MATERIALS AND DESIGN OF STABILIZED SOIL ROAD MIXTURES

FIVE DESIGNS FOR MIXTURES OF MATERIALS IN PENNSYLVANIA BASED UPON COHESION, INTERNAL FRICTION AND GRADATION AS DEVELOPED BY THE RESEARCHERS OF THE BUREAU OF PUBLIC ROADS ARE PRESENTED. THESE MIXTURES RANGE FROM FINE COMBINATIONS OF SOIL WITH SAND OR SCREENINGS TO COARSER MIXTURES OF PROPERLY STABILIZED SOIL WITH GRADED COARSE AGGREGATE. PROVISION IS ALSO MADE FOR TWO COURSE WORK. IT IS RECOMMENDED THAT THE SHOULDERS BE STABILIZED WITH THE SAME MIXTURES AS THE TRAVELED WAY, AND THAT FILED CONTROL OF CONSTRUCTION BE ACCOMPLISHED THROUGH FREQUENT ANALYSIS OF SAMPLES, METHODS FOR WHICH ARE GIVEN. THE SOIL-MORTAR GRADATION IS THE HEART OF THE STABILIZED SOIL ROAD, AND IN ALL CASES SHOULD BE OF THE RIGHT COMPOSITION. COARSE GRADED MATERIALS ARE ADDED WHERE PRACTICABLE, BUT IN ALL CASES WHETHER THE BEST COARSE MATERIAL IS AVAILABLE OR NOT, THE VOIDS IN THE COARSE MATERIAL SHOULD BE FILLED WITH PROPERLY COMPOSED SOIL MORTAR. /AUTHOR/
