In order to overcome reflective cracks, different techniques have been developed in the past, the most important of which is the use of geosynthetic materials. It has been proven in many studies carried out in this field that using geosynthetics can delay reflective crack initiation and reduce the speed of propagation. In this research, a laboratory simulation was performed on the cracked pavement with five types of geosynthetics. Each type was tested by tensile force. According to the stress… 

Numerical Analysis of Leutner Shear Tests on Interface Between Geosynthetic and Asphalt Layers

Reflective cracks are the major distress in Hot-Mix Asphalt (HMA) Overlays. Among the several mitigation methods adopted to reduce the reflective cracking, the application of geosynthetic layer

Reflective Crack Propagation and Control in Asphalt Pavement Widening

To investigate the reflective crack-propagation behavior and provide control techniques for asphalt pavements widening, the finite-element models were built to simulate the widened asphalt pavement

Retarding premature reflective cracking in bituminous pavement using geosynthetics .

These cracks are developed as fatigue cracks (top down or bottom up cracking), longitudinal cracks and transverse cracks. One of the most challenging type of crack encountered is the development of

Evaluation of geocomposite-reinforced bituminous pavements with Amirkabir University Shear Field Test

Though geosynthetics materials have been proved effective in delaying reflective cracks, they cause a reduction in shear bonding between asphalt layers, reducing their efficiency and introducing new

Evaluation of the effective parameters on shear resistance of interface in a geocomposite-reinforced pavement

Abstract Application of geosynthetics is known as an important way to reduce and delay emergence of reflective cracks. However, reliance on these materials can have some disadvantages, including

Effect of geosynthetic reinforcement insertion on mechanical properties of hot and cold asphalt mixtures

The main objective of this research is to analyze the effect of the insertion of a geogrid reinforcement in the mechanical behavior of the hot mix asphalt (HMA) and the cold mix asphalt (CMA). For

Investigation of shear strength of interface between roadbase and geosynthetics using large-scale single-stage and multi-stage direct shear test

The application of geosynthetics in the road pavement industry as a reinforcement has increased dramatically in recent years. Geosynthetic inclusions can significantly: (i) increase the bearing

Developing a fatigue fracture model for asphalt overlay reinforced with geogrid

This study examines the influence of the most important parameters on delaying reflection cracking in geogrid reinforced overlay in bending mode, employing a large scale experimental set up. The



Using Pseudostrain Damage Theory to Characterize Reinforcing Benefits of Geosynthetic Materials in Asphalt Concrete Overlays

A methodology is described that was used to compare the relative effectiveness of six commercially available geosynthetic materials in reducing the severity or delaying the appearance of reflective cracking in HMA overlay, and grids and composites performed better than fabrics, which in turn performedbetter than a thin tacked surface as compared with unreinforced specimens.

Tests of HMA Overlays Using Geosynthetics to Reduce Reflection Cracking

The primary objective of this field phase of the research project was to evaluate geosynthetic products placed under or within hot mix asphalt overlays to reduce the severity or delay the appearance

Application of the wheel reflective cracking test for assessing geosynthetics in anti-reflection pavement cracking systems

The reflective cracking phenomenon occurs when joints and cracks in a pavement that is generally made of concrete or cement-treated layers propagate up through the asphalt overlay and appear on the

New Laboratory Equipment for Study of Reflective Cracking in Asphalt Overlays

One of the current road maintenance problems continues to be the appearance of reflective cracks in asphalt overlays. It would be of real benefit if laboratory equipment were available during the


ABSTRACT Asphalt concrete overlay on the existing pavement is often used as a cost-saving surface treatment for deteriorating pavements. A major problem encountered with asphalt resurfacing is the
