ABSTRACT:
The employing of finely-divided and naturally-occurring particulate matter of Trinidad Asphalt to lock or hold the aggregate filler mixture of the pavement mix in position, almost entirely filling the mix with soft bitumen, permitting subsequent compacting (as by rolling) to a state of substantial voidlessness, and thereby achieving a pavement which is both strong with respect to bearing strength yet soft and/or flexible with respect to its tendency to crack, and which will optimize a sort of self-rehealing of the membrane if cracking should start to occur.
