Good Concrete Mix Design

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. Good Concrete Mix Design: •Understand requirements of the concrete. •Identify if an existing mix may...

Steel Fibre Reinforced Concrete for Industrial slab on ground pavements

Industrial Members Only

The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Royce Ratcliffe covers: Fibres vs conventional reinforcement Testing of fibres How fibres increase load carrying capacity...

Properties of Fibre Concrete for Industrial Pavements – Synthetic Macro Fibres

Industrial Members Only

The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Ryan Pearce covers: Issues discussed; traditional methods of drying shrinkage crack control, different types of fibre...

Design Methodology for Load Transfer at Joints in Industrial Concrete Slabs and Pavements

Industrial Members Only

The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Bruce Ireland covers: Minimum requirements for selecting load transfer dowels in industrial pavement design are discussed...

Concrete Requirements For Industrial Pavements

Industrial Members Only

The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This presentation by Daksh Baweja covers: Presentation addresses internal industrial/factory floors. Discusses Guides Specifications Standards for concrete and cement,...

Plastic Shrinkage Cracking Spreadsheet to calculate evaporation rates of bleed water from concrete surfaces

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

This document is a simple Excel spreadsheet which allows the user to input Air Temperature, Concrete Temperature, Relative Humidity & Wind Velocity to determine the Bleed Water Evaporation Rate. The formulae, developed by P Uno, are based on the well known ACI Bleed Water Evaporation Nomograph.

Concrete Pavement Design, Construction & Performance

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

The ACI has released a new publication "Concrete Pavement Design, Construction and Performance written by Norbert Delatte. It is available through the ACI at www.concrete.org - go to their bookstore. "A pavement project may be envisioned as a three link chain, consisting of materials, design, and construction. Because the weakest...

Flatness and Levelness of Concrete Pavements for Industrial Areas Requirements and Evaluation Methods

Industrial Members Only

Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors; these structures, in many cases, present the same technical problems of road pavements. Characteristics, construction techniques, exercise conditions, maintenance and control of industrial pavements, in effect, are very similar to the ones usually...

Surface Stresses of Thick Concrete Pavement Slabs Due To Traffic Loads and Non-Linear Temperature Distributions

Airports, Highways, Industrial, Intermodals/Ports Members Only

In this study, possibility of top-down cracking in concrete pavement was investigated. The main cause of the crack is supposed to be tensile stress at the top of the concrete slab. 3DFEM simulations that took into account actual temperature distributions throughout slab depth were performed on concrete pavements for a...

Structural Modeling of Rigid Pavement with Load-rate Dependent Subgrade

Highways, Industrial Members Only

It has been observed by many researchers that the subgrade behavior is load rate dependent. The apparent subgrade stiffness is much higher under the fast moving axle loading than during the slow developing temperature curling and moisture warping. However, traditionally a single k-value is used for both curling and axle...

Effect of Nonuniform Foundation Support on Concrete Slab Responses

Airports, Highways, Industrial, Local Government Members Only

The ability to spatially map the stiffness of the foundation layers under concrete pavements with intelligent compaction has created a need to define limits on the allowable stiffness variations in a given construction area as well as the maximum size of a non-complaint area which does not require remedial action....

Performance of Pervious Concrete Pavement in Freeze-Thaw Conditions and With Winter Maintenance [No Fines Concrete]

Highways, Industrial, Local Government Members Only

In 2007 the Cement Association of Canada, industry members and the Centre for Pavement and Transportation Technology at the University of Waterloo partnered to carry out a study to evaluate the behaviour of pervious concrete pavement in the Canadian climate. Field sites have been constructed and monitored and laboratory testing...
