A Notched Disk Crack Propagation Test for Asphalt Concrete
Cracking is a major distress in asphalt pavement which can lead to premature pavement failures and can cost agencies millions of dollars in maintenance and rehabilitation costs. Even with modern advances in pavement engineering, attempts to quantify and model cracking in asphalt pavements have proved extremely challenging; this is due to the visco-elastic behavior of asphalt concrete and the co...

متن کاملA Review of Adhesion Mechanisms at the Crack Sealant/asphalt Concrete Interface
Existing adhesion theories and associated mechanisms are reviewed and applied to bituminous crack sealants and to the crack sealing of asphalt concrete (AC) roadways. As such, the possible contribution of each mechanism to the sealant-interface-AC system is critically assessed. Of six possible adhesion mechanisms, only sealant adsorption and interlock can explain adhesion between sealant and AC...
متن کاملPart A- Experimental: Experimental Analysis of Crack Propagation in Pre-stressed Concrete Sleepers by Fracture Mechanics
This study investigates propagation of mode I crack in B70 pre-stressed concrete sleepers by fracture mechanics approach. A new experimental analysis is done for notched B70 pre-stressed concrete sleepers with Replica test and image analysis. A scanning electron microscope test (SEM) and an image analysis are applied for the Replica test in order to determine crack length and crack mouth openin...
متن کاملMonitoring of Crack Propagation in Concrete Using Embedded Piezoelectric Transducers
A concrete structure can be subject to several factors that may damage it during its service life. These factors are either be climatic, chemical or accidental. The security requirements are more and more speci c and severe. To ensure the safety of a structure, it is important to know its state and the properties of the materials that make it up. For this purpose, many tests has been developed....
