TIOGA PRESS. CEMENT-TREATED BASE SUCCESSFUL AT 10,000 FEET ELEVATION

AN ACCOUNT IS GIVEN OF THE RECONSTRUCTION OF 2-1/2 MILES OF GRADED EARTH ROAD AFTER THE FAILURE OF A LIGHT BITUMINOUS SURFACING. THE ROAD, WHICH CROSSES THE SIERRA NEVADA WAS AFFECTED BY SPRINGS, SEEPAGE, AND THE FREEZING AND THAWING OF SNOW. THE ROADBED WAS SCARIFIED, AND THE BASE STABILIZED BY THE ADDITION OF COARSE MATERIAL AND CEMENT, MIXING BEING AFFECTED BY A TRAVELING MIXER. AFTER GRADING AND ROLLING, BITUMEN EMULSION WAS APPLIED AND THE ROAD WAS SANDED. A 3- INCH SURFACING OF BITUMINOUS ROAD-MIX MATERIAL WAS LAID IN TWO COURSES AFTER THE WINTER, NEARLY A YEAR LATER. SINCE THEN, THE ROAD HAS SUFFERED VERY LITTLE DAMAGE FROM WINTER CONDITIONS OR FROM SNOW-MOVING EQUIPMENT.
