Fatigue performance of PVA fibre reinforced cementitious composite overlays

Pavement maintenance and rehabilitation is as much important as the construction work itself. In this scope, applying the correct and efficient repair method is highly critical for economic and technical reasons. Depending on the damage level, many alternative repair methods exist. Using an overlay is one common method, where a new layer can be directly applied over or replace the top part of an existing pavement. This overlay can be made from asphalt or concrete as well. With the advances in the concrete technology, the long service life of concrete pavements compared to asphalt let this overlay gains importance recently. Yet, the rigid nature of concrete requires a high thickness for an overlay. In this work, Engineered Cementitious Composite (ECC) type of concrete was suggested to be used as an overlay considering its ability, with a less thickness, to reduce the reflection of the cracks from the old pavement. To testify this property, the performance of two ECC mixtures as a concrete pavement overlay was investigated under fatigue loading. Using Weibull distribution, the failure probability of these mixtures was determined, and it was shown that the mineral admixture type utilized significantly affects the fatigue performance of ECC.

The maintenance and rehabilitation of a pavement during its service life is as much important as the construction works of this pavement. In this scope, applying the correct and efficient repair method is highly critical for economic and technical reasons. Depending on the damage level of the pavement, there are many different methods that can be used to repair the pavement. The use of an overlay is one of the most common methods, where a new layer can be applied directly over or replace the top part of an ...
Service life assessment of existing highway bridges with no planned regular inspections
Caner, Alp; Yanmaz, Ali Melih; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2008-03-25)
Safety of a highway infrastructure system depends very much on the proper maintenance of bridges. The level of required maintenance is, typically, determined through a series of regular field inspections with the guidance of safety–economy trade-off. In Turkey, bridge maintenance, repair, and rehabilitation are currently performed on an as-needed basis. Time-dependent reliability analysis cannot be utilized for Turkish bridges for the time being since the majority of the bridges are either not regularly ins...
Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
An investigation into the implementation of construction automation and robotics technologies for construction waste management
Kılıçkan Öztürk, Sabire Melek; Elias Özkan, Soofia Tahira; Department of Architecture (2022-8)
The construction industry is responsible for tons of construction waste. It is crucial to take the necessary precautions to avoid the impacts of construction waste on the environment. With the help of developments in automation technology and building information modeling systems, robotics in the construction industry is getting more common every day. It is argued that construction robots can be effective in the management of construction waste. This study aims first to understand the reasons for construct...
Seismic behavior of semi-precast concrete shear walls
Golnesa Karimi, Zindashti; Binici, Barış; Canbay, Erdem (null; 2017-10-11)
Successful seismic performance of well-designed and constructed precast concrete members is crucial for sustainable, economical and high speed construction. The main disadvantage of precast concrete is the difficulty of detailing the connection region between the vertical and horizontal load bearing elements to ensure structural integrity. Double wall system, being a semi-precast approach, consists of two precast reinforced concrete layers encasing a cast-in-place concrete layer which is usually employed to...
