Design and Resistance Factor Calibration of Pipe Piles in California
(2016-05-11)Steel pipe piles, either open ended or close ended, are widely used in the state of California as bridge foundations due to high load bearing capacity, light weight, and outstanding workability. The design methods currently ... -
Design Of Controlled Low Strength Material For Bedding And Backfilling Using High Plasticity Clay
(Civil & Environmental Engineering, 2013-03-20)Flowable fill or Controlled Low Strength Material (CLSM) is a self-compacted cementitious material used in the field in the place of compacted fill. It is also known as unshrinkable fill, controlled density fill, flowable ... -
Design of Crack Attenuating Mix using Waste Plastic
(2022-08-10)Plastic has many good properties such as inexpensiveness, light weightedness and durability, but it comes with one major catch i.e., its ‘indestructibility’. Plastic waste is now omnipresent and highlights that all plastic ... -
Design Of Short Drilled Shaft Foundations In High-plasticity Clay Under Inclined Loading
(Civil & Environmental Engineering, 2011-07-14)Drilled shaft foundations are primarily used to support structures such as bridge piers, towers, buildings, transmission towers, and roadway cable barriers. Generally, the main characteristics of drilled shafts are to ... -
Determination Of Geotechnical Properties Of Clayey Soil From Resistivity Imaging (RI)
(Civil & Environmental Engineering, 2011-10-11)The use of resistivity imaging (RI) in the subsurface investigation has increased in recent years. RI is a non destructive method and provides a continuous image of the subsurface. Based on the electrical conduction ... -
DETERMINATION OF ROOT LENGTH OF EVAPOTRANSPIRATION COVER USING ELECTRICAL RESISTIVITY IMAGING TECHNIQUE
(2018-05-01)Evapotranspiration (ET) covers are receiving an increasing amount of attention for use at waste disposal sites. Instead of using barrier layers like conventional covers, percolation in ET cover system is minimized by water ... -
Determination Of Safe Buffer Width Of Roadway To Protect Human Health Form Harmful NOx Exposure
(Civil & Environmental Engineering, 2007-08-23)According to the 2004 EPA Trends Report, US on-road transportation sources emit 36% of nitrogen oxides (NOx), 63% of carbon monoxide (CO), and 29% of volatile organic compounds (VOCs). This research determines a safe roadway ... -
Determining The Effectiveness Of Chlorine-based Biofilm Control On The Friction Factors Of Large Diameter Pipelines In Raw Water
(Civil & Environmental Engineering, 2013-03-20)Large diameter transmission mains pumping raw water experience capacity loss during the summer months due to the growth of biofilm. The loss of capacity impacts power costs at a time when power is obtained at a premium. ... -
