摘要：	This chip seal used for shoulder rumble effect produced an effective audible response with a noise difference from the driving lane to the shoulder of 3.8 db. The chip seal also produced a highly visible delineation between the shoulder and the driving lane. This type of treatment has three benefits. Two of the benefits are directly safety related, rumble effect to notify the errant driver that they have entered the shoulder and the visual effect given by the well delineated shoulder. The third benefit is a temporary fix to a badly deterioriating shoulder without the cost of major reconstruction until a later date. Rumble strips rolled into the shoulder during repaving were very noticeable when leaving the driving land and appear to be an effective safety item on rural roadways where run-off-road accidents are common. Rumble strips can be placed with little problem during construction if asphalt temperatures are monitored during project startup.
