RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Design of Roller Compacted Concrete Pavements
This paper reviews some of the differences between roller compacted concrete and conventionally constructed concrete pavements. These differences require additional consideration during...
Treatment of Karst Along Tennessee Highways
The construction and maintenance of highways in karst areas of East Tennessee has resulted in the occurrence and treatment of induced sinkholes along the ditchlines of numerous highways....
Survivability and Durability of a Nonwoven Geotextile
This paper presents the results of a field investigation and laboratory testing program to evaluate the properties of two different polypropylene, thermally-bonded nonwoven geotextiles...
Pull-Out Response of Geotextiles and Geogrids (Synthesis of Available Experimental Data)
During the past 15 years, there has been a considerable growth in the use of various materials to reinforce soils. The rapid development of geosynthetics and their increasing use in soil...
Design of Ash Basin Dike across Cove
Embankments built over soft, unstable foundation materials had required that the materials either be removed or reinforced. With the introduction of geotextiles, it is now economically...
Low Permeability Liners Incorporating Fly Ash
This paper summarizes the results of a research study undertaken at West Virginia University to evaluate the feasibility of utilizing stabilized fly ash as a low permeability liner material....
Advanced Reconstruction for Subsidence-Damaged Homes
To address many of the residential damage-reconstruction problems from mine subsidence a research and development project was undertaken in Illinois. Phase I of this project is complete...
A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...
Recent Thoughts on Probabilistic Fatigue Crack Growth
We briefly review recent results of analysis of fatigue crack growth data. Implications of this analysis are presented, and reasons are advanced in favor of increasing the dimension of...
Modeling Fatigue Crack Growth Resistance, dN/da
In the fracture mechanics approach to fatigue, da/dN is correlated with the cyclic range of the stress intensity factor, ?K; the resulting relation, da/dN=f (?K), is commonly called the...
Stochastic Modeling of Fatigue Crack Growth
A new lognormal fatigue crack propagation model has been presented in which a two-dimensional state vector has been employed to introduce experimentally observed history dependence of...
Probabilistic Prediction of Mixed Mode Fracture Initiation and Trajectory Under Random Stresses
Methods are developed for estimating crack trajectory and the probability of crack initiation in mixed mode fracture. The analysis is based on a computer program for deterministic fracture...
Probabilistic Fatigue Crack Growth Analysis with Reliability Updating
A randomized fatigue crack growth model based on the Paris and Erdogan crack growth equation is used to estimate the reliability of fatigue sensitive details in steel bridges. This model...
Fracture Control for Arctic Vessels and Structures
Materials used for construction of Arctic structures and vessels are exposed to low ambient temperatures, high local ice loads and intermediate to high loading rates. All these factors...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Statistics of Concrete Shrinkage Test Data
The paper reports a large series of concrete shrinkage tests which can be used for statistical purposes. The series involves two groups of 36 identical cylindrical specimens, with a diameter...
Prediction of Concrete Creep and Shrinkage by Sampling on the Basis of Correlated Random Material Parameters
There are many random parameters which influence creep and shrinkage of concrete. In all of the previous probabilistic studies the parameters are assumed to be mutually independent random...
Reliability Based Analysis of Contact Problems
The S.B. Batdorf model is modified to include the reduction in shear due to the effect of compressive stresses on the crack face. This new formulation was used to obtain the probability...
Effects of Random Material Properties and Loads
The variability of slab deflections is estimated from analytical expressions accounting for random variations of spatially distributed loads and material properties (stiffness parameters)....
