About this book

This book proposes the concept of a multi-layer pavement system to fulfill the blast resistance requirement for pavement design. It also presents a damage pattern chart for multi-layer pavement design and rapid repair after blast load. Such a multi-layer system consists of three layers including asphalt concrete (AC) reinforced with Geogrid (GST) at the top, a high-strength concrete (HSC) layer in the middle, and engineered cementitious composites (ECC) at the bottom. A series of large-scale laboratory impact tests were carried out to prove the usefulness of this concept and show its advantages over other conventional pavement system. Furthermore, field blast tests were conducted to show the actual behavior of this multi-layer pavement system subjected to blast load under real-world conditions.

Chapter 2. Development of New Multi-Layer Pavement System Subjected to Impact Load—Laboratory Large-Scale Drop Weight Test

The new multi-layer pavement system is proposed according to the laboratory impact test. This proposed multi-layer pavement is the combination of High Strength Concrete (HSC), Engineered Cementitious Composite (ECC), and Asphalt Concrete (AC) reinforced with High Strength Geosynthetics (GST), which has good impact resistance. The control specimens with current pavement design will also be investigated for its dynamic behavior under impact load. Results from conventional and proposed multi-layer pavement will be discussed.

Chapter 3. Development of New Multi-Layer Pavement System Subjected to Blast Load—Full Scale Field Blast Trial

The proposed multi-layer pavement system will be tested in the full scale field trial test to evaluate its resistance against blast load. The dynamic response of the proposed multi-layer pavement system under blast loading will be explored and analyzed.

Chapter 4. Property of Interface in the New Multi-layer Pavement System

The interface property among the multi-layer system usually plays an important role in the pavement performance subjected to impact and blast load. The direct and tilt table test will be conducted to determine the interface strength between AC and HSC layer. The numerical model of direct shear test will be developed and conducted to validate the parameters obtained from the laboratory test.

Chapter 5. Numerical Modeling of Pavement Slab Subjected to Blast Loading

The numerical analysis of the conventional pavement system and the proposed multi-layer pavement system under blast load will be conducted. The key results from numerical models will be discussed based on the parametric study for the proposed multi-layer pavement system. The design chart for proposed multi-layer pavement system under different blast energies will be further developed.
