The thrée most nutable examples of the test road, which is just what the varying mater’als and then to name implies—a road built of “tested destruction” in a comparatively short time by running abnormally heavy traffic over it—are the Bates Test Road in Ulinols, the Pittsburgh, California, Test Road and the High. ‘way Exper!ment Station at Arling- ton, Virginia, conducted by the SKIDDING AND HOW TO PREVENT IT A good driver rarely allows his car to sk d, for skidding is mostly caus ed ally start by poor driving, because you Skids gener- do one of two things you should not do on a slippery har: ly c to start a rear wheel skid!

Of the various test roads referred tous manner. A number of trucks given to the Illinois Highway De- partment by the United States Army as part of surplus material first made 1000 trips over the road with a lead of 2,500 pounds on each rear wheel and 2250 pounds on each front wheel This was followed by four other test runs in which the load on the rear wheel was gradually in- ereasod “to 6,500 pounds and when th's hed been finished, a sixth and final run was mage at night when the trucks made 5,000 trips with an 5,000 pound wheel load. This was done because of the fact that at night the strength of the surface differs in some ways from its strength during the day. For ex- ample, on a concrete highway the edges of the pavement curl up slight- ly from the subgrade due to the cool- er air. These pavement-destroying runs wre made with the whee's of the trucks to make every possible the most conspicuous example. It is a little more than two miles long, 18 feet wide and consists of 63 sections, most of them 100 or 200 feet long surfaced with various types of pave- ment. Brick, asphaltic concrete, cement concrete and other frequent- ly used types make up the road. This road was subjected to the most thoroughgoing, back-breaking _ or- deal that any highway ever went through. In a space of three or | four months as much as 377,460 tons of traffic passed over the stronger sections of this road. Some of the weaker sections got off more easily, but only because they broke up be- fore the limit was reached, Of the orginal 63 sections only 9 survived without breaking and 4 showed fail- ures that were probably due to ex- plainable causes other than heavy traffic. the experiment on the The test was made tn Road wat Rates Test the Ilnois High very Ingen- ‘airection to that in Which you were going. | An expert driver can perform the feat of skidding his car completely around, and can do it very easily, but it’s not a trick the ‘writer would advise the average driver to try. The beSt way to prevent front wheel skids is to fit non-sk’d tires to front and rear wheels. With good non-sk‘ds fitted you will have little to fear from front wheel skids, A rear wheel skid is a much more common occurence than a front wheel skid, but fortunately is much easier to correct. When your car starts a rear wheel skid. take your foot off the brakes at once, and also take your foot off the acce'erator (but do not close the throttle completely, as this would have the same effect as aplying the brake.

The Pittsburg Test Road in Call- fornia, consisted of an elliptical track built, like the Bates Test Road, of various kinds of surfacing. It was at first subjected to the pound ing of thirty full loaded 3% and »- ton trucks and at the end of that time four of the thirteen sections faled. Later on, numerous other tests were made on the Pittsburgh road, including a 16-ton load and at the end a 50-ton load on two wheels. This last load was obtained by con- structing a special trailer which was fited with pig tron and imposed a load of 5.000 pound per inch width Needless to say, this terr'- of the road to powder. survived, ho One section at the same time giving the brake pedal gentle jabs. Rear whee! skids are usually caus- ed on a slippery road by the steady application of the brakes, and es- pec'ally brakes that are not ndjust- ed property. If your car is suscep- tible to skidding, I would adv'se you test the brake adjastment to see that both wheels stop together when the brake is applied. If one wheel stops before the other, the car will skid very easily and be hard to contro} on a slippery road. To test the brake adjustments jack up both rear wheels and securety chock up the front wheels. Now get into the driving seat, start the engine, push out the clutch and en gage hich speed gear, then let the clutch in and speed up the engine to about the same speed {t would be re volving on the road at about 15 miles an hour. Now have someone watch the rear wheels wh'le you push out the clutch and apply the brake.

Don't try.to correct this kind of a skid by turning the steering wheel still fur- ther round, or you may suddenly find yourself the next few seconds with a car that has turned complete- ly around and is facing the opposite CASPER MOTOR BUS LINE CY Casper NORTH CASPER Rush Hour 207% North from | Leaves End of Kieond oof uy GMS to 7 P.M) 222% 00 11 and all evening 237% 5 226 Saters 30 241 245 256 : GRANT STREET 386 South Ash Street ~ : EAST SECOND pe SR et a a A Leaves Rialto | Leaves End of | Kenwood Bus CY Bus [| No. Casper zs : " :18 a 18 a 230 221 374 0 ’ 242 251 | 37% :42 :39 3 25214 254 :53 Arrive End of Leaves Rialto cane 15 wed Leaves Rialto Leaves End of Line ie i 45 “a4 200 710 nee :20 :30 First Bus 6:30 A.
