Abstract The Qinghai-Tibet Railway has been operating safely for 16 years in the permafrost zone and railroad subgrade is generally stable by adopting cooling roadbed techniques. However, settlement caused degradation of embankment-bridge transition sections (EBTS) one most representative severe distresses. A field survey on 440 bridges (including 880 EBTSs) was carried out employing terrestria...

The syndrome of this disease is observed in gunshot injuries large nerve trunks, abundantly supplied with vessels, and expressed unbearable, burning stabbing pains, which are aggravated at physical mental distresses the patient. These pains usually come on 2nd week after injury do not give patient any rest day or night. At same time, vasomotor disorders detected patients.

Joint lockup due to dowel misalignment significantly affects joint and concrete pavement performance by causing distresses. The current paper presents an experimental study assess the effectiveness of standard pull-out test in evaluation effect on Jointed Plain Concrete Pavement (JPCP). tests were conducted at two different ages ; 3 28 days. results showed that or individually pulling misaligne...

In the scenario of technological changes that were introduced by the waves of globalisation and the construction of an Information Society, together with recent national distresses, Brazilian cities face the challenge of combining competitiveness and sustainable urban development. Having in mind this complex landscape, this article seeks to analyse the experience Rio Operations Centre (ROC) of ...

Polymer-modified bitumen is used to combat different pavement distresses and to increase the life span of pavement. Unmodified bitumen cannot perform better with the range extreme minimum and maximum pavement temperatures. The polymers commonly used to modify the bitumen are ethylene vinyl acetate (EVA) styrene butadiene styrene (SBS). The aim this study to compare the performance of EVA modifi...

In current scenario several commercial and social organizations are using computer networks for their business and management purposes. In order to meet the business requirements networks are also grow. The growth of network also promotes the handling capability of large networks because it counter raises the possibilities of various faults in the network. A fault in network degrades its perfor...
