I'm searching for best blend of waste polyethylene between (high density, medium density and low density polyethylene) for improving mechanical properties of hot mix asphalt against rutting, fatigue and low temperature cracks. so ineed the best percentage of each polyethylene that should be used and the methodolgy of mix (wet or dry)? thanks.
The use of LDPE (Low-Density Polyethylene) and MDPE (Medium-Density Polyethylene) as asphalt modifiers can enhance mechanical properties. Achieving the best blend involves experimentation, but a general approach is to combine different percentages of LDPE and MDPE to optimize performance.
Always consult relevant guidelines, and consider working with a material engineer or specialist in asphalt modification to fine-tune your mix based on specific project requirements and local conditions.

I suggest that you visit the AUSTROADS website and look for the publications prepared by RMIT where they investigated various types of plastics for use in asphalt. Thee are available for free download.

Utilizing LDPE (low-density polyethylene) and MDPE (medium-density polyethylene) as asphalt modifiers can enhance mechanical properties. However, determining the optimal blend and methodology requires careful experimentation and consideration. Here's a general approach:
Remember that the ideal blend and methodology may vary depending on factors like asphalt composition, climate, and traffic conditions. Collaborating with experts in asphalt engineering and conducting thorough testing will help refine the optimal blend and application method for your specific requirements.
