Parameter Study of Stresses in Mass Concrete Using Two Fly Ash Mixtures
Finite-element modeling of the incremental construction procedure for mass concrete structures has been used to study the effects of three mechanical properties on thermal stresses. Material...
70 Year Performance Record for High Strength Structural Lightweight Concrete
The paper briefly discusses the first ship built using expanded aggregates manufactured in a rotary kiln the USS Selma. It then goes on to discuss achieving high strength concrete with...
Field Performance of Fiber Reinforced Concrete Highway Pavements
This paper reports the evaluation of field performance of fiber reinforced concrete pavements. The concrete was designed for a compressive strength of about 40 MPa. Steel fibers with hooked...
Montana's Approach to Reduce Asphalt Pavement Rutting
The Montana Department of Highways experienced premature rutting in some asphalt concrete pavements primarily on the east-west interstate in Eastern Montana. Montana participated with...
Effect of Lime on Asphalt Concrete Pavement Performance
In the early to mid 1980's, the Federal Highway Administration constructed 15 experimental field test sections in four states designed to investigate mitigating moisture damage...
Experimental Mixes to Minimize Rutting
This report describes the materials and construction details involved in the design and placement of four experimental mixes on I-95 (Richmond-Petersburg Turnpike) in 1985 and follows...
Concrete Pavement?Specification by Modeling
Concrete pavement specifications have traditionally been prescriptive with construction in-put defined. This practice does not include a definition of the product intended, restricts innovation,...
Curing Time for CRCP Mixtures Based on Flexural Strength
In this paper, the effect of different curing conditions on the flexural strength is investigated, and also the minimum required period for moist curing is found. The combined effect of...
Brittleness Index of Cementitious Composites
Series of direct tension tests were conducted to observe the softening response of different types of cementitious composites, namely, mortar, plain concrete, high strength concrete, normal...
Brittleness of High Strength Concrete
Fracture mechanics approaches are needed to determine material parameters which are related to the brittleness of concrete and its structural response. The size effect method is used to...
