Use of epoxy asphalt as surfacing and tack coat material for roadway pavements

This work presents an experimental program developed to evaluate the effect of epoxy-asphalt binder, used as replacement of bitumen, on the durability and fatigue life of an asphalt concrete mix. The use of epoxy-type binder as tack coat has been explored as well and thus experiments have been conducted to quantify the effect of epoxy tack coat...

Effect of printing parameters on interlayer bond strength of 3D printed limestone-calcined clay-based cementitious materials: An experimental and numerical study

For a single batch material, time intervals and nozzle standoff distances between two subsequent layers are two critical printing parameters that influence the mechanical performance of the printed concrete. This paper presents an experimental and numerical study to investigate the impacts of these printing parameters on the interlayer bond...

A re-study of the Atocha memorial in Madrid using dry-stacked interlocking cast glass components

Structures made from cast glass components are transparent and make full use of the high compressive strength of glass. As they have more freedom in shapes and can therefore be designed with a large cross-section, it is more suitable as a<br/>structural element than fl oat glass. However, most cast glass structures that have been completed...

The Stackable Glass Column

In 1942 cast glass columns weredesigned in the Danteum by GiuseppeTerragni. But due to the annealing timeof large glass pieces, these have neverbeen produced. Now, more than 75years later, a new type of cast glasscolumn will be designed. This time, thedesign is made out of interlocking drystacked cast glass components.Glass is a strong yet...

Determination of mechanical properties and water susceptibility of low-noise road surfaces

Nowadays, there is a need to reduce noise pollution due to the tyre-pavement interaction, especially in densely-populated areas, such as the Netherlands, where noise pollution is a major concern. A solution to this problem is the development of pavement surfaces with improved noise reduction characteristics. Previous attempts to develop low...

Structural Aspects of an Arched Glass Masonry Bridge

The glass group of the TU Delft plans to realize a 14m span glass arched masonry bridge, yet no prescriptions are available on how to assess the structural safety of such a structure. Regulations and guidelines for structural glass relate to float glass elements and do not refer to structures of cast glass elements. In addition, to display the...

Welding of thermoplastic to thermoset composites through a thermoplastic interlayer

Research into the fusion bonding of joints containing thermoplastic and/or thermoset composites. A thermoplastic interlayer is co-cured with the thermoset that provides a fusible surface. Depending on the type of materials the interlayer can form an adhesive interface or a gradient interphase with the thermoset. Welding of thermoset composite to...

Swimming pools of glass

In projects involving swimming pools with structural glass, ABT Consulting Engineers has faced similar design requirements: maximal transparency, proper detailing, 100% water tightness and robust behavior. ABT developed a straightforward detailing to satisfy these requirements. The concept is applied in the glass swimming pool of the 900 Mahler...

Fragile yet Ductile: Structural Aspects of Reinforced Glass Beams

This dissertation investigates the structural aspects of reinforced glass beams. The concept of these beams, which are intended for building applications, is to provide redundancy even if the glass is broken. This redundancy is obtained through a small reinforcement section that is bonded at the tensile edge of the glass beam. Upon glass failure...

Experimental investigation of the temperature effect on the structural response of SG-laminated reinforced glass beams

Structural Glass Beams with Embedded Glass Fibre Reinforcement

This paper investigates the possibilities of pultruded glass fibre rods as embedded reinforcement in SentryGlas (SG) laminated glass beams. To do so, a series of pullout tests, to investigate the bond strength of the rods to the laminate, and a series of beam tests, to investigate the post-breakage response of the beams, have been performed....
