It would be a fraction of the life expectancy of concrete however prob 1/2 the price too as well as not so slippery in the frosty moments. There has been a fair bit of deflection as the main problem is the base coarse under the seal is bad & turns to mud during heavy rains (which we seem to get once a year). The water runs into a pothole at the top of the drive & sluices out huge amounts of foundation out of a lower hole 20-30m further down the driveway.
Our existing one has been there since about 1984 & has many big holes in it. I have patched them up over the 14years i've been here but there comes a time when things have to be done right.
Judging by the way a couple of companies haven't returned any calls for competitive quotes i would say they have their hands full at the mo.
