Fundamental understanding of micro-mechanical behaviors in bitumen, including phase separation, micro-friction, micro-abrasion, etc., can help the pavement engineers better understand the bitumen mechanical performances at macroscale. Recent researches show that the microstructure evolution in bitumen will directly affect its surface structure and micro-mechanical performance. In this study, th...

This study aims to determine Marshall's characteristics using asphalt binder modified polymer AC 50/70 (Starbit E-55) local Bantak material. The test method used is a hot mix (Hot Mix) with the Marshall method. content was 5% successively; 5.5%; 6%; 6.5%; and 7% consisting of 3 specimens for each variant. research carried out at Material Laboratory Department Civil Engineering Planning, Faculty...

Nanomaterials exhibit novel properties and profound attributes as an additive in asphalt binder modification. However, the application of nano-silica binders mixture modification is still limited, further research required. Along these lines, this work, with a content from 2% to 8% increment was utilized modifying bitumen type C320, which considered most conventional used Western Australia road...

The main objective of this study was to assess the performance and physical properties hot mix asphalt mixes incorporating recycled aggregates from demolished concrete compare them with an unmodified mixture. Using offers potential environmental benefits by reducing load on landfill sites associated waste. Hot were prepared using Marshall mix-design technique, varying proportions (0%, 25%, 50%,...

The article presents the results of research on production polymer-bitumen binder (PBB) based mixtures non-oxidized and oxidized petroleum products, namely high-viscosity tar, darkened vacuum distillate, bitumen 70/100, obtained at technological installations Limited Liability Partnership (LLP) “JV Caspi Bitum’’ styrene-butadiene-styrene (SBS) block copolymer brand L 30-01A modifier in presence...

Today, rapid economic and industrial growth generates increasing amounts of waste materials such as waste tyre rubber. Attempts to inspire a green technology which is more environmentally friendly that can produce economic value are a major consideration in the utilization of waste materials. The aim of this study is to evaluate the effect of waste tyre rubber (crumb rubber modifier (CRM)), in ...
