) THE SUNDAY STAR, WASHINGTON, D MINISTER'S CHURCH ON WHEELS | foth wistecoiatie vy TO "BLACK BASE" AS STANDARD Asphaltic Concrete of Broken Stone and Cement Being Adopted as More Economic and Lasting Type. Highway engineers who are striv- hng constantly to perfect more eco- nomical and lasting types of pave- jment are reverting to a type laid n the eastern states as far back as rorty years ago, but which has found more comprehensive development lahd has entered into more general se in the Pacific coast states—a type Ipopularly known as the “black base™ nd composed of au asphaltic con- crete made with broken stone and usphalt cement and laid at a thick- hiess of from two and one-half to ftour inches. This type of construction s adopted as th hhlacements of foundation cuts on 3 avenue by _Clifford Pinckae: hief engineer of Manhattan borouxh. w York city. very twenty-four Lours 350,000 vehicles pass over the kiieet asphalt pavement on 5th venue, the finest paved thorough- are in the world. The pavement on is avenue is cut-open on an aver- %e of every forty hours for the re- alr or extension of the city's many inderground lines of communication yr service. The base under the treat ‘asphalt surface of 5th avenud s first constructed was of Portland -ement concrete. Hereafter, however, very opening in the pavement will he restored with the ‘“black base. his type of base has been selected because trafic is interrupted only during its actual construction, while he former type of base necessitated ‘losing the repaired section to trafc qr as long as seven days in order o give it time to set or harden. Other ualities of the “black base,” accord- ng to engineers, are its firmness and silient mature, its ablility to expand and contract without cracking. its aterproof nature and its resistance o the heaviest traffic impact. Be- ause of its flexibility. they say, | naintains contact with the under- Pying sofl and therefore retains its upporting value at the maximum. hese qualities, it Is held, give it a lecided advantage over a rigid base nd do mot necessitate its construc- ion in heavy thicknesses or its rein- orcement with steel. It possesses n advantage, according to engineers. ver a rigid base also because it erges with the surface of the high- wvay and forms a homogeneous slab, hile the hard, rigid base forms no ond with the surface and emphasizes rface tendencies to wave or crawl ‘he “black base,” engineers say, daptable to any type of surface, in- recentl luding granite block, wooden block|? nd brick. More than 11,000,000 square yards— to be exact, 11,283,349 square rds—of asphaltic concrete bas pavement, averaging five inches in hickness, are now in use on the Pa- ific coast, particularly in California, regon, Washington, Arizona and evada. Long service at low cost, ccording to engineers, explains the apid advance in the adoption of this ¥De of construction In the west. Contracts in Oregon. The Oregon state highway commis- ion awarded contracts recently for 7.3 miles of highway, with a three- hnch asphaltic concrete base and a wo-ineh asphaltic concrete wearing urface.

The extent to which American cities and other municipalities are now doing their own street repair work with the ald of their own as- phalt plants is indicated in reports to the Asphalt Association, New York city, which show that there are in the United States ninety-six publlc asphalt plants. Municipal plants are to be found in_ the following citles Little Rock, Ark.; Los Angeles, Cal. Denver, : Del. Topeka, Kans.; Shreveport, La. ‘Worcester. Mass.; Lansing.

L ATTERY STORY PRINTED [PENNSYLVANIA TO BUILD LAST SUNDAY INCORRECT Float Will Ride High When Bat- # tery Is Low” Wrong, Con- verse Being True. The battery story which appeared in ast Sunday’s Star entitled “Float Will Ride High When Battery Is Low,” was ncorrect. The story should read as ollows: “How can that little glass ‘do- itter’ tell whether a battery is fully ged or mnot?” dublously queries me falr lady motorist during the hay’s work at the average battery erviee station. And many a man ould like to know more about the ame subject, but he does not like to onfess his ignorance—his curiosity is ot quite so keen. The explanation is simple, indeed. nd very reasonable when one give: t sufficient consideration. It hap. ens that the sulphuric acid used in a battery solution is heavier than water lone, and the hydrometer used for ttery testing merely indicates the elative welght of the solution com- pared with the weight of pure water. ‘When a battery is discharged a great meunt of the acid in the battery. utifon has combined with the lead ompounds in the plates. Naturally he solution is weak in acld and the oat rides deep. But when the bat- ery is charged and the acid is in the olutlon—the solution has become ieavier—and the hydrometer float jdes high. The Willard Storage Battery Com- any and many other manufacturers fecommend the regular and frequent esting of batteries with the hydrome- er. Unless a battery has been med- lied with by some inexperienced per- on, this malkes a reliable test of the | Lincoln tate of charge. NEW CONCRETE HIGHWAYS Bids Opened for Construction of About Sixty Miles of Road Through State. The Pennsylvania state highway department has opened bids for the construction af about sixty miles of new concrete highways. On the twenty-seven projects 220 contractors submitted bids. On one four-mile project seventeen bids were received. Another drew sixteen bidders and a third fourteen bidders. The total low bid approximated $3,00,000, or $53,- 333 a mile. Low bids submitted for 31.7 miles of eighteen-foot reinforced conorete pavement totaled $1,735,314, or $54.000 a mile. While on 21.7 miles of sixteen-foot reinforced corjcrete road, the bids averaged $45,000 per mile. The total highway mileage for Pennsylvania, as given in a recent ification presented to a Congres- 01 . Mac- chief of the Unitea States bureau’ of public roads, is 91,556 miles, of which 3,300 miles, or 3.6 per cent, constitutes the state highway system. The state highway department has available from different sources $80,000,000 for the state system. At the rate of §54,000 a mile, should the department _extend _its policy of building _ eighteen-foot reinforced concrete to the entire mileage, it is estimated that the state highway ystem would cost $178,200,000. At the rate of $45,000 a mile for sixteen- foot reinforced concrete the. -3,300 miles would cost $148,5600,000. The tendency is growing among highway engineers to reinforce con- crete rosdways with more and more steel or iron. The highest types of reinforced _concrete roadway _pro- posed for the “ideal section” of the highway will cost about $100,000 a mile.

A few days ago there rolled into New York & light motor truck equipped with every comfort and convenience for camping. In #t were Mr. and Mrs. Charles Uhlyk of Los Angeles, Calif., Who were just completing a pleasure Jaunt that began at the California city on June 6. A third member of the party and one that secemed to get as much fun out of the journey as any- one else was a doc.

They were never in a hurry and simply saun- tered along looking for recreation and sport. Truek Named Wanderlust. After passing St. Louis the little truck, with the name ‘‘Wanderlust” neatly painted on each side, went north and spent several weeks touring the shores of the lakes. When Albany was reached a side trip was made through New England. When the car reachcd New York two of the United States tires contained the same air with which they left California. One of the others had to be repaired because of a puncture, and the second sustained & stone brulse. Mr. and Mrs. Uhlyk will remain in New York until March, when they will again board the Wanderlust and start for home. They will go home by the southern route, going first to Miami, Fla., and then on to New Or- leans and across Texas to El Paso. No Dull Moments. “As a means of education I know nothing that compares with such a trip.” sald Mr. Uhlyk. “We have seen | most of the natural wonders of our country, hl_lVe visited most of its im- portant citits and have traveled thou sands of miles along dreary places. But even the desola came to have an interest after a X There wasn't a dull moment in the trip. We jogged along, just having a good time, and finihed the trip two, weeks sooner than we expected. Buses Busy in Britain. Motor buses are being operated by highly organized methods, reports London dispatch to the Boston news bureau. There are 5000 omnibuses in regular operation in England, rying twenty-five to thirty persons with an average speed of twenty miles per hour. They make fourteen- day trips through Wales at charge of $112. They are now taking sengers from London to the Highlands, a seventeen-day trip, with ;l;;obesv. hotel service, for a fare of 600 Transport Companies.
