STUDIES ARE REPORTED ON THE SKID RESISTANCE OF LINSEED OIL-COATED CONCRETE PAVEMENTS. LINSEED OIL COMPOUNDS CAN BE APPLIED TO NEW, OLD AND PREVIOUSLY OILED CONCRETE, AND A RAPID RECOVERY TO ORIGINAL SKID-RESISTANCE VALUES CAN BE ACHIEVED. IN A NUMBER OF TESTS, DRY SKID-RESISTANCE VALUES WERE RESTORED WITHIN 3 HOURS. AT A LOW TEMPERATURE OF 40 F, RECOVERY IS DELAYED TO BETWEEN 3 AND 19 HOURS. WET SKID- RESISTANCE VALUES ON TEST BRIDGES USUALLY RECOVERED TO ORIGINAL VALUES WITHIN 3 TO 24 HOURS. LONGER RECOVERY TIMES WERE ENCOUNTERED WITH WET SKID RESISTANCES UNDER CERTAIN CONDITIONS SUCH AS LOW TEMPERATURES AND NO TRAFFIC. PRECAUTIONARY MEASURES TO REDUCE HAZARDS FROM THE APPLICATION OF TOO MUCH OIL ARE DISCUSSED. FACTORS WHICH NEED TO BE CONSIDERED BEFORE OILING ARE: THE AMOUNT OF OIL TO BE APPLIED, EXTENT AND NATURE OF AREA TO BE COATED, TEMPERATURE OF THE ROAD, THE EVENT OF RAIN, AND THE AGE, FINISH AND PREVIOUS COATINGS GIVEN TO THE CONCRETE. PROCEDURES THAT TRANSFER OIL FROM A COATED AREA SPEED THE RETURN OF SKID-RESISTANCE VALUES TO ORIGINAL VALUES. A TEST TO DETERMINE CAPACITY OF CONCRETE TO ABSORB LINSEED OIL COMPOUNDS IS NEEDED.
