The cold in-place recycling (CIPR) is a process where the existing bituminous pavement is recycled without application of heat. In CIPR process the scarified material from the existing pavement is crushed to the required gradation and binder in cold form (emulsion or cutback or foamed bitumen) is added. Externally acquired Reclaimed Bituminous Pavement (RBP) or fresh aggregates are also added d...

Road construction is an important part of economic development, and the most pressing problem improving quality road surfaces. pavements are a combination mineral fillers bitumen, in which bitumen used as durable waterproof binder. Bitumen modification can improve by increasing plasticity interval, adhesion to metal materials, resistance aging, expanding operating temperature range. Softening p...

Tar bitumens are increasingly being used as a binder in road works. They consist of a standard product of about 70% bitumen and 25-30% tar. Tar bitumens are classifiable as the pyrolysis products of organic materials and are applied hot. Depending on the temperature used there are emissions of various intensities of polycyclic aromatic hydrocarbons (PAH), some of which are carcinogenic. A total...

• Molecular pull-off simulation of bitumen-aggregate interface was performed. Cohesive debonding percentage rises with bitumen film thickness and temperature. Less cohesive more adhesive occur at higher velocities. Stronger alkaline minerals are prone to have debonding. When an asphalt mixture cracks, occurs along bitumen-mineral interfaces within films. At microscale, the two processes can hap...

Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...

Nowadays, the use of reclaimed asphalt pavements (RAP) is often combined with Warm Mix Asphalt (WMA) technologies with several benefits in terms of environment, cost and mechanical performance. Concerns still exist related to in-service and aging characteristics of warm recycled mixtures since WMA technologies have been developed over the last decade and hence long term performance data are not...
