Time dependent viscoelastic rheological response of pure, modified and synthetic bituminous binders
Bitumen is a viscoelastic material that exhibits both elastic and viscous components of response and displays both a temperature and time dependent relationship between applied stresses and resultant strains. ...

Accelerated swell testing of artificial sulfate bearing lime stabilised cohesive soils
This paper reports on the physico-chemical response of two lime stabilised sulfate bearing artificial soils subject to the European accelerated volumetric swell test (EN13286-49). At various intervals during t...

Open AccessDiscrete element modelling of uniaxial constant strain rate tests on asphalt mixtures
Constant strain rate tests for a graded asphalt mixture under three constant strain rates have been undertaken in the laboratory. The Discrete Element Model has been used to simulate the laboratory tests with ...

Styrene butadiene styrene polymer modification of road bitumens
This paper describes the polymer modification of road bitumens with SBS. Six polymer modified bitumens (PMBs) were produced by mixing bitumen from two crude oil sources with an SBS copolymer at three polymer c...

Viscoelastic linearity limits for bituminous materials
As bituminous materials are viscoelastic in nature, their performance must be characterised using test methods and analytical techniques that account for time (or rate) of loading and temperature. In addition,...
