The study area geographically covers up to 4207 km2. For evaluating the Water Quality Index (WQI), fourteen groundwater parameters were employed and the data was gathered for two decades (1972–1990 & 2010–2019). The groundwater parameters include TDS, pH, EC, TH, Ca2+, Mg2+, Na+, K+, CO3 2-, HCO3 - , NO3 - , Cl- , F- and SO4 2-. The weightage arithmetic approach was utilized to compute the WQI1 and all the parameters were spatially represented using Arc GIS 10.3 software. To compute the WQI2, the Sodium Absorption Ratio (SAR), Sodium Percentage (%Na), Residual Sodium Carbonate (RSC), Magnesium Hazard Ratio (MHR), Kelly's Ratio (KR), Permeability Index (PI) and Potential Salinity (PI) are employed. The hydro-geochemical features are statistically examined using the Piper trilinear diagram, Gibbs plot, correlation matrix and PCA biplot. The study results suggest that irrigation-and drinking-water quality is worsening from 2% to 44% of the studied region. Statistical analysis also yields satisfactory findings for both decades. According to the geochemical study, the anion and cation ranking for the 1972 decade is Mg2+> Ca+> Na+> K+=Cl- >HCO3 - ->CO3 2->SO4 2-, while the ranking for the 2019 decade is Na+> Mg2+> Ca+> K+=HCO3 - >Cl- >SO4 2->CO3 2->F- . The research indicates viable locations for drinking and irrigation reasons, while the low groundwater quality areas need effective treatment procedures before groundwater utilization.

The influence of several types of reinforcement on liquefaction resistance, such as polypropylene fibers, geofibers, cement and polypropylene fibers with cement is shown in this study. Cyclic stress-controlled triaxial tests and cyclic strain-controlled triaxial tests were performed on saturated samples with and without reinforcements under undrained conditions. Cemented specimens were prepared with cement contents ranging from 0% to 3% by weight of dry sand and then cured for 3 days. The lengths of polypropylene fibers are 10 mm and 20 mm, respectively. The fibers were mixed with dry sand– cement mixes containing 0.50% and 1.00% by weight, respectively. Geofiber specimens were prepared in various arrangements. It was found that the liquefaction improvement factor (LIF) increased when fiber content and fiber length increased. The addition of geofibers increased the liquefaction resistance, as the number of layers increased. The addition of 3%C+1%F provided the best liquefaction resistance in this study compared with other additives. Finally, the reinforcement with cement and fibers is crucial for liquefaction resistanceof bitumen mastic should be considered beside the asphalt mixture performance and the bitumen rheological behavior.

The existing research studies address the strength and permeability of pervious-concrete materials and only limited data is available on the microstructural characteristics of pervious concrete. In this study, a characteristic analysis was carried out at micro-and macrolevels to identify the behaviour of pervious concrete using three aggregate gradations. To attain the wide pore network in pervious concrete, fine aggregates were not added in mixes and metakaolin was added at 5% intervals up to 20% of cement. At the macro-level, strength, porosity and permeability were tested and at the micro-level, XRD, FTIR, SEM and EDAX analyses were used for pervious-concrete mixes with metakaolin. The maximum strength of pervious-concrete was achieved in a 4.75-9.5 mm size aggregate mix at 10% addition of metakaolin with cement. Micro-structural studies revealed that the addition of metakaolin significantly reduces anhydrous calcium hydroxide. A significant draining performance of more than 1 cm/s was attained in most of the pervious-concrete mixes due to high porosity and permeability. Hence, pervious concrete is considered as a sustainable alternative material that can address environmental problems.

Developing an effective method for gravel-road data collection allows both decision-makers and local agencies to efficiently obtain information regarding road conditions. In this study, a geographical information system (GIS)-based decision- support system was applied to assist local agencies in determining reliable access routes to all gravel roads in Wyoming. The routing criteria were developed using the Network Analyst tool of ArcGIS software based on the restrictions on average daily traffic (ADT) volume values, speed limits, driving distances and driving hours per day. Results indicated that the routing maps created by ArcGIS software were an easy-to-use method to plan and schedule data collection on gravel roads. The routing analysis provided a reliable means to minimize driving time and distance. The methodology developed in this study may be employed by local transportation agencies for road-maintenance purposes in rural areas.

The main objectives of this study are to model traffic road accidents, fatalities and injuries in Jordan, using different modeling techniques, including regression, artificial neural network (ANN) and autoregressive integrated moving average (ARIMA) models and to evaluate the safety impact of travel-restriction strategies during Covid-19 pandemic on trafficaccident statistics for the year 2020. To accomplish these objectives, data of traffic accidents, registered vehicles (REGV), population (POP) and economic gross domestic product (GDP) from 1995 through 2020 were obtained from related sources in Jordan. The analysis revealed that accidents, fatalities and injuries have an increasing trend in Jordan. Root mean of square error (RMSE), mean absolute error (MAE) and coefficient of multiple determination (R2) were sued to evaluate the performance of the developed prediction models. Based on model performance, the ANN models are the best, followed by the ARIMA models and then the regression models. Finally, it was concluded that the strategies undertaken by the government of Jordan to combat Covid-19, including complete and partial banning of travel, resulted in a considerable reduction of accidents, injuries and fatalities by about 35%, 37% and 50%, respectively.

Many correlations exist for faster prediction of soil engineering properties from its index properties, but correlations for quicker determination of the amount of clay mineral in the soil are still unexplored. This study focuses on determining the amount of clay mineral present in a soil sample rapidly by correlating claymineral percentages with soil index and chemical properties, which aids in selecting proper construction guidelines before undertaking construction work. Clay-soil samples collected from 20 different locations in Tamil Nadu state in India were subjected to chemical tests, like cation exchange capacity (CEC), specific surface area (SSA) and total potassium (TP), to quantify clay minerals such as kaolinite, illite and montmorillonite. Correlations were developed for kaolinite, illite and montmorillonite percentages in terms of chemical (CEC, SSA and TP) and index properties. It was observed that the montmorillonite percentage has shown a stronger correlation with soil index properties than illite and kaolinite percentages, because of its physico-chemical behaviour.

The objective of this paper is to study the feasibility of calcined bamboo leaf ash as a partial substitute to cement and its effect on compressive strength, pozzolanic activity, sorptivity and porosity characteristics in hardened concrete. Cement was replaced with BLA with a percentage of 10% to 30% with a uniform increment of 5%. Fallen dry bamboo leaves burnt in open atmosphere were heated in a muffle furnace for 4 hours at 500°C to induce pozzolanic activity. The grade of concrete was taken in such a way that it will give a characteristic compressive strength of 20 MPa. The chemical composition of BLA was obtained by XRF analysis. The nature of BLA was assessed by XRD analysis and found to have an amorphous structure. The pozzolanic activity was ensured by ASTM lime test (ASTM C311 and ASTM C109). Other durability characteristics, like sorptivity and porosity, were performed as per ASTM guidelines (ASTM C1545 and ASTM C127) to assess the resistance of BLA concrete against sorption and the volume of voids. From the experiments conducted, it was understood that cement could be replaced with BLA till 15% with a little compromise in strength and durability characteristics and that this replacement was found to be an optimum one.","PeriodicalId":51814,"journal":{"name":"Jordan Journal of Civil Engineering","volume":"10 1","pages":"279-289"},"PeriodicalIF":1.1,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66631418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
