Welcome to the “International Conference on Highway Pavements and Airfield Technology” of the Transportation & Development Institute (T&DI) of ASCE. This international conference will provide an unrivaled chance to interact and exchange information with worldwide leaders in the fields of highway and airport pavements, as well as airport safety technologies.
This conference will bring together researchers in transportation and airport safety technologies, designers, project/construction managers, academics, and contractors from around the world to discuss the state-of-the-art implementation, construction, design, and research being performed. The theme of the conference is “Sustainable Pavements and Safe Airports,” and will be dedicated to the state-of-the-art and state-of-practice areas of innovation, improved durability, cost-effective and more sustainable pavements and safety technologies to ensure safe and efficient airport operations today and into the future.

Alternative Types of Roundabouts: An Informational Guide
Author(s): Tomaž Tollazzi|Published By:Springer|Published Year:2015|Size: 21 MB|Quality:Original Preprint
This book presents a history of roundabouts, an introduction to their design, calculations of their capacity and traffic-safety features. It describes the key features of standard roundabouts and their limitations. Alternative types of roundabouts are a fairly recent development and have only been implemented in a few countries to date. The book illustrates a broad variety of these recent alternative types of roundabouts, as well as proposed types still in the development phase, explaining for each the specific needs it meets, its advantages and drawbacks. In closing, the book offers an outlook on the role of roundabouts in future street traffic.Table of contents : Front Matter....Pages i-xivOrigins of Roundabouts....Pages 1-9First Developments of Different Roundabout Types....Pages 11-56Modern Roundabouts Design....Pages 57-116Recent Alternative Types of Roundabouts....Pages 117-155Alternative Types of Roundabouts at Development Phases....Pages 157-169General Criteria for Calculating the Capacities of Alternative Types of Roundabouts....Pages 171-183Non-motorized Participants on Alternative Types of Roundabouts....Pages 185-199Possible Ways of Roundabouts’ Development....Pages 201-206

1.1 This European Standard establishes general principles for the execution of bored piles.
1.2 This European Standard applies to bored piles with:
— uniform cross-section (straight shaft);
— telescopically changing shaft dimensions;
— excavated base enlargements; or
— excavated shaft enlargements.
1.4 This European Standard applies to piles with the following rake (see Figure 4): — n ≥ 4 (Θ ≥ 76°); — n ≥ 3 (Θ ≥ 72°) for permanently cased piles.
1.5 This European Standard applies to bored piles with the following dimensions of the shaft or base enlargements (see Figure 3):
a) base enlargements:
1) in non-cohesive ground: DB / D ≤ 2;
2) in cohesive ground: DB / D ≤ 3;
b) shaft enlargements in any ground: DE / D ≤ 2;
c) slope of the enlargement in non-cohesive ground m ≥ 3; 1) in non-cohesive ground: m ≥ 3; 2) in cohesive ground: m ≥ 1,5;
d) base enlargements area of barrettes: A ≤ 15 m²;
1.6 The provisions of this European Standard apply to:
— single bored piles;
— bored pile groups;
— walls formed by piles.
1.7 The bored piles which are the subject of this European Standard can be excavated by continuous or discontinuous methods using support methods for stabilizing the excavation walls where required.
1.8 This European Standard applies only to construction methods that allow the designed cross-sections to be produced.
1.9 The provisions apply to bored piles constructed of:
— unreinforced (plain) concrete;
— reinforced concrete;
— concrete reinforced by means of special reinforcement such as steel tubes, steel sections or steel fibres;
— precast concrete (including prestressed concrete) elements or steel tubes where the annular gap between the element or tube and the ground is filled by concrete, cement or cement-bentonite grout.
1.10 Micropiles, mixed-in-place columns, columns constructed by jet grouting, ground improvement for piling, mixed-in-place pile bases and diaphragm walls are not covered by this European Standard.
