Abstract:

A section of US-23 near Chillicothe, Ohio, has been used as a test pavement for the past seven years. Variables included in the test section are slab length, type of subbase, saw-cut configuration, type and coating of dowel bars, and skewed joints. Both hand and electronic measurements of horizontal movement have been made. The hand measurements, made monthly, gave the long-term movements. The electronic measurements were continuous readings taken for one-week periods for each set of joints. Enough data have been collected to set up a computer program on a statistical basis to interpret the results. The results show that the short-term movements are greater than the long-term movements. The short-term movements are as great as 0.25 in (6.44 mm) regardless of whether the slab length is 40 or 21 ft (12.2 or 6.4 m). The long-term movements are much smaller and are almost directly proportional to slab length. It is recommended that the preformed seal be designed for the long-term movements but be able to accommodate the larger short-term movements as an upper limit. The bond between the seal and the joint face should be able to take some tension as a further guarantee of holding the seal in place in case of large joint openings. (Authors)
