A View from the Road—May 2017

Welcome to Paving Season
The graph below is an update of one our previous Director, Lynne Irwin, produced in 1993. It is based upon discussions we had over the years. It shows the chances of your paving success based upon typical weather conditions for New York State. The solid line shows the probability of success for work with asphalt emulsions, that is, chip seals, micropaving, cold mix, and the like. The dashed line shows the probability of success for hot mix asphalt paving. The closer to the middle of the summer, the better your chances the pavement will last as long as you expect.
The hot mix season 'starts' a little sooner, and 'ends' a little later, but it is still best to pave closer to the middle of the paving season. You can pave late or early, but the risk of failure goes up dramatically. The graph illustrates why we recommend the following for paving:
This, of course, assumes you build the pavement properly. More details on these operations can be found in our Asphalt Paving Principles and Pavement Maintenance workshops or by coming to the Highway School next month.

NYSDOT, in cooperation with the Cornell Local Roads program, respectfully requests that you complete a survey regarding the use of the NYSDOT Bridge Data Information System (BDIS) software. BDIS is used for bridge inspection purposes and is a web-based tool available to bridge owners for accessing all highway bridge inventory, inspection, and load rating related information.
The survey will take only a few minutes to complete. Your response to this survey is very important, as it will be used to address communication protocols, training needs and software updates relative to BDIS. We appreciate your response by May 8, 2017.
If you have any questions, please contact firstname.lastname@example.org.
