Evaluation of a Large Aggregate Asphaltic Layer in an Airside Pavement
A new analytical method of designing large aggregate asphalt mixes (LAM) was used to design a thick asphalt base layer for an aircraft taxiway. The results of an analysis on the material...

Development of High Performnance Shotcrete (Theoretical Considerations)
This paper presents some theoretical considerations for studies on high performance wet-mix shotcrete. A new laboratory shotcrete pump and rheometer are being developed to study the effects...

Construction and Maintenance Decisions for Multi-Unit Deteriorating Facilities
Facilities that deteriorate over time and use can require maintenance or replacement. Selecting among replacement and maintenance alternatives for large systems of deteriorating facilities...

Aggregate Quarry Operations—From a Railroad's Perspective
This paper describes a study which shows how a railroad company can ensure receipt of a cost-effective, high-quality aggregate product for ballast by monitoring selected quarry operations....

Definition of a Weighting Function for Rainfall in Aggregated Rainfall-Runoff Models

Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...

Procedures for Evaluating Aggregate Gradation Specifications
The construction and rehabilitation of transportation facilities annually consumes huge quantities of aggregates. And, the variability in supply and demand for these materials as well...

Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....

Reliability-Based Design for Feeeze-Thaw Concrete
Observation of pavements in Iowa shows results from the test for freezing and thawing of concrete, ASTM C-666, is not always consistent with field performance. Similar concrete made with...

Producing Armourstone Within Aggregate Quarries
This paper discusses a series of full-scale trial blasts which was conducted in an aggregate producing quarry with the objective of improving yields of armourstone. The quantitative research...

RCC Mixes and Properties Using Poor Quality Materials–Concepcion Dam
This paper discusses aggregate studies, mix investigations, and material property tests for the relatively poor quality materials available for use in RCC at Concepcion Dam....

Passive Acoustic Emission for Quantitative Evaluation of Freeze Thaw and Alkali Aggregate Reaction in Concretes
Several experiments are reported in which the progression of freeze thaw (FT), alkali-aggregate reaction (AAR), and internal cracking caused by mechanical loading were monitored using...

Fracture Surface Characterization of Concrete
The objective of this paper is to characterize fracture surfaces of concrete, with varying maximum aggregate sizes dmax, by utilizing the concept...

Experimental Determination of the Relation Between the Damaged Zone and the Aggregate Size in Concrete Through Acoustic and Mechanical Techniques
The size of aggregates in concrete has an influence on the behavior of the material. The width of the localized band can be related to this characteristic. Different experimental techniques...
