Just wondering if anyone has any thoughts on the rough percentage of an "undulation" is built out with succeeding layers - I had, somewhere, heard that succeeding layers build out about 1/2 of the underlying layer undulation. Had an experience where the first layer of two base courses was placed before monsoon, then traveled on for about 5 months. Scraped it off (but not scarified) and the next layer (150 mm) was placed, then chip seal. Ended up "feeling" the first base course layer undulations - not to the same degree as originally but a bit.
Your thoughts, information, would be appreciated . . .
