Globe Werneke Book Cases. Home Course Road Making VIII. —The Sand-Clay Road. By LOGAN WALLER PAGE, Director Office of Public Roads, United states Department of Agriculture. Copyright by American Press Asso ciation, 1912. A SAND-CLAY road is composed of sand and clay mixed in such proportions as to form a compact and firm support to traffic. The perfect sand-clay road should be neither sticky nor sandy. The sand and clay may form a natural mixture, In which case the road is termed a "natural sand-clay road." The two materials may have become mixed in the fields along the road by Y.y\ MIXING THE BA.XD AND CLAY. •uccessive cultivation of the soil, and ii this soil is used in the construction of a road it is known as "top soil road." There are many varieties of clay and consequently a wide variation in the characteristics of a sand-clay road. The quality of the sand is a variable factor, as it may range all the way from fine, dust-like particles to coarse grains and gravel and may be perfect ly clean or mixed with loam and other material. In consequence of these wide differences in the materials constitut ing sand-clay roads it is impossible to maintain a uniform standard as to quality of the road or methods of con struction. Not all but most sand consists of tiny grains of quartz. While quartz is one of the hardest minerals known, SHUFORD'S FURNITURE STORE it possesses practically no binding or cementing power. The grains of sand, instead of cohering in a tough mass under the impact of traffic and the ac tion of water, remain loose and shift ing. Fine sand when dry is easily displaced by the wind, which pro duces in this way the ever shifting sand hills. No road is so difficult to travel as one through fine sand. If clay has been carried in small quantities by running water and de posited as sediment it is known as "sedimentary clay." If the feldspathic rock has been disintegrated in place by water the clay is known as "residual clay." The sedimentary clay, having been carried in the form of fine par ticles, is finer grained than the residual clay and is more sticky and plastic. In contrast with sand, which possesses no binding power, but is very hard, clay is a powerful binder, but does not possess the quality of hardness. It is evident that in the construction of a sand-clay road the important property in the clay is its plasticity or tendency to become sticky and elastic when mixed with water. The clays which are most plastic are called "ball clays."-» Another important property which is possessed by clays in widely varying degrees is the porosity or ca pacity for rapid absorption of water. Clays which possess this quality in the highest degree fall to pieces under the action of water. These clays are called "slaking clays." It will read ily be seen that the plastic or ball clays will form a better and more powerful binder for sand-clay roads than will the slaking clays; but, on the other hand, they will be much more difficult to mix, as they disintegrate with far less rapidity. The shrinkage of clay is an impor tant characteristic in connection with the building of roads. When water Is mixed with clay expansion results, and when the water evaporates the clay contracts. This characteristic of ev pansion is much more pronounced in some clays than in others, and it must be apparent that the clays which ex pand the least are preferable for road building. The theory of the sand-clay road is very similar to the theory of the mac adam road. In the latter rock dust and screenings fill the voids between the angular fragments of stone and when wet serve as a cement or binder. The grains of sand may be likened to the angular fragments of stone and clay to the rock dust binder. In the most successful uand-clay road Just a sufficient amount of clay is used to fill the voids between the grains of sand. In this way the sand sustains the wear, while the clay server as a binder. If too much sand is used the result will be loose sand on the sur face; if too much clay is use.! (/„ ? face of the road will become sticky after rain* The best mixture of sand and clay can be made when the materials are wet, and particularly is this true of the plastic or ball clays. If the clay is a plastic or ball clay much greater effort will be necessary to obtain a complete mixture; if it is a slaking clay the mixture will be much more readily obtained. This kind of cls£ IS not as sfltiafaftnrv. THE HICKORY DEMOCRAT, THURSDAY, AUGUST 8, 1912 however, as'the ball clay, us its bind ing powers are much less. Ia select ing clay for road purposes it is always best to select the stickiest clay avail able. A common test is to wet the thumb and place it against a piece of clay. If the clay will not stick to the thumbi it is safe to assume that it will be a poor binder in a saud-claY/road. As the desirable proport,ions\Df sand and clay «aro such that the particles of clay baredy till the voids between the grains of sand, it is well in determin ing the quantity of clay to be applied to a saud.-road or sand to be applied to a clay road to know approximately how much is needed. "A simple method for determining the relative quantity is to take two glasses of the same size and fill one with dry sand^which it is proposed'.to use and the.other witli wa ter. The water should fjien be poured carefully* in the glass of sand and al lowed tot trickle down through the sand until it reaches the bottom of the glass. When the water'has been poured into the glass of sand to the point of over flowing*we may assume that the voids between the grains of sand have been filled, and consequently the amount of water 1 taken from the full glass would represent the volume of clay needed to fill the voids in a volume of sand equal to that in tlie other glass. It is better to use a little less clay than would ap pear to be. necessary, as the tendency is to-overestimate the amount needed. Good .drainage is the most essential feature*of the sand-clay road just as it is of all other of road. A sandy or gravelly soil affords better natural drainage, and if the sand is present to an exceptional extent the only provi sion necessary lor drainage will be to crown; the surface of the road in the same/manner as prescribed for earth, gravet or macadam roads. If the road is located through land that is so low as to be»continually wet it will be nec essary in addition to crowning the road to provide wide 'ditches on each side and to raise the roadbed a little higher than theosurrounding country. After ; proper drainage has been se cured the roadbed should bo crowned, beginning near the source *>f supply of the clay or sand. The clay should them be spread to a depth of from six to eitght inches in the center, sloping off .gradually to a thin layer at the sideK. Upon the clay should bp placed a thin covering/ of sand.

If the cla placed on sand to a depth/ of six/ inches a cubic yard *>f clay --will cover fifty-four lineal feet; consequently; a sixteen foot road treat ed in>this manner wotald require one cubic*yard.of ,clay for each three feet of length. mile of sixteen foot road ;would (therefore* require 1,7d0 cubic;yards of clfty. If the clay'subsoil istto be treated with sand it should be flowed and harrowed to n depth of about four inches. On this prepared subsurface should "be "placed from six to eight inches of clean .sand, spread thickest at the anct sloping to the sides "TH TiTmil uu . i- manner as me clay is «ppli"l to a sand rufltl These ma (crisis h"iiUl then be mixed dry in stead of the wet mixing, which is preferable when clay is applied to sand. This is preferable because the clay can be better pulverized when in a dry state. After dry mixing the road should be puddled following the first heavy rain.

As It is impossible to determine exactly the proportions of sand and clay to be used in the first place, it is necessary to give careful attention to the sand clay road for a considerable time after it is completed. In order that addition al sand or clay may be applied as needed. In 11KH there were only 2,900 miles of sand-clay roads in the United States, but at. the present time there are ap j proximately 25,000 miles. More Favorable Ground.
