Principles of Pavement Engineering, 2nd edition builds on the previous edition, expanding on the fundamental principles of pavement engineering, concentrating on an understanding of the behaviour of pavement materials and of the real meaning of tests carried out on those materials. It includes necessary updates, such as: warm-mix asphalt, as it is increasingly environmentally attractive; cold-mix asphalt; asphalt recycling; bridge deck surfacing; design against potholes; treatment of Stress Absorbing Membrane Interlayers; surface treatments; pavement edge issues; and parking areas. This book also covers soils, granular materials and hydraulically-bound materials (including concrete), and will explain the various relevant engineering properties of those materials and how they are affected by such matters as compaction, water content, binder content etc.

This book is essentially a scientific study of relationship between languages, leading to a synthesis between the evidence of comparative linguistics and that of history, archaeology and genetics. It is based on an evaluation of the mathematics of language change and the logical deductions that can be made once a sound mathematical representation has been formulated. The methodology used is quite different from any standard linguistic approach and in many respects is much less definite in its detail, yet much more far- reaching with respect to the passage of time. The result is a set of conclusions based on linguistic comparison that accords well with deductions based on other disciplines, implying that the methodology used is appropriate despite its lack of precision. Conclusions are then drawn relating to several contentious issues, including for example the colonisation of America, the root of Chinese civilisation, the origin of Basque, the location of the original Indo-European 'homeland', and the genetic relatives of the Caucasian language families.
