Show GOOD ROADS NOTES Slipping- on hilly roads is one of the unfortunate results which horses must suffer as a result of covering the roads with hard surfaces, while the possibility of skidd I nt; on these slopes Is an ever-present ever-present dread anion? motorists. A special form of paving: bricks, called "hillside bricks," Is made for use on grades exceeding ex-ceeding one foot rise in twenty feet horizontal hori-zontal distance. These bricks have grooves cut across their tops to hold the shoes of the horses and the tires of the cars, and have ben received with much favor by road builders. Recently the same object ob-ject lias been attained with bituminous roads built on hills by leaving them with a rough surface. This met hod of construction con-struction was developed by the Massachusetts Massa-chusetts state highway commission. According Ac-cording to Kngineerlng- News, the roadbed is covered with broken stone from two to three Inches In size, which "Is rolled until the bed is three inchos thick. This bed then has hot asphalt applied to It by a pressure dist ributnr at the i ate of two and three-quarters to three gallons per square yard. This asphalt fills the spaces between the stones, but the latter are so large that their tops project somewhat above the asphalt binder and thus afford a foothold. As a natural result of its popularity with the motor-traveling public, the Lincoln Lin-coln highway seems dest ined to carry a tremendous volume of traffic In 1 f 1 7 . The Increase of through travel on the highway in the past two years lias been more than 600 per oent. A few years ago about 100 miles of roads were improved in Spot sly van la county, Virginia, which is far from being be-ing a wealthy county. This resulted in much heavier loads, particularly loads of lumber, on narrow -tired wagons, and these ffreat weights on a few inches of tire began to injure tho roads conslder-nhlv. conslder-nhlv. So the countv supervisors passed an ordinance limiting loads to 4000 pounds on wide-tired vehicles and 2i00 pounds on those with narrow tires. Many teamsters team-sters hauled more than the ordinance permits, per-mits, and ft was necessary to indict a number of them before they realized that tho supervisors proposed to have the law obeved. Most of the teamsters have now provided themselves with 3-lrich tires for two-horse vehicles and 4 to rt-lnch tires for four-horse vehicles. This saves the road. The teamsters have found that they do not suffer, for on account of the easy hauling due to a good road tlmy often hitch one wagon behind another and haul both with four horses, thus doubling tho work done by the team and driver. Easterners returning from the Pacific coast over the Lincoln highway during the latter part of lfUS voiced their milled praise of the excellent road marking, the work having been done bv the Lincoln Ulghwav association. A well-marked rond Is a great Influence in drawing tourists and for this reason the Lincoln highway-Is highway-Is expected to draw additional throngs of niutorlsts during the coming year. The relocation of old roads seems to be something mysterious or un annvr to so run n v f n xpa vers t bat tl fi fviiiiHyU nnin highway department has had an unusual model made to show just how such work betters traveling conditions. This model measures six by five J'ect and was made by a specialist in such work at Washing- 1 ton. It is in relief, with roads, fields. ; houses, trees and other fca lures of the landscape reproduced to a correct scale. On it are shown throe types of poorly located lo-cated roads frequently found and the proper method of relocating each so as lo provide satisfactory grades and connect the terminal points in the most direct manner. The model also shows three types of road construction, waterbound macada m, bituminous concrete and cement ce-ment concrete, with bridges and culverts of standard types. This model is bcinp' shown at county fairs and has attracted unusual attention, so it may be considered consid-ered a decidedly successful educational exhihit which other state highway departments depart-ments may find tt desirable to duplicate. I Officers, directors and ot hers Interested Interest-ed in the improvement of tho road from Detroit to Chicago recently gathered In Ivala.mazoo, Mich., at the annual meeting meet-ing of the Michigan Paved Way aNsncia,-tion. aNsncia,-tion. It is expected that tin; road will be materially- "bettered during the coming com-ing year. iRoad building In very dry climates Is bese' with troubles the reverse of those In most parts of the country. The average aver-age road builder Is continually striving to Improve the drainage of his roads, and to keep water away from them, whereas In a dry climate the endeavor is to keep them damp. The earth and gravel roads of tho country are best main tained by dragging them after c ery i a in. but in a country where there Is very little rain a well-dragged road is a luxury, in the imperial valley of California, for Instance, water obtained primarily for Irrigation is used to wet highways before drai;ilu;; them. Water iias also been diverted from Irrigation to road building In Arizona and New Mexico. Tn Utah, alter attempting without success to keep gravel roads in good condition by sprinkling them with wiiWoring carts, an experiment is now being be-ing made with more drastic methods, tho roads being drenched instead of sprinkled. sprin-kled. In most cases, however, oil is used rather than water, but unions It Is of an unusually good quality for the purpose t lie results are not good. The dust from a road sprinkled with an unsuitable oil. in the very dry regions is sometimes almost al-most suffocating, and inoro uhjectiunahle than that from an unoiled road. |
