Show WIND HELPS ROAD BUILDERS t When Used in Construction of High ways in New Mexico Experiment Is Successful. A new method of using the wind In sand-road construction has proved so successful, that, after making a nine-mile nine-mile experimental stretch in New Mexico, Mex-ico, roadmakers in that state have built 80 miles of similar highways. First of all, the grass and weeds are cleared from the right of way, and then a trench is made through the sand to the clay bottom. The loose sand is deposited in stacks ten feet from either side of the cut, and the rest of the work is left to the desert winds. During the spring and fall, the winds sweep away all the sand and widen the clay strip. Then the road is graded and the work finished. |
