The resulting equations thus obtained have been solved by adaptive Runge-Kutta method along with the shooting method. The effects of different physical parameters on velocity, microrotation, temperature and concentration distributions have been illustrated graphically. Also, the results for the skin-friction coefficient, the heat and mass transfer rates at the surface are tabulated for various values of fluid properties and the flow conditions. Numerical results show that mass transfer rate increase with the Schmidt number and chemical reaction parameter.&nbsp;</p> <p>&nbsp;</p> Khilap Singh ##submission.copyrightStatement## https://www.scigatejournals.com/publications/index.php/ijep/article/view/280 Wed, 31 Jan 2018 15:04:19 +0000 Assessment of Resilient Characteristics of Modified Asphalt Concrete https://www.scigatejournals.com/publications/index.php/ijep/article/view/289 <p>Asphalt concrete pavement is known to exhibit elastic behavior due to loading at cold weather and a combination of elastic, plastic and viscous behavior at hot climatic condition. However, the quality of the pavement can be assessed by its resilient characteristics (ability to retain its original shape after releasing the load). Distress of the pavement usually starts with micro cracking due to load repetition, while such cracks can heal by themselves in slow process under repeated loading, external or internal heating, and provision of rest period at ambient temperature. The aim of this work is to assess the resilient behavior of asphalt concrete after digestion of asphalt cement with polymer additives (SBS, LDPE, and rubber). Cylindrical Asphalt concrete specimens of 101.6 mm diameter and 127 mm height and beam specimens of 381.0 mm length, 76.2 mm width, and 76.2mm thickness have been prepared with optimum asphalt content requirement and with extra 0.5% asphalt above and below the optimum. Cylindrical specimens were tested under repeated compressive stress, while Beam specimens were tested under repeated flexure stress. The stress level for both testing techniques was 138 kPa at 25°C environment. The loading cycle was 0.1 second load application followed by 0.9 seconds of rest period. The test was conducted for 900 and 660 load repetitions for cylindrical and beam specimens respectively using the Pneumatic repeated load system (RPLS) to allow for the initiation of micro cracks. After the specified loading cycles, Specimens were withdrawn from the test chamber and stored in the oven for 120 minutes at 60 ° C to allow for micro crack healing, then were subjected to another loading and healing cycles. Permanent, total and resilient deformations were detected through LVDT. It was concluded that polymer additives and the micro crack healing cycles have positive impact on resilient modulus and deformation variables of asphalt concrete.</p> Saad Issa Sarsam, Sara Ali Jasim ##submission.copyrightStatement## https://www.scigatejournals.com/publications/index.php/ijep/article/view/289 Wed, 31 Jan 2018 15:08:23 +0000 Behavior of Warm Mix Asphalt Concrete under Moisture Damage https://www.scigatejournals.com/publications/index.php/ijep/article/view/290 <p>Due to the restrictions for protecting the environment, and the requirements to reduce fuel consumption, research work was started globally for verifying the possibility of implementation of warm mix asphalt concrete in pavement construction.&nbsp; In this work, the influence of moisture damage on the physical properties of warm mix asphalt concrete was investigated. A total of 72 cylindrical specimens of 100mm diameter and 63.5mm height have been prepared in the laboratory with (4, 4.5, 5, and 5.5) percentages of asphalt content using the typical Marshal hammer compaction procedure. Specimens have been separated into two sets, and each set was divided into three groups. The first group was subjected to indirect tensile strength determination, while the second group was tested for Marshall Properties. The third group was subjected to double punch shear strength determination. The second set of specimens was exposed to moisture damage process. Specimens were immersed in a water bath and subjected to water absorption under a vacuum pressure of 30 mm Hg for 10 minutes, then the specimens were transferred to a deep freezer and stored for 16 hours at -8°C. Specimens were allowed to thaw for two hours at the laboratory environment, then conditioned for another two hours at 20°C. The conditioned specimens were subjected to the physical properties determination as that of the first set. Test results were analysed and compared, and the influence of moisture damage on each of the physical properties was determined. It was concluded that the reduction in Marshal Stability, shear strength, and tensile strength due to moisture damage was 36%, 30%, 43% respectively.</p> Saad Issa Sarsam ##submission.copyrightStatement## https://www.scigatejournals.com/publications/index.php/ijep/article/view/290 Sat, 03 Feb 2018 15:07:13 +0000
