Polymer Modified Bitumen. Polymer Modified Bitumen ( PMB ) is one of the bitumen grades products which specially engineered and designed that are used in making roads and pavement for heavy duty traffic and Polymer modified bitumen also are used in home roofing solutions to sustain extreme weather conditions.
modified bitumen in a warmer zone or in a zone with heavier traffic. According to Table (5), given the fact that the maximum amount of SBS providing ductility equals 100 cm is a composite with SBS of 4 weight percent of bitumen. Table 5. The results of performed experiments on base bitumen and SBS polymer‐modified bitumen samples
Polymer modified asphalt plant includes: two reactors, colloid mill, an oil heater (used to heat the bitumen without damages), bitumen supply pump, polymer feed pump, bitumen valves, control cabinet, technological heating system, an input node of adhesive additive, plasticizer, and polymer loading platform.
V. Mouillet, ... E. Chailleux, in Polymer Modified Bitumen, 201112.3.1 Analysis of PmB by infrared microscopy The formation of a functional modified bitumen system is based on the dissolution and/or fine dispersion of polymer in bitumen and on the compatibility of the polymer-bitumen system. ...
Application of Rheology in Bitumen and its modification Descripción: As per the recent BIS norms, the application of Rheology into Bitumen and Polymer Modified Bitumen (PMB) binder testing will also require Dynamic Shear Rheometer (DSR) measurements. The ...
Polymer modified Bitumen Production of hot asphalt mixes with Polymer modified Bitumen (PMB) is mandatory for enhancing the performance of bitumen used in road, runway and racetrack applications both by improving life expectancy and reducing maintenance levels.

The optimised mechanical properties of the resulting asphalt mixtures ensure improved durability at full exploitation of the road surface (depends on the thickness of the applied layers). The use of polymer-modified bitumen also enables the optimisation of maintenance procedures and increases road traffic safety in the event of 'porous' layers.

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 fatigue, stripping and deformations, making it a favorable material for infrastructure.
The type of substrate and the performance objectives influence the specification of the modified bitumen membrane system. Asphalt used in manufacturing modified bitumen systems is generally modified with one of two modifiers: Atactic Polypropylene (APP) or Styrene Butadiene Styrene (SBS).
Polymer Modified Asphalt Cement (PMA) is an improved version of Asphalt Cement produced by adding either natural polymer (such as para rubber) or synthetic polymer (such as SBS or EVA) together with an additive. PMA will provide better strength and durability of road surface than Hot Mix Asphalt (HMA), due to: High resistance to wear
One of the most beneficial aspects of polymer modification is the reduction in the modified asphalt’s low temperature stiffness. Extensive laboratory testing has shown that ULTRAPAVE ® SBR Latex Polymers can reduce the low temperature stiffness greatly reducing the chances of thermal cracking.
These parameters impact the mechanical properties of the polymer, and therefore the properties it will bring to polymer-modified bitumen. Now let's focus of the main properties brought by the polymer-modification of bitumen: Polymer modification stiffens of bitumen at elevated service temperatures, say around 50 to 70°C.
Modified asphalts are often generically called “polymer modified asphalts.” Polymers are probably the most common type of modification, but today’s modified asphalts may be produced in several ways.

standard paving grade bitumen need to be updated or modified in order to cope with the requirements from the polymer modified binder. The present report is a contribution to the ERANET Road project “Possibilities for high quality RECYling of Polymer Modified Asphalt” which bears the project acronym RECYPMA.
PMM – Polymer Modified MasterSeal – Asphalt and Blacktop Sealcoating. Polymer Modified MasterSeal (PMM) is a high performance mineral reinforced asphalt emulsion sealcoat blended with polymers and special surfactants for superior adhesion, flexibility, and durability.
The rheological behaviour and viscoelastic properties of bitumen and polymer-modified bitumen are very important both from a practical application perspective but also in understanding fundamentally the effect of polymer addition on mechanical properties, bitumen morphology and polymer–bitumen interactions.
