Performance Studies On Rigid Pavement Sections Built On Stabilized Sulfate Soils
(Civil & Environmental Engineering, 2007-08-23)
Soils of Southeast Arlington are highly expansive and rich in sulfates. They undergo sulfate induced heaving when traditional calcium based stabilizers are used for soil stabilization (Puppala et al. 1998). Traditional ...
Performance And Check-out Verification Testing Of A New True Triaxial Apparatus Using Partially Saturated Silty Sand
(Civil & Environmental Engineering, 2007-08-23)
A stress-controlled, flexible boundary, true triaxial (cubical) testing apparatus has been developed to test 3-inch cubical specimen of partially saturated soil under different moisture contents and for a wide range of ...
Experimental Studies To Address Strengths Of Limestone Cores, Sulfate Heave Problems In Limestone Cores And Tunnel Lining
(Civil & Environmental Engineering, 2007-08-23)
Sulfate induced heave is a common scenario in tunnels located on sedimentary rocks containing Pyrites. Pyrite oxidation produces Gypsum which is a major source of natural sulfates. DART NC -1B tunnel is located in Dallas, ...
Water Damage Evaluation Of Concrete Infrastructure
(Civil & Environmental Engineering, 2007-08-23)
This study presents an experimental program to evaluate the effect of a special waterproofing material, International Chem-Crete Pavix (CCP), on the durability of concrete. The experimental program identified the concrete ...
Numerical Modeling And Analysis Of Pile Supported Embankments
(Civil & Environmental Engineering, 2007-08-23)
Very soft clays are often avoided in construction due to their low shear strength and high compressibility. Special construction methods are adopted when embankments are constructed on very soft clay or peat. Design of ...
Evaluation Of Resilient Modulus Of Cement And Cement-fiber Treated Reclaimed Asphalt Pavement (RAP) Aggregates
(Civil & Environmental Engineering, 2007-08-23)
Natural aggregates derived from a variety of source rocks have been used as a road base material. But the extraction of natural aggregates resources is increasingly being constrained by urbanization, increased costs and ...
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; ...
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 ...
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 ...
