PERFORMANCE EVALUATION OF PRE-VULCANIZED LIQUID NATURAL RUBBER (PVLNR) IN HOT MIX ASPHALTIC CONCRETE

Engineering characterisation of epoxidized natural rubber-modified hot-mix asphalt

Road distress results in high maintenance costs. However, increased understandings of asphalt behaviour and properties coupled with technological developments have allowed paving technologists to examine the benefits of introducing additives and modifiers. As a result, polymers have become extremely popular as modifiers to improve the performance of the asphalt mix. This study investigates the ...

Microbiological deterioration of vulcanized rubber.

Data are presented which show that the constitution of the recovery medium exerts an appreciable effect on the apparent thermal resistance of spores of Putrefactive Anaerobe 3679. The routine use of a simple yeast extract-starch medium (YES) as a recovery medium in thermal resistance studies on this organism is recommended. In addition to giving thermal resistance values comparable to those obt...

Investigating the Performance Characteristics of Asphaltic Concrete Containing Nano-Silica

Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

Evaluation of the Cohesiometer Test for Asphaltic Concrete

Vulcanized rubber foot for lower limb amputees.

A prosthetic workshop was started some years ago at the S.M.S. Medical College Hospital , Jaipur , t o meet the growing demands of the local populat ion. Unlike the premier limb-fitting centres in India which still cater for the more affluent sections of society, it was decided that this centre would also look after the p o o r rural amputees . I t soon became apparent that a disturbing number ...
