Hot mix asphalt has various benefits such as good workability and durability. It is one of the most general materials used mixtures in road pavements. Asphalt binders can be improved by modifying them with additives. Gilsonite a natural hydrocarbon which may an additive to hot asphalt. binder modifier (wet process) mixture (dry improve properties mix. provides option rheological properties, sta...

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 ...

The aim of this study is evaluating the interaction between several base pen grade asphalt binders (35/50, 50/70, 70/100, 160/220) and two different recycled plastics (EVA and HDPE), for a set of new polymer modified binders produced with different amounts of both recycled plastics. After analysing the results obtained for the several polymer modified binders evaluated in this study, including ...

Rutting of asphalt pavement occurs earlier and is more serious under the increasingly heavy traffic load conditions that can be found in subtropical monsoon climate regions. High modulus concrete (HMAC) with excellent anti-rutting anti-fatigue properties generally used to mitigate this issue. Given relatively high cost additives type asphalt, study feasibility using recycled mixture (RAP) Trini...

In the Mechanistic–Empirical Pavement Design Guide (MEPDG), dynamic modulus of asphalt mixes is used as one of the input parameters in pavement analysis and design. For in-service pavements, MEPDG method uses a combination of some field and laboratory tests for structural evaluation of asphalt layers in rehabilitation projects. In this study, ten new and rehabilitated in-service asphalt pavemen...

Asphaltic concrete for pavement construction in India are produced by using crushed stone, gravels etc. as aggregate. In north-Eastern region of India, there is a scarcity of stone aggregate. Therefore the road engineers are always in search of an optional material as aggregate which can replace the regularly used material. The purpose of this work was to evaluate the utilization of substandard...

Abstract This study intends to examine the effect of using bio-rejuvenators (BioCS and BitutechRAP) on Reclaimed Asphalt (RA) binder as seen from asphalt stiffness modulus (Sbit) based laboratory testing Dynamic Shear Rheometer (DSR) Frequency Sweep which is compared Sbit resulting analysis Van der Poel nomograph under RTFO (rolling thin film oven) conditions. The comparison was analyzed by loo...
