properties of aggregates and quality differences in the same type of bitumen, as well as the dosage rate of reclaimed asphalt on the relevant material parameter of the analytical pavement design method are not known. Due to that, in this study, the influence of the above mentioned characteristics on relevant material parameters has been determined and analyzed by means of the analytical pavement calculations method. Therefore, material parameters for several asphalt mixes for asphalt wearing course, asphalt binder course and asphalt base course have been determined. Thereby several bitumens of the same type from different producer鈥檚 have been used. In addition, asphalt base course materials with three different dosages of reclaimed asphalt have been produced and tested. As material parameter according to the German analytical pavement design guide(RDO Asphalt), the stiffness鈥檚 at different temperatures and fatigue behavior have been determined. The findings of asphalt base course materials produced with several pen graded bitumen from different producers and different dosages of reclaimed asphalt indicate the distinct impact on fatigue behaviors and mechanical properties. The calculated test results of the analytical pavement design method show significant differences in the lifetimes. The pavement design calculation is to carry out by means of the actual material parameter. The calculated lifetime of the asphalt base course materials differentiates by the factor 3.2. The determining test results of bitumen characteristics meet the requirement according to the German Standards. But, further investigations of bitumen in different aging conditions show significant differences in their quality. The fatigue behavior and stiffness of asphalt pavement improves with increasing dosage of reclaimed asphalt. Furthermore, the type of aggregates used shows no significant influences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reclaimed%20asphalt%20pavement" title="reclaimed asphalt pavement">reclaimed asphalt pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20differences%20in%20the%20bitumen" title=" quality differences in the bitumen"> quality differences in the bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20time%20calculation" title=" life time calculation"> life time calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=Asphalt%20mix%20with%20RAP" title=" Asphalt mix with RAP"> Asphalt mix with RAP</a> </p> <a href="https://publications.waset.org/abstracts/137874/influence-of-the-quality-differences-in-the-same-type-of-bitumen-and-dosage-rate-of-reclaimed-asphalt-on-lifetime" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Influence of Driving Speed on Bearing Capacity Measurement of Intra-Urban Roads with the Traffic Speed Deflectometer(Tsd)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pahirangan%20Sivapatham">Pahirangan Sivapatham</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Esser"> Barbara Esser</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Grimmel"> Andreas Grimmel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In times of limited public funds and, in particular, an increased social, environmental awareness, as well as the limited availability of construction materials, sustainable and resource-saving pavement management system, is becoming more and more important. Therefore, the knowledge about the condition of the structural substances, particularly bearing capacity and its consideration while planning the maintenance measures of the subordinate network, i.e., state and municipal roads unavoidable. According to the experience, the recommended ride speed of the Traffic Speed Deflectometer (TSD) shall be higher than 40 km/h. Holding of this speed on the intra-urban roads is nearly not possible because of intersections and traffic lights as well as the speed limit. A sufficient background of experience for the evaluation of bearing capacity measurements with TSD in the range of lower speeds is not available yet. The aim of this study is to determine the possible lowest ride speed of the TSD while the bearing capacity measurement on the intra-urban roads. The manufacturer of the TSD used in this study states that the measurements can be conducted at a ride speed of higher than 5 km/h. It is well known that with decreasing ride speed, the viscous fractions in the response of the asphalt pavement increase. This must be taken into account when evaluating the bearing capacity data. In the scope of this study, several measurements were carried out at different speeds between 10 km/h and 60 km/h on the selected intra-urban roads with Pavement-Scanner of the University of Wuppertal, which is equipped with TSD. Pavement-Scanner is able to continuously determine the deflections of asphalt roads in flowing traffic at speeds of up to 80 km/h. The raw data is then aggregated to 10 m mean values so that, as a rule, a bearing capacity characteristic value can be determined for each 10 m road section. By means of analysing of obtained test results, the quality and validity of the determined data rate subject to the riding speed of TSD have been determined. Moreover, the data and pictures of the additional measuring systems of Pavement-Scanners such as High-Speed Road Monitor, Ground Penetration Radar and front cameras can be used to determine and eliminate irregularities in the pavement, which could influence the bearing capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bearing%20capacity%20measurement" title="bearing capacity measurement">bearing capacity measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20speed%20deflectometer" title=" traffic speed deflectometer"> traffic speed deflectometer</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-urban%20roads" title=" inter-urban roads"> inter-urban roads</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavement-Scanner" title=" Pavement-Scanner"> Pavement-Scanner</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20substance" title=" structural substance"> structural substance</a> </p> <a href="https://publications.waset.org/abstracts/137873/influence-of-driving-speed-on-bearing-capacity-measurement-of-intra-urban-roads-with-the-traffic-speed-deflectometertsd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Effect of Diindolylmethane on BBN-Induced Bladder Carcinogenesis in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sundaresan%20Sivapatham">Sundaresan Sivapatham</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Prabhu"> B.

Chemoprevention is promising in the realm of cancer prevention and it has been shown to reduce the risk of development of carcinoma in highly susceptible individuals such as those with known genetic mutations or high level of risk factors. The present study is aimed at the need of early detection of bladder cancer in order to improve performance in the treatment of this disease. Consumption of certain natural products like DIM is associated with a reduction in cancer incidence in humans. The study showed the protective effects of Diindolylmethane in N-Butyl-N-(4-hydroxybutyl) nitrosamine treated rats. Results of the study had shown the changes in the tumor markers, biomarkers and histopathological alterations in experimental rats when compared to control rats. The protective effects of DIM were shown from the results of cell proliferation, apoptotic markers and histopathological findings when compared with experimental control animals. Hence, our results speculate that the tumor markers, apoptotic markers, histopathological changes and cell proliferation index measured as PCNA serves as an indicator suggestive of protective effects of DIM in BBN induced urinary bladder carcinogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bladder%20cancer" title="bladder
