This represents a typical range of reliability levels encountered for Interstate highways. By looking at several different design periods and reliability levels this example gives an idea of the relative influence of these inputs. This step involves converting the daily traffic volume into an annual ESAL amount.

Flexible Pavement Empirical Design Example

Guide to Pavement Technology Part 2: Pavement Structural Design provides advice for the structural design of sealed road pavements. The advice has been generally developed from the approaches followed by the Austroads member agencies. However, as it encompasses the wide range of materials and conditions found in Australia and New Zealand, some parts are broadly based. This Part covers the assessment of input parameters needed for design, design methods for flexible and rigid pavements and gives guidance on the economic comparisons of alternative pavement designs. Austroads' pavement design software, AustPADS conducts advanced mechanistic analysis of the response-to-load of road pavements.

Normally, overlays of existing pavements are used to increase the load-carrying capacity of an existing pavement or to correct a defective surface condition on the existing pavement. Of these reasons, the first requires a structural design procedure for determining the thickness of overlay, whereas the second requires only a thickness of overlay sufficient to correct the surface condition and no increase in load-carrying capacity is considered. The design method for overlays included in this chapter determines the thickness required to increase load- carrying capacity. The study section is a part of the National Highway No. The long-term objective of the project is to construct a highway link, which is an integral part of a National Highway System, which can serve the countrys transportation needs in the future, before any actual construction can begin many factors affecting the population near by the proposed project and future road users have to be examined.

 Шифр-убийца? - переспросил Бринкерхофф. Джабба кивнул: - Да. Нужно ввести ключ, останавливающий червя. Все очень все. Мы признаем, что у нас есть ТРАНСТЕКСТ, а Танкадо вручает нам шифр-убийцу.

Сьюзан подумала о Стратморе, о том, как мужественно он переносит тяжесть этого испытания, делая все необходимое, сохраняя спокойствие во время крушения.


И на другом конце сразу же сняли трубку. - Buenas noches, Mujeres Espana. Чем могу служить. Беккер держался той же версии: он - немецкий турист, готовый заплатить хорошие деньги за рыжеволосую, которую сегодня нанял его брат. На этот раз ему очень вежливо ответили по-немецки, но снова сказали, что рыжих девочек у них .

Цифровая крепость оказалась фарсом, наживкой для Агентства национальной безопасности. Когда Стратмор предпринимал какой-либо шаг, Танкадо стоял за сценой, дергая за веревочки. - Я обошел программу Сквозь строй, - простонал коммандер.

Беккер не мог ждать. Он решительно поднял трубку, снова набрал номер и прислонился к стене. Послышались гудки. Беккер разглядывал зал. Один гудок… два… три… Внезапно он увидел нечто, заставившее его бросить трубку.
