Dynamic mechanical behavior of polymer modified bitumen
Materials Research Innovations, 2002The dynamic mechanical behaviour of bitumen (BIT) modified with styrene/butadiene/styrene block copolymer (SBS)were investigated. Dynamic mechanical analysis (DMA) were performed in the temperature range -80 to 60 oC. The primary viscoelastic functions were determined at the traffic frequency, 5 Hz.

Waste polyvinyl chloride‐modified bitumen
Journal of Applied Polymer Science, 2006AbstractPolyvinyl chloride (PVC) pipe wastes have been employed as a soft filler up to a level of 11 wt % in making bituminous products for paving applications. The PVC wastes were homogenously mixed with bitumen in the molten state. The viscoelastic properties of the bitumen blends such as storage modulus, loss modulus, and dynamic viscosity were ...

Bitumen modified with reactive polymers
2012The aim of this paper was to study the effect of the addition of two types of reactive terpolymers on the bitumen rheology. Eight polymer-modified bitumens (PMBs) were produced by mixing two types of bitumens with two types of reactive polymers, ethylene – butylacrylate – glycidylmethacrylate Elvaloy AM and Elvaloy 4170 terpolymers, using polymer ...

Natural weathering of styrene–butadiene modified bitumen
2011This chapter reports on the long-term weathering of 12 bituminous sealants that contain thermoplastic elastomers, namely block copolymers of polystyrene and polybutadiene. The goal of the work was to determine the rate and mechanisms of sealant weathering so that future accelerated aging tests could be developed.

Environmental Science and Pollution Research
Conventional bitumen is a viscoelastic material composed of asphaltene and maltene. It is prepared by air-blowing, but this approach makes the bitumen more brittle and susceptible to temperatures. To decrease the temperature susceptibility, synthetic polymers or additives are used to make polymer-modified bitumens.

Production of recycled plastic modified bitumen- Effect of base bitumen
In this study, two different viscosity grade base bitumen (VG10 and VG30) and 3 dosages (2%, 3%, and 4%) of recycled low-density polyethylene (RLDPE) were selected for the preparation of the recycled plastic modified bitumen (RPMB). All modified bitumen were evaluated for physical, morphological, and rheological properties.Deb, S., Kumar, P., Saboo, N.

CREEP&RECOVERY-POLYMER MODIFIED BITUMEN
2013Rutting, defined as accumulated permanent deformation, is a common form of distress in asphalt pavements. Rutting failure leads to poor serviceability of the pavements, making vehicles ride rough and unsafe. The increasing demands of traffic on road building materials in recent years has led to the evaluation, development and use of a wide range of ...
