Crumb rubber modified bitumen (CRMB) can be regarded as a binary composite system in which swollen particles are embedded the matrix. Previous study has successfully implemented micromechanics models predicting complex moduli of CRMB binders using more representative constituent parameters. In regime master curves, while used predicted well high-frequency range, they underestimated modulus low-...

This study investigated the effects of swelling-degradation degree on rheological properties and thermal pyrolysis behaviors crumb rubber modified bitumen (CRMB). The equilibrium viscosity CRMB in 160 °C-swelling process is 10.5 Pa·s at 8 h. During 200℃-degradation procedure, increased to a maximum value 20.58 7.5 h gradually reduced stable 11.09 after 35 swelling degradation processes exhibit ...

Layered double hydroxides (LDHs) are an ultravioletlight (UV)-resistant material. In this study, two types of LDHs (Mg-Al-LDHs and Zn-Al-LDHs) were applied to modify bitumen by melt-blending. The effect of ultraviolet aging on the rheology and chemistry of LDH-modified bitumen was studied by means of dynamic shear rheometer (DSR), thin-layer chromatography with flame ionization detection (TLC-F...

The population of our country is increasing rapidly and due to it plastic waste is also increasing day to day due to urbanization, development activities and changes in life style, which leading extensive environment pollution. Thus disposal of waste plastic is a threat and become a serious problem globally due to their nonbiodegradability and anaesthetic view. Since these are not disposed scie...

Plastic (Polyethylene Terephthalate, PET) is now used as packaging material for a whole range of consumer products in addition to carbonated beverages. Although plastics are very useful product, but the disposal of these wastes has become a problem and is of great concern, particularly in our country. One of the solutions to the disposal of plastic wastes is recycling it...

SMA is a gap graded mix composed of high concentration coarse aggregate that held together in thick asphalt film by matrix mineral filler and stabilizers. Since natural aggregates have become expensive, hence Reclaimed Asphalt Pavement (RAP) can be reused pavement construction to reduce the environmental hazardous due disposal problems. RAP contains used aggregates, it highly prone fatigue, the...
