Asphalt Mixture Selection Free PDF

This practical guide starts with a survey of the types of site and the asphalt properties which are required. Various external influences which may affect the relative importance of some properties are addressed, and the interplay of sites and external is considered. Asphalt mixture types and their properties are reviewed, largely as defined in the EN 13108 series but subdivided into further categories, and into maximum nominal coarse aggregate sizes using EN 13043 basic set plus set 2 sizes.

Guidance is given, including using flowcharts, of the different mixtures that are suitable for each situation. In some cases a range of choices or mixtures with different degrees of suitability is offered. The guidance covers surface course, binder course and base, but with more focus on the surface course where the external influence is most significant. The site and external influence combinations on which a mixture can be used successfully are also given.

The book is primarily intended for those who select asphalt on an occasional basis, such as architects or housing developers, but could be of use to other engineers with limited experience. It is also useful as an educational textbook for those studying asphalt technology.

Geotechnical Engineering Rule of Thumb – Rajapakse – Free PDF

“Geotechnical Engineering Calculations and Rules of Thumb, Second Edition, offers geotechnical, civil and structural engineers a concise, easy-to-understand approach to selecting the right formula and solving even most difficult calculations in geotechnical engineering.

A “quick look up guide”, this book places formulas and calculations at the reader’s finger tips. In this book, theories are explained in a “nutshell” and then the calculation is presented and solved in an illustrated, step-by-step fashion.

In its first part, the book covers the fundamentals of Geotechnical Engineering: Soil investigation, condition and theoretical concepts. In the second part it addresses Shallow Foundations, including bearing capacity, elastic settlement, foundation reinforcement, grillage design, footings, geogrids, tie and grade beams, and drainage.

This session ends with a chapter on selecting foundation types. The next part covers Earth Retaining Structures and contains chapters on its basic concepts and types, gabion walls and reinforced earth walls.

The following part covers Geotechnical Engineering Strategies providing coverage of softwares, instrumentation, excavations, raft design, rock mechanics, dip angle and strike, rock stabilization equipment, soil anchors, tunnel design, seismology, geosynthetics, and slurry cutoff walls.

The final part is on Pile Foundations including content on design on sandy soils, clay soils, pin piles, negative skin friction, caissons and pile clusters. In this new and updated edition the author has incorporated new software calculation tools, current techniques for foundation design, liquefaction information, seismic studies, laboratory soil tests, geophysical techniques, new concepts for foundation design and Dam designs.

All calculations have been updated to most current material characteristics available in the market. Practicing Geotechnical, Civil and Structural Engineers may find in this book an excellent companion to their day-to day work, benefiting from the clear and direct calculations, examples, and cases.

Advanced Soil Mechanics – Braja.Das – Free PDF

Soils are aggregates of mineral particles, and together with air and/or water in the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress.

This book is divided into eight chapters—“Soil aggregate, plasticity, and classification,” “Stresses and strains—elastic equilibrium,” “Stresses and displacement in a soil mass,” “Pore water pressure due to undrained loading,” “Permeability and seepage,” “Consolidation,” “Shear strength of soils,” and “Settlement of foundations.”

An Introduction to Geotechnical Engineering – Holtz & Kovacs Free PDF

An Introduction to Geotechnical Engineering is intended for use in the first of two-course sequence in geotechnical engineering usually taught to third- and fourth-year ungraduate Civil Engineering students.

We assume that students have a working knowlege of ungraduate mechanics, especially statics and mechanics of materials (including fluids).

A knowledge of basic geology, although helpful, is not essential. We introduce the « language » of geotechnical engineering in the first course, that is, the classification and engineering properties of soils.

Once the student have a working knowledge of how soil behaves as an engineering material, he/she can begin to predict soil behavior, and in the second course , to carry out the design of simple foundations and earthquake systems.

Structural And Stress Analysis – Fourth Edition Free PDF

By T.H.G. Megson

The purpose of this book is to provide, in a unified form, a text covering the associated topics of structural and stress analysis for students of civil engineering during the first two years of their degree course.

The book is also intended for students studying for Higher National Diplomas, Higher National Certificates, and related courses in civil engineering.

Frequently, textbooks on these topics concentrate on structural analysis or stress analysis, and often they are lectured as two separate courses. There is, however, a degree of overlap between the two subjects and, moreover, they are closely related.

In this book, therefore, they are presented in a unified form which illustrates their interdependence. This is particularly important at the first-year level where there is a tendency for students to ‘compartmentalize’ subjects so that an overall appreciation of the subject is lost.

Construction Cost Management – Learning From Case Stadies Free PDF

There have been many significant changes in the construction sector within the past decade. Notably, the sector has witnessed the growth of partnering and alliancing which require better management of the supply chain and increasing use of the NEC Contract (NEC3) which requires a team-based proactive approach to project delivery.

New financial models have been developed including Private Finance Initiative (PFI), Local Asset Backed Vehicles (LABVs), and variants of these in which private sector consortia design, build, own, and operate public facilities in partnership with the public sector.

Great advances have been made on the technical front with the growth of Building Information.

Content :

Introduction
Management of the Pre-contract Stage
Key Tools and Techniques
Procurement Strategies
Management of the Post-contract Stage

Hollow Structural Section – Connections And Trusses Free PDF

Rectangular hollow section (RHS) trusses can be formed by welding together single- or double-miter cut RHS web members and RHS chords. Web members may either be gapped or overlapped at the chord face.

Overlapped connections (or joints) are stiffer and stronger than gapped connections, but both are considered to be “semi-rigid” (neither pinned nor rigid).

Lack of connection rigidity is well-known to affect the force distribution and deflections in RHS trusses

Content :

1. Introduction
2. Previous truss tests
3. Truss test program
4. RHS truss models
5. Evaluation of truss models
6. Comments on CSA S16-14 and additional recommendations
7. Conclusions

Cable Supported Bridges – Concept And Design Free PDF

The decision to prepare a manuscript for a book titled CABLE SUPPORTED BRIDGES was taken by Niels J. Gimsing in 1980 following his three-year affiliation as an adviser on bridge technology to Statsbroen Store Bœlt—the client organization established to design and construct a bridge across Storebælt (Great Belt) in Denmark.

During the design period from 1976 to 1979, a large number of different designs for cable-stayed bridges (with spans up to 850 m) and suspension bridges (with spans up to 1800 m) were thoroughly investigated and it was during that period the idea matured to write a book covering both cable-stayed bridges and suspension bridges.

The chance to prepare the manuscript came in 1979 when the Danish Government decided to postpone the construction of the Storebælt Bridge and to keep the design work at rest for a period of five years.

1 Evolution of Cable Supported Bridges
2 Cables
3 Cable System
4 Deck (Stiffening Girder)
5 Pylons
6 Cable Anchorage and Connection
7 Erection
8 Aerodynamics
