Heatec technical paper on polymer-modified asphalt now available for free download
Heatec has made its technical paper T-133, titled Heating, Mixing and Storing Modified Asphalt available as a free download from the company's website, www.heatec.com. Until now, the paper has been available to the public in print only. Now, visitors to Heatec's website can download it in pdf format.
T-133 covers how PMAC (Polymer-Modified Asphalt Cement) is mixed, what type of equipment is needed, and how heating and storing techniques differ from virgin asphalt cement. The paper also covers how SBS (Styrene-Butadiene-Styrene) and GTR (Ground Tire Rubber) mixing systems work.
Quotes from the paper:
"Research and testing has proved the potential value of PMAC's. It is a fact that polymers can significantly improve the performance of asphalt mixes and substantially increase the service life of highway surfaces."
"The day-to-day handling of the PMAC material will be a totally new experience for most people. The polymers and the liquid AC have a tendency to separate. So the real challenge is to keep them stored in a homogenous mixture until they can be used."
