Moisture Controlled Water Pump Using Op-Amp
Abstract: Soil moisture monitoring framework is the blend of gadgets that can detect soil moisture, read or store information, and communicate the information back to the computer, which helps organise and understand the soil moisture information. Optimum plant development is primarily dependant on the proper water content in the soil. In order to boost the nature of yields and preserve water assets during irrigation, the soil moisture inspecting apparatus is created …

Contributing factors in the initiation of failure of asphalt concrete
Abstract: As long as the asphalt concrete pavement is under service, signs of failure usually initiate and the distress types start showing throughout the service life. The asphalt concrete pavement practices repeated tensile and shear stresses through the vehicular loading. In the present study, the contributing factors in the initiation of failure under repeated flexural stresses have been detected. Slab samples of Asphalt concrete have been prepared at the laboratory by …

Assessing the Durability of Stone Matrix Asphalt Concrete
Abstract: Stone Mastic Asphalt (SMA) is widely used throughout the world as one of the preferred asphalt surfacings. The local specifications define asphalt concrete durability based on maximum loads at failure. Therefore, it is required to assess the durability of the road surface materials of SMA and their ability to resist operational effects in terms of environmental impact. In this investigation, the durability of stone matrix asphalt concrete was assessed in …

Initiation of Distress in Asphalt Concrete After Practicing Moisture Damage
Abstract: The moisture damage of asphalt concrete is considered as major type of distress in heavy rainfall environment. In this work, the decline in the initial flexural stiffness of asphalt concrete was monitored after practicing the moisture damage process. The variations were analyzed relative to the control mixture. Asphalt concrete mixtures were created in the laboratory with the optimal binder content. Extra mixtures were also prepared with ±0.5% variation of binder …

IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …

Sustainability of Cold Recycled Mixture with High Reclaimed Asphalt Pavement Percentages
Abstract: The main goal of this study is to evaluate cold mixtures incorporating various percentages of reclaimed asphalt pavement (RAP) which is a typical sustainability technique to enhance the modern flexible pavement technology. The physical properties of RAP materials, new emulsion asphalt and new aggregate have been tested to evaluate the characteristics of these materials. Two mix design methods have been developed for control cold mix without RAP and recycled cold …

Assessing the Sensitivity of the Strength Properties of Asphalt Concrete Mixture to the Variation in Asphalt Binder Content
Abstract: The variationsin the asphalt cement binder content withinthe job mix formula, may exhibit a great influence on the required strength properties of asphalt concrete mixture. The present investigation deals with asphalt concrete mixtures which are usually implemented for wearing course pavement layer. The mixtures were prepared at optimum binder content of 4.8 %, and at ± 0.5 % of the optimum binder content and subjected to the short-term ageing process.Slab …

Effect of Energy/Protein Ratio and Strain on Performance, Nutrient Digestibility and Serum Biochemical Indices of Exotic and Locally Adapted Turkey
Abstract: This study investigated the response of locally adapted and exotic turkeys raised under the same environmental conditions to diets with varying energy/protein ratio. One hundred and fourty-four (144) four-week old poults of each strain of turkey were randomly selected and assigned to six different diets in a 2 x 2 x 3 factorial arrangement. Each treatment diet were replicated twice with twelve (12) birds per replicate. Diets formulated with 28 …

Determination of Bearing Strength Characteristics of Fine and Coarse Cohesive Soils from its Index Properties
Abstract: The variation in geology, cost and complexity in the preparation and testing for strength characteristics of soils from location to location has challenged geotechnical engineers to make optimum use of empirical formulas to predict bearing strength characteristics of soils. One major One major One major One major One major One major problem associated with bearing capacity of soil includes the different engineering properties associated with different geologic formations which have …
