Performance Evaluation Of Bamboo Reinforced Concrete Beams
(Civil & Environmental Engineering, 2007-08-23)
This study presents the evaluation of the feasibility of the use of bamboo as a potential reinforcement in concrete structural members. To achieve this objective a series of tensile tests on three types of bamboo Solid; ...
Studies On Volume Change Movements In High PI Clays For Better Design Of Low Volume Pavements
(Civil & Environmental Engineering, 2008-09-17)
Numerous low- to medium-volume roads such as Farm Market (FM) roads constructed on expansive clay subgrades, especially in the eastern and central Texas, encounter severe pavement cracking and premature loss of serviceability. ...
Characterization Of Cemented And Fiber-reinforced RAP Aggregate Materials For Base/ Sub-base Applications
(Civil & Environmental Engineering, 2007-08-23)
The engineering product known as RAP is a bonded base and sub-base material produced by the process of blending crushed recycled construction and demolition waste and debris to specified gradation requirements, and by ...
A Comprehensive Study Of Recycled Concrete Aggregates As A Drainable Base Layer For Pavements
(Civil & Environmental Engineering, 2009-09-16)
The use of recycled materials in construction is becoming increasingly popular due to the shortage of raw materials. Coupled with the environmental concerns surrounding the quarrying of natural minerals, waste materials ...
Subsurface Investigations Using High Resolution Resistivity
(Civil & Environmental Engineering, 2008-09-17)
Electrical resistivity imaging has been proved to be well suited to produce images of subsurface conditionsbecause of the ability of the technique for detecting resistive features and discriminating subtle resistivity ...
Autotrophic Denitrification Of Groundwater In A Granular Sulfur-packed Up-flow Reactor
(Civil & Environmental Engineering, 2007-09-17)
Autotrophic denitrification is an effective treatment technique for nitrate removal from groundwater. Six basic elements are required for the growth of autotrophic denitrifiers: (1) electron donor, (2) electron acceptor, ...
Effects Of Water-cement Ratio On Deep Mixing Treated Expansive Clay Characteristics
(Civil & Environmental Engineering, 2007-08-23)
The structures built on the unstabilized expansive soils are subjected to distress due to swell shrink behavior due to seasonal fluctuations. Medium stiff expansive clays with moderate and high PI were collected from two ...
Comparison Of Clinoptilolite With Gravel In A Recirculating Course Media Biofilter Treating Simulated Septic Tank Effluent
(Civil & Environmental Engineering, 2007-08-23)
The main objective of the pilot scale study was to compare the performance of recirulating clinoptilolite biofilter with course gravel biofilter used to treat simulated septic tank effluent by simultaneous nitrification ...
Assessment Of Soil-water Retention Properties Of Lime And Cement Treated Clays
(Civil & Environmental Engineering, 2007-08-23)
The soil-water characteristic curve (SWCC) of unsaturated soils has considerable importance in the analysis of geotechnical engineering problems involving soils that remain under partially saturated conditions throughout ...
Comparative Damage Of Different Truck Configurations On Jointed Plain Concrete Pavement
(Civil & Environmental Engineering, 2009-09-16)
This study estimated the damage done by trucks with 35 different configurations on a typical structure of a Jointed Plain Concrete Pavement. The configurations were proposed by New York Department of Transportation, the ...
