2014年5月1日 · Some popular plastomers and thermoplastic elastomers in bitumen modification are discussed regarding their advantages and disadvantages, including polyethylene (PE), polypropylene (PP), ethylene–vinyl acetate (EVA), ethylene–butyl acrylate (EBA), styrene–butadiene–styrene (SBS), styrene–isoprene–styrene (SIS) and styrene–ethylene/butylene–styren...

Polymer modified bitumen (PMB) is one of the specially designed and engineered bitumen grades that are used in making pavement, roads for heavy duty traffic and home roofing solutions to withstand extreme weather conditions. PMB is a normal bitumen with the added polymer, which gives it extra strength, high cohesiveness and resistance to ...

2011年1月1日 · One of the many methods employed to toughen bitumen is to blend it with polymers, either virgin or scrap, to produce polymer modified bitumen (PmB). In this chapter, an introduction to bitumen structure and properties, and a short review of the published literature on PmB is provided.

2024年1月12日 · High-content SBS polymer-modified bitumen exhibits better resistance to rutting, fatigue, cracking, and aging. Modified bitumen is a critical material to ensure the durability of asphalt pavements. Traditional polymer-modified bitumen (PMB) has been widely researched and applied in the past two to three decades.

Styrelf® PMB Bitumen is modified with elastomeric polymers using a TotalEnergies innovative cross-linking technology which gives them exceptional properties in terms of storage stability, cohesiveness, elongation capacity and resistance to aging. The Styrelf® PMB is homogenous and superior quality PMB; which enhances life of the pavement.

Modifiers and additives have been used to boost bitumen performance include: polymers, chemical modifiers, extenders, oxidants and antioxidants, hydrocarbons, and anti-stripping additives.

2016年12月25日 · The main reasons and ways of bitumen modification by polymers were examined. Positive and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic elastomers,...

2024年12月15日 · Polymer Modified Bitumen is a high-performance paving material created by blending standard bitumen with various types of polymers—most commonly elastomers or plastomers. This careful formulation enhances bitumen’s elasticity, resilience, temperature resistance, and overall stability.

2024年7月19日 · Polymer modified bitumen (PMB) is bitumen (asphalt) combined with one or more polymer materials. This modification is done with the aim of enhancing the mechanical properties of the bitumen material.

To meet modern demands, Polymer Modified Bitumen (PMB) has been developed. This study explores both wet and dry preparation methods, introducing six polymers for bitumen modification. Characterization studies reveal that polymer addition enhances bitumen properties without compromising its fundamental binder functionality.
