SUB-BASE TESTS ON ROUTE 26, WASHINGTON COUNTY, OHIO

POROUS SUBBASE TESTS SHOW 1.29 FEET OF CRACK FOR EACH LINEAL FOOT OF CONCRETE ROAD ON THE NATURAL SOIL AND FROM 0.45 TO 0.47 FOOT ON VARIOUS POROUS SUBBASES AFTER TWO YEARS OF SERVICE. SURVEYS OF THE CRACKING CONDITION LEAD TO THE FOLLOWING CONCLUSIONS: (1) THE CEMENT-CLAY ADMIXTURE APPEARED DURING CONSTRUCTION, AND SHOWS IN RESULTS SINCE TO BE LITTLE IF ANY DIFFERENT THAN THE NATURAL SOIL BASE, (2) THE POROUS BASES SHOW MUCH LESS CRACKING THAN DO THE NATURAL SOIL AND ADMIXTURE OF CEMENT AND SOIL BASES, (3) THE INCREASE IN CRACKS DURING THE SECOND YEAR SHOW SIMILARLY FAVORABLE RESULTS FOR THE POROUS BASES, AND (4) IT IS UNSAFE TO DRAW CONCLUSIONS UPON THE SUFFICIENCY OF TWO, FOUR, OR SIX INCH POROUS BASES TO SAVE THE ROAD MAINTENANCE AND EQUIVALENT OF THEIR ORIGINAL COST.
