Asphalt Binder Replacement with Recycled Asphalt Shingles (ras) for a Low N-design Asphalt Mixture

This study investigated the effect of high asphalt binder replacement for a low N-design asphalt mixture including RAP and RAS on performance indicators such as permanent deformation, fracture, fatigue potentials, and stiffness, was studied. An experimental program included complex modulus, fracture, overlay reflective cracking resistance, wheel track permanent deformations, and push-pull fatig...

Evaluation of the Effects of Recycled Asphalt Pavement (rap) on an Ndot Hma Mixture

task-based language teaching in iran: a mixed study through constructing and validating a new questionnaire based on theoretical, sociocultural, and educational frameworks

جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...

Effect of crumb rubber gradation on a rubberized cold recycled mixture for road pavements

a r t i c l e i n f o Cold recycling technique represents the most environmental friendly solution for pavement rehabilitation nowadays. In fact, this technique allows the use of the highest percentage of reclaimed asphalt avoiding the energy consumption related to aggregates heating required by the traditional hot mix asphalt design. The mix design represents a key phase of the cold mix produc...
