Show EXPERIENCE After years of experience, the best and most progressive progress-ive road builders of today are admitting that they are up against a problem which they are unable to solve. How to build a road for the money they have in sight which will hold up the big motor traffic of tomorrow. Roads which ten years ayo were considered to be permanent per-manent improvements and paid for out of forty or fifty year bonds, are rapidly going to pieces, before the first payment' on the bond principle is due. Concrete roads, macadam roads, block roads all are going. In 1912 there were but 60,000 motor trucks, mostly one and one-half tons and smaller. Today there are 700,000 and lots of them six to e'ight tons. A few years ago the government offered a prize for an armour plate that no projectile could penetrate, and at the same time it offered a prize for a gun which could throw a projectile with such force that it would penetrate any armour plate made. The same strife is on now between the road builder and the auto truck builder. The better the road builder does h'is work, the heavier and more powerful the truck is built. n |
