      abstract = {Weigh-in-Motion sensors and environmental and structural  instruments are being used by many state departments of  transportation not only to monitor traffic, but also to  evaluate the effect of different factors including traffic,  temperature and strain on the life of pavement. A  significant amount of information on instrumented test  sections is available from test sites such as MNRoad, VA  Smart road and NCAT, which continue to provide valuable  information regarding different aspects of pavement design  and performance. All pavement sections, however, are  traversed by unique combinations of traffic during distinct  temperature conditions. While general conclusions from an  instrumented asphalt pavement test section in one state are  applicable to other states, the unique combinations of  temperature and traffic in any state call for  state-specific data, such as seasonal load restrictions,  when making policy decisions which impact the life of  pavement, such as seasonal load restrictions. Many miles of  low to medium volume roads in the state of Maine are  traversed by heavy trucks, a large percentage of which  transport logs for the forest product/paper industry, and  these trucks have unique combinations of axle/wheels and  trailers that are not commonly found in other states.  Additionally, Maine experiences a pronounced fluctuation of  temperature throughout the year. This study gathered  traffic, environmental and pavement strain data on a  section of Route 15 in Guilford, Maine with the following  objectives: 1. To determine the traffic type and load  distribution across different months; 2. To develop a model  to predict pavement temperature at the location of critical  strains; 3. To evaluate the effect of temperature on  tensile strain in an asphalt pavement layer; 4. To develop  a policy for placing and lifting the State of Maine’s  seasonal load restrictions. This paper presents a sample of  the data gathered, the analysis method employed, and  suggests a systematic approach to using the data to  determine appropriate times for placing and lifting of  seasonal load restrictions based on environmental  conditions, to minimize damage to the pavement and maximize  pavement life. Since the data and observed performance can  also be used to estimate the contribution of traffic in  different seasons toward the damage of the pavement, both  can be used to approximate the life expectancy of a  pavement through rational means.},
