Improving Road Pavement Characteristics: Applications of Industrial Waste and Finite Element Modeling

The book presents original technologies developed by the authors and existing Russian experience in study and application of technogenic raw materials (such as burnt rocks of mine dumps and ash-slag waste) to R&D of road constructions with high-strength properties and long-life operation . Another direction of the book is connected with finite-element modeling pavement constructions on different soils. To this aim, corresponding theoretical solutions and numerical algorithms are realized in ANSYS software. The obtained numerical results are compared with existing experimental data for real road constituents. It presents particular results of the Russian schools of Mechanics and Material Sciences not previously available outside of Russia.

Explains original theoretical and experimental methods developed for solution of the problems of effective using technogenic waste in building and road constructions;
Facilitates improvement and optimization of theoretical and numerical approaches for R&D of road pavements on different soils;
Describes new promising building materials based on easily accessible waste able effectively to replace conventional materials and supported by Russian patents.
