Monitoring separation tendency of partial asphalt replacement by crumb rubber modifier and guayule resin

Construction and Building Materials, 2020
Abstract Guayule resin was utilized as a partial asphalt replacer for sustainable, flexible pavement. This research aimed to study the effect of such an innovative replacer on asphalt-rubber separation tendency. The replacement denoted 25–75% triggering a binder competitive with conventional asphalt.

Degradative Effects of Guayule Resin on Natural Rubber

Rubber Chemistry and Technology, 1981
Abstract This study indicates that the degradative effects of guayule resin on natural rubber are due to the presence of unsaturated fatty acids in the resin. Since linoleic acid is, by far, the most abundant unsaturated fatty acid in guayule resin, it appears that linoleic acid is primarily responsible for the degradative effects of guayule ...

The leachability of guayule resin from treated wood

Industrial Crops and Products, 1993
Abstract Field evaluation has shown that guayule resin has potential as a protectant for wood against damage by terrestrial wood-destroying organisms. When used in this capacity, it is essential to know whether the resin migrates from the wood, as a contaminant, into the natural environment.

Degradative Effects of Guayule Resin on Natural Rubber. II. Kinetic Studies

Rubber Chemistry and Technology, 1982
Abstract Qualitative studies reported earlier and the kinetic studies reported here indicate that the unsaturated fatty acids in guayule resin are primarily responsible for the ability of guayule resin to accelerate the oxidative degradation of natural rubber.

Conversion of guayule resin to C1-C10 hydrocarbons on zeolite based catalysts

Fuel, 1992
Abstract The conversion of guayule resin to C 1 -C 10 hydrocarbons, using different zeolite based catalysts, has been studied. HY, CaHX and HZSM-5 zeolites and a silica-alumina amorphous matrix were tested. The best results were obtained with a physical mixture of 70 wt% HZSM-5 zeolite ( Si Al = 13 ) and 30 wt% silica-alumina amorphous ...

Smoke and toxic species analyses from controlled combustion of wood impregnated with guayule resin

Polymer-Plastics Technology and Engineering, 1996
Abstract Dominant commercial treatments currently used for wood preservation are pentachlorophenols (PCPs), creosote, and chromium copper arsenicals (CCAs). These wood preservatives present many studied and documented environmental and toxicological problems both with use of the products themselves and with the production of secondary reaction ...
