Measuring and Analyzing Pavement Texture Concrete Pavement Surface Characteristics Program

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...

Hydraulic Compatibility of Geotextile Drains with Fly Ash in Pavement Structures

The legislations have been promulgated in many states that remove barriers to large-scale beneficial re-use of waste materials. As a result, there is a renewed emphasis on incorporating suitable waste products into highway construction. Fly ash is one of these materials, and is increasingly being used as fill materials for highway embankments, and as grout mixes for road bases. In most cases, a...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
