Please explain in engineering terms how IntegraBase improves the road structure – stress, strain, etc. Please note if there are different explanations for use in binder or base course applications?
The two main reasons: changing the molecular weight of the asphalt, giving it the strength that it has. The aromatic platelets get crosslinked, linking the platelets vertically as well as the traditional horizontal link. This crosslinking eliminates the typical flow of asphalt. Base/binder course doesn’t make a difference. When a load is put on a beam (the beam flexes), the top molecules push together, and the bottom molecules pull apart. This puts the top in compression and the bottom is in tension. This is the difference between cracking. If the binder is in compression, it can’t crack. IntegraBase keeps the base/binder course in constant compression (or constant stress). It is important to try to put the tension deeper into the road into the basecourse, or better yet, into the subbase, then you can eliminate cracking.
