Abstract

There has been significant research progress in the area of pavement materials and paving technologies in the past decade. This includes the use of warm mix asphalt technologies, rubber asphalt, bio asphalt, nanomaterial applications, new construction technologies, innovative concrete materials, as well as the application of mechanistic–empirical pavement design. With all these developments, a collection of peer-reviewed articles with the theme of advanced asphalt materials and paving technologies is necessary for industry, researchers, government agencies, and other stakeholders. This collection promotes new technology, low costs, high durability, environmental friendliness, and effective resource usage in the area of advanced asphalt materials and paving technologies.

Abstract

Experiments to characterize the effects of moisture content and temperature on the mechanical properties of concrete were conducted. Based on these experiments, a new overall material model capable of predicting the mechanical behaviour of concrete subject to elevated temperatures up to 100 °C was developed. The material model estimates the time, temperature and moisture dependency of the compressive and tensile strength, creep and shrinkage of concrete.

Abstract

While the present state of knowledge on the time dependent deformation behaviour of normal and high-strength concrete may be considered as sufficiently determined, the creep and shrinkage of lightweight aggregate (LWA) concrete, particularly of high-strength LWA concrete, can only be specified inadequately. On the basis of the experimental results a prediction model for shrinkage and creep of structural lightweight aggregate concrete was developed.

Abstract

Several experimental campaigns are conducted to find feasible fiber reinforcements for buildings under earthquake conditions. Therefore tensile tests for the description of the bonding behavior of the fibers, shear tests on three-stone small specimen, small static cyclic shear wall tests, bending tests of wall segments, large format dynamically loaded wall plates and five building experiments were performed under realistic time history acceleration. At the end a calculation method is proposed.

Abstract

Concrete is widely used because of its versatility, affordability, and availability of raw materials, strength, and durability. Urban development that took place through the world in the last few decades yielded significant developments for concrete technology. The term high-performance concrete (HPC) is relatively new, and it refers to many properties such as strength, durability, sound and heat insulation, waterproofing, and side advantages such as air purification, self-cleaning, etc. Researchers and engineers are constantly working for improving concrete properties. This book provides the state of the art on recent progress in the high-performance concrete applications written by researchers and experts of the field. The book should be useful to graduate students, researchers, and practicing engineers in related fields.

Abstract

Hydraulic structures are exposed to multifaceted exposures. Particular the hydro-abrasive wear of the concrete edge zones represents a key exposure. The knowledge about the abrasive mechanisms of concrete and its degradation process is still insufficient. Relating to the hydro-abrasive test method, the relevant material parameter and degradation model incomplete knowledge existed which was removed.

Abstract

The reason for this research are the differences of the bond stress-slip relationships between pullout, push-in and tension tie specimen. A general admitted bond stress-slip law is developed which bases upon analytical consideration. The new developed bond stress-slip law considers the three-dimensional stress state of concrete in front of the rib of the reinforcing bar.

Abstract

This work deals with the experimental , static - cyclic testing of large-scale tests on walls made from hollow blocks. Based on this non-linear finite element models are developed and verified using the extensive experimental data ,whereby a semi - empirical design concept could finally be derived for hollow concrete masonry walls by a parametric study .
