Effects of Aggregate Gradation on Resilient Modulus and CBR in Unbound Granular Materials
Resilient modulus and California Bearing Ratio (CBR) in unbound granular materials are the key technical characteristics of layers in a flexible pavement design. Among the factors affecting these two parameters, the aggregate gradation is the most important. Using particle size distribution curve developed by AASHTO, together with other considerations mentioned in the related regulations have y...

ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...
15 صفحه اولDurability of Cementitiously Stabilized Aggregate Bases for Pavement Application
Variations in environmental conditions have been recognized by pavements engineers as a major factor affecting pavement performance. These variations resulting from freeze-thaw (F-T) or wet-dry (W-D) actions can significantly affect the engineering properties of pavement material. In this study, the effect of W-D and F-T cycles, on the resilient modulus (Mr) of stabilized aggregate bases is exa...
متن کاملModular ratios for unbound granular pavement layers
Unbound granular pavement layers show a characteristic increase in moduli from the subgrade to the surface. The ratio of moduli between successive layers provides a direct and effective measure of pavement quality that makes due allowance for site conditions and seasonal effects beyond a contractor’s control. The modular ratio is therefore an effective indicator for performance-based specificat...

Hot-mix asphalt (HMA) plays a vital role in the U.S. transportation system, and will continue to do so into the new millennium. Thus it is important to examine both the state of the art of and future prospects for HMA in a number of key areas, including the role of the user agency or owner, materials, processing, transportation, lay-down procedures, testing for quality and performance, work zon...
