Pavement rutting is one of the most common and destructive pavement distresses being observed in flexible pavements, which is primarily due to axle loads that exceed legal limit and high ambient temperatures, and also poor mix design is one of the cause of rutting. The drastic increase in traffic volume during last few decades has resulted in premature pavement failures of almost the whole road...

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...

The orthotropic steel deck (OSD) has been utilized successfully for thousands of bridges worldwide; however, fatigue cracking of the OSD has been observed frequently due to the complicated welded details combined with stresses that can be difficult to quantify, and the uncertainties in fatigue damage accumulation. In this paper, a fatigue reliability assessment method is proposed based on a com...

Abstract Globally, infrastructure faces the challenge of aging bridges and increasing traffic loads. Extended operational availability safety bridge structures can be enabled by Structural Health Monitoring (SHM) methods. For this, knowledge actual vehicle loads is crucial importance for evaluation remaining service life. Direct measurement moving loads, however, either very cumbersome requires...

Electronic controls cannot always compensate for the destabilization of a poorly designed vehicle caused by tire delamination. Axle tramp caused from rubber strips on the track showed axle skate [1]. Further research, reported at ESV 2007 [2] demonstrated that lumps on a single rear tire caused 15+ degrees/g of oversteer. The Engineering Institute has shown that the process of tire delamination...

It has become clear in the last few years that there is a trend towards integrated digital services. P d e l to the development of public Integrated Services Digital Network (ISDN) is service integration in the local area (e.g. a campus, a building, an aircraft). The types of services to be integrated depend very much on the specific local environment. However, applications tend to generate dat...

 Abstract—Currently, there are few user friendly Weigh-inMotion (WIM) data analysis softwares available which can produce traffic input data for the recently developed AASHTOWare pavement Mechanistic-Empirical (ME) design software. However, these softwares have only rudimentary Quality Control (QC) processes. Therefore, they cannot properly deal with erroneous WIM data. As the pavement perform...

The article studies the dynamics of crane movement mechanism to take measures for their reliable operation and reduce wear mechanisms. For this, following assumptions are accepted: transverse motion is not considered, engines electric drive considered; presented in form a seven–mass system, load suspension adopted as rigid.
 It has been established that account flexibility rope, with which...
