Concrete block pavement (CBP) can be an alternative pavement to asphalt and concrete pavements. CBP is formed from individual concrete paving blocks (CPBs) that fit next to one another on a suitable sub base leaving a specific joint space among them to be filled with jointing sand. CBP differ from other pavements according to their mechanical behavior, manufacturing technique, structural design, installation technique and structural behavior. For a serviceable pavement all of these subjects have to be studied. The literature about the mechanical behavior of CPBs is not adequate. This study aims to determine the performance of CPBs formed from different mixes prepared with a white portland cement. For this purpose, 10 mixes with different cement contents and W/C ratios and 2 mixes from a commercial CPB manufacturer were tested. The compressive strength, tensile splitting strength, abrasion resistance, density and % water absorption tests were performed on each mix at 7, 14, 28 days. It was concluded that, the cement content in the mix, optimum water volume for a given cement content, the way the manufacturing equipment is operated and their interaction was effective on the mechanical properties of CPBs. It was also observed that there was no handicap to stop the abrasion resistance test at 8*22 revolutions instead of 16*22 revolutions given in TS 2824.

Predicting long term strength of roller compacted concrete containing natural pozzolan by steam curing Aslan, Özlem; Turanlı, Lutfullah; Department of Civil Engineering (2006) Roller Compacted Concrete (RCC) is new technology gaining popularity in the recent years due to its low cost, rapid construction, and using opportunity of by-products. RCC is widely used in the world. However, the use of RCC has been restricted to construction of few cofferdams, and limited to local use in dam construction up to date. In this thesis, two types of cement, two types of natural pozzolan, aggregates with varying gradations, and a type of water reducing chemical admixture were used. Prior to car...
Investigation of Moisture Dissipation in Foam-Based Warm Mix Asphalt Using Synchrotron-Based X-Ray Microtomography Kutay, M. Emin; Öztürk, Hande Işık (American Society of Civil Engineers (ASCE), 2012-06-04) Foam-based Warm Mix Asphalt (WMA) technologies decrease the viscosity of the asphalt so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and temperature drops. During the process of dissipation of foam, depending on the environmental conditions, the moisture may not escape and may be trapped inside the mixture. This trapped moisture can cause detrimental failures by breaking the adhesive bonds between the aggregates and the asphalt bind...
Thermal fatigue behavior of asphalt concrete: A laboratory-based investigation approach Arabzadeh, Ali; Güler, Murat (Elsevier BV, 2019-04-01) Cracks due to thermal fatigue phenomenon can lead to serious degradations in both structural performance and service quality of asphalt concrete roadways. Thermal fatigue cracks occur in regions with moderate climates as a result of cyclic thermal strains/stresses within the restrained pavement layers. In this study, an experimental setup is developed to measure thermal fatigue resistance of asphalt concrete specimens under constant strain amplitude loading. To simulate thermal fatigue behavior of asphalt c...
Evaluation of air void parameters of fly ash incorporated self consolidating concrete by image processing Özerkan, Nesibe Gözde; Yaman, İsmail Özgür; Department of Civil Engineering (2009) Self consolidating concrete (SCC) is defined as an innovative concrete that does not require vibration for placing and compaction and it is able to flow under its own weight, completely filling formwork and achieving full compaction. Although significant amount of research has been carried out regarding the fresh properties, mix design, placing methods and strength of various SCC mixes, only a very limited amount of work has been done to assess the durability performance of SCC. Concretes in cold climates a...
Comprehensive Evaluation of AIMS Texture, Angularity, and Dimension Measurements Mahmoud, Enad; Gates, Leslie; Masad, Eyad; Erdoğan, Sinan Turhan; Garboczi, Edward (American Society of Civil Engineers (ASCE), 2010-04-01) Aggregates are the most widely used construction materials in the world in structures built from both asphaltic and portland cement concrete composites. The performance of these composites is affected by aggregate shape characteristics (e.g., angularity, texture, and dimensions). The aggregate imaging system (AIMS) is a computer automated system that was developed to measure aggregate shape characteristics using digital camera images of aggregates. This paper addresses four issues concerning AIMS measuremen...
