Abstract:- This study covers a literature search and review to obtain information on geotextile applications related to pavement construction. Applicable information-from this study, if sufficient, would then be used to prepare guidelines on design application, material specifications, performance criteria, and construction procedures for improving subgrade support with geotextiles in general aviation airport pavements. The study revealed that there are numerous design procedures available for using geotextiles in aggregate surfaced pavements and flexible pavement road construction. However, there is no generally accepted procedure for either type construction.

APPLICATION OF GEOTEXTILES IN PAVEMENT

Pumping in rigid pavements is defined as the migration of subgrade soil into the overlying layers, redistribution of materials under the slabs, and ejection of materials through joints. Pumping can compromise pavement performance. This study evaluated geotextiles as separation and filtration solutions to mitigate pumping and reduce the resulting pavement joint faulting.

A one-third scale Model Mobile Load Simulator MMLS3 was used to simulate cyclic loading on a scaled rigid highway pavement that has experienced some loss of load transfer. The results from four tests were compared to assess the effectiveness of geotextile in reducing pumping. The four experiments had identical configurations, except that a geotextile was placed at the subgrade-subbase interface in two tests.

Non-plastic saturated silt and partially saturated aggregate were used as the subgrade and subbase, respectively. Using a geotextile at the subgrade-subbase interface substantially reduced pumping. More fines accumulated in the subbase beneath the approach slab than the leave slab, which resulted in faulting of the slabs. However, the magnitude of this faulting was more pronounced for the cases without geotextile. To conclude, geotextile can be effective in mitigating pumping, leading to longer-lasting pavement systems.

Many experimental studies have shown that geosynthetic reinforcement of flexible pavement can be beneficial in terms of extending their service life and decreasing the required structural number of the pavement. Although numerous researches have performed experimental and numerical studies to evaluate the benefits of these reinforcements, comprehensive comparisons are lacking among the different investigations. This paper reviews typical field experimental studies on geosynthetic reinforcement of flexible pavement performed by various investigators.

Then, a unique formula is presented in this study, according to the performed comparison of the results. Although more investigations are needed to develop the presented method and general corrections, the results of this study can be used by the designers to evaluate the geosynthetic reinforcement of flexible pavements in their designs as well.

 - С вами все в порядке. Мы уж думали, вы все погибли. Сьюзан посмотрела на него отсутствующим взглядом. - Чед Бринкерхофф, - представился.  - Личный помощник директора. Сьюзан сумела лишь невнятно прошептать: - ТРАНС… Бринкерхофф кивнул.

 - Хейл хмыкнул. Он понимал: выбраться из шифровалки ему удастся, только если он пустит в ход все навыки поведения в конфликтных ситуациях, которые приобрел на военной службе. Стратмор придвинулся ближе, держа беретту в вытянутой руке прямо перед. - Как ты узнал про черный ход. - Я же сказал. Я прочитал все, что вы доверили компьютеру.

 Поссорились. На мгновение Беккер задумался. Потом изобразил смущенную улыбку.

    However, there is a lack of well-instrumented, full-scale experiments to investigate the effect of geotextile reinforcement on the pavement design. In this study, full–.
