  • Waste and by-product status of slag and concrete environmental damage
    • Authors: Svetlana Pushkar
      Pages: 743 - 750
      Abstract: Canadian Journal of Civil Engineering, Volume 44, Issue 9, Page 743-750, September 2017.
      The goal of this study is to evaluate the effect of ground granulated blast-furnace slag (GGBFS) status (i.e., “waste” or “a by-product”) on (i) the selection of the best GGBFS concrete, in terms of the environmental impact, and (ii) the relationship between environmental damage intensity (EDI) and compressive strength (CS) for both high- and normal-strength concretes. The best GGBFS concretes, as well as the relationships between EDI and CS, are controversial with respect to different GGBFS statuses. In particular, for high-strength concretes, replacement of the waste status with the by-product status for GGBFS has the opposite influence on the selection of the best GGBFS concrete (in terms of the environment). For high- and normal-strength concretes, if GGBFS is considered as waste, then no consistent relationship between EDI and CS is found, whereas if GGBFS is considered as a by-product, then a relationship is observed between increased CS and decreased EDI.

  • Calibration et validation d’un modèle de prédiction de l’uni des
           chaussées flexibles
    • Authors: Djonkamla Youdjari, Guy Doré, Jean-Pascal Bilodeau
      Pages: 751 - 759
      Abstract: Canadian Journal of Civil Engineering, Volume 44, Issue 9, Page 751-759, September 2017.
      L’objectif principal de cet article est de calibrer le modèle d’uni en termes de l’index de rugosité international (IRI), développé par une nouvelle approche. Afin d’atteindre cet objectif, la méthodologie utilisée s’appuie sur les données de bases de données du programme de la performance à long terme des chaussées (LTPP) et du ministère des Transports du Québec (MTQ) d’une part, et d’autre part, de la cueillette des paramètres géotechniques issus des essais de caractérisations des échantillons, prélevés à chaque 5 m le long de cinq différents sites du Québec. Les coefficients de calibration requis ont été déterminés avec succès. Le second objectif de l’article est la validation du modèle. Par manque de paramètres géotechniques à chaque 5 m le long des sections identifiées pour réaliser cet objectif, le principe de niveau d’utilisation du modèle d’uni a été développé. Trois niveaux d’utilisation du modèle ont été développés et le modèle a été validé au troisième niveau d’utilisation avec un niveau de succès acceptable.

  • Design procedure for liquid storage steel conical tanks under seismic
           loading
    • Authors: Ahmed Musa, Ashraf A. El Damatty
      Pages: 760 - 773
      Abstract: Canadian Journal of Civil Engineering, Volume 44, Issue 9, Page 760-773, September 2017.
      Steel conical liquid tanks are widely used for the purpose of liquid storage. Despite the fact that some of these tanks have failed lately, most of the seismic design guidelines focus on the design of steel cylindrical tanks with the only design guidelines for conical tanks based on using an equivalent cylinder approach, which is not based on any theoretical or experimental basis. In this study, a simplified procedure is proposed to design steel conical tanks subjected to horizontal and vertical excitations. The proposed procedure is based on satisfying a design formula that combines the ratio of seismic demand to the tank resistance due to horizontal and vertical excitations including geometric imperfections. The design procedure is then validated by comparing its outcomes with those obtained using time history analysis. The study is carried out numerically using an in-house nonlinear finite element model.

  • Defect based deterioration model for sewer pipelines using Bayesian belief
           networks
    • Authors: Mohamed Elmasry, Alaa Hawari, Tarek Zayed
      Pages: 675 - 690
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      A defect based deterioration model to determine the condition ratings in a probabilistic manner for sewer pipelines is presented in this paper. Bayesian belief network (BBN) is used to develop a static model using probabilities of occurrences, and conditional probabilities from observations of existing sewage network. Time dimension is introduced to the developed BBN model by using logistic regression as temporal links required to construct a dynamic Bayesian belief network (DBN). The accuracy of the model’s prediction is examined using actual data where the mean absolute error and root mean square error for the BBN model resulted in values of 0.67, 1.06, 0.56 and 1.05, 1.60, 0.95 for structural, operational, and overall conditions, respectively. As for the DBN model, values achieved for the year at which a pipeline would reach a certain condition state were close to the actual values from the validation dataset.

  • Spatiotemporal variability of road weather conditions and optimal RWIS
           density — an empirical investigation
    • Authors: Tae J. Kwon, Liping Fu
      Pages: 691 - 699
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      This paper presents a study aiming at understanding the relationship between the spatiotemporal characteristics of road weather conditions and a number of road weather information systems (RWIS) stations using real-world case studies. Semivariogram models are constructed to determine the spatial variability of road weather conditions, especially, autocorrelation range which describes a separation distance at which the measurements are no longer correlated to each other. An optimal RWIS density is then determined through an optimization process that minimizes the total inference errors across the underlying road network. The findings suggest that the regions with less varied topography tend to have a longer spatial correlation range than the regions with more varied topography. The study further reveals that the range of spatial autocorrelation is related to the optimal density of RWIS network — the region with a longer range requires fewer RWIS stations, than the region having a shorter range.

  • Development of an artificial neural network model to predict subgrade
           resilient modulus from continuous deflection testing
    • Authors: Omar Elbagalati, Mostafa A. Elseifi, Kevin Gaspard, Zhongjie Zhang
      Pages: 700 - 706
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      The subgrade resilient modulus is an important parameter in pavement analysis and design. However, available non-destructive testing devices such as the falling weight deflectometer (FWD) have limitations that prevent their widespread use at the network level. This study describes the development of a model that utilizes the rolling wheel deflectometer (RWD) measurements to predict the subgrade resilient modulus at the network level for flexible pavements. Measurements of RWD and FWD obtained from a testing program conducted in Louisiana were used to train an artificial neural network (ANN) based model. The ANN model was validated using data from a testing program independently conducted in Minnesota. The ANN model showed acceptable accuracy in both the development and validation phases with coefficients of determination of 0.73 and 0.72, respectively. Furthermore, the limits of agreement methodology showed that 95% of the differences between the subgrade resilient modulus calculated based on FWD and RWD measurements will not exceed the range of ±21 MPa (±3 ksi).

  • Diagnosis of partial blockage in water pipeline using support vector
           machine with fault-characteristic peaks in frequency domain
    • Authors: Dae Shik Kim, Sungho Shin, Go Bong Choi, Kwang Ho Jang, Jung Chul Suh, Jong Min Lee
      Pages: 707 - 714
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      Partial blockages in water pipe network can cause waste of energy and poor hygiene. Therefore, periodic diagnosis of water pipe state is necessary to maintain or replace blocked pipe when the blockage size is larger than a threshold. This work proposes a nondestructive diagnosis scheme that estimates the partial blockage in water pipe by classifying pressure signals in the frequency domain. Pressure data were collected with normal and two different fault states. A peak search algorithm is proposed to identify the ‘fault-characteristic’ peaks (FC-peaks) relevant for each blockage size. Support vector machine (SVM) classifier for each blockage was constructed with the FC-peaks as input. The SVM scores of different blockage sizes are used for diagnosis of partial blockage. The partial blockage can be diagnosed by comparing the SVM scores of different blockage sizes. The SVM classifier was able to successfully classify and diagnose three model pipes with normal state, moderate, and severe blockages.

  • Analysis of volumetric properties of bituminous mixtures using cellular
           phones and image processing techniques
    • Authors: Mohammed T. Obaidat, Khalid A. Ghuzlan, Mai M. Alawneh
      Pages: 715 - 726
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      This study aims to develop the microanalysis of the bituminous mixtures using cellular phone images (CPI) and image processing techniques (IPT). A new methodology and scheme was developed for faster and accurate procedure to compute volumetric design parameters; voids in mineral aggregate (VMA), voids in total mix (VTM), and voids filled with asphalt (VFA) using CPI and IPT instead of the conventional methods. Five types of cellular phones with different camera resolutions were used to analyze the horizontal cross section (face) of hot mix asphalt slices. A cellular phone digital mapping frame for microstructure of the bituminous mixture for data collection was designed and implemented. New models for computations of volumetric design perimeters (VMA, VTM, and VFA) were developed. Results showed that the best cellular phone for microanalysis of the bituminous mixture is type D, even though it does not have the highest resolution, and the best height of capturing the images is 35 cm.

  • Design philosophy and requirements of granular wear surface thickness for
           bridges subjected to extreme truck load
    • Authors: Fadi Oudah, Glen Norlander
      Pages: 727 - 735
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      With the increasing demand to build bridge systems to transport extremely heavy trucks in the mining industry, advancements in the current bridge design provisions are needed to account for the extraordinary weight and configuration of the mining trucks. There are no design provisions specifically developed to determine the granular wear surface thickness for haul road bridges. This research study proposed a design philosophy for bridge gravel wear surface design and developed a set of provisions for possible inclusion in international bridge and pavement codes. Three design requirements were developed, among which are two compulsory requirements and one optional requirement. The two compulsory design requirements include: maintain gravel cohesion, and prevent concrete deck cracking during the passage of the design vehicle. The optional design requirement is: minimize concrete deck cracking during the rare event of truck braking. Design recommendations and design aids pertaining to each design requirement were developed based on detailed analytical modeling.

  • Laboratory evaluation of the effect of styrene-butadiene-styrene –
           montmorillonite nanocomposite on rheological behavior of bitumen and
           performance of stone matrix asphalt mixtures
    • Authors: Rezvan Babagoli, Reza Mohammadi
      Pages: 736 - 742
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      This study was performed to evaluate moisture susceptibility of different stone matrix asphalt (SMA) mixtures modified with styrene-butadiene-styrene (SBS) and nanoclay. Different samples with various percentages of nanoclay (2, 3, 4, and 5%) and SBS (0 and 5%) based on the weight of the bitumen were prepared. Rheological and mechanical properties of the modified bitumen samples were also investigated using bitumen conventional evaluation tests and dynamic shear rheometer, respectively. Fourier transform infrared spectroscopy measurement was conducted for obtaining the microstructure distribution of modified asphalt binders. The chemical properties of aggregates were analyzed with X-ray fluorescence. Moisture susceptibility of the modified asphalt mixtures was evaluated using three different methods, including resilient modulus ratio, tensile strength ratio, and fracture energy ratio tests. Based on the obtained results, using nanoclay as the secondary modifier could improve mechanical properties of the SMA asphalt mixture.

  • An aggressive car-following model in the view of driving style
    • Authors: Fei Tan, Da Wei, Jianqi Zhu, Dong Xu, Kexin Yin
      Pages: 775 - 782
      Abstract: Canadian Journal of Civil Engineering, e-First Articles.
      The complexity of the driving behavior restricts the realism of traffic simulation. This paper proposed that vehicle mobility models should be established according to diverse driving styles to further approximation of real driving behavior. With Krauss model represented, the conservative (driving style) of safe distance car-following model is analyzed. The analysis means that real vehicles can occasionally break the safe distance rule, and on average, real vehicle gap is slightly smaller than that in the Krauss model. An aggressive car-following model is proposed in the view of driving style. Simulation results show the new model can simulate aggressive driving style, which has significance to simulate traffic using diverse driving style models. Since it breaks the safe distance rule, the new model has the possibility of generating rear-end collisions when simulating. Drivers’ characteristics, prediction behavior, the cause of accidents, and the effects of time granularity on a simulation are studied. The concept of “road black hole” is put forward, which is believed to reduce velocity of traffic flow.
