Abstract

The AASHTO seasonal and temperature adjustment models do not take into consideration state specific conditions. New Jersey Department of Transportation initiated a study with an objective to calibrate the AASHTO models, or to develop new ones that will take into consideration New Jersey specific conditions. To achieve the objective, twenty-four pavement sections were instrumented and nondestructive testing (NDT) program is being conducted for a period of two years. The main task of the instrumentation is to monitor environmental parameters: air and pavement temperature, moisture, frost/thaw depth and rainfall. Seismic Pavement Analyzer (SPA) and Falling Weight Deflectometer (FWD) are used to evaluate the pavement structural response and its properties on a monthly basis, except during the spring thaw period when it is on a bi-monthly basis. The models will be developed through a two-stage process by performing statistical analyses, such as analysis of variance (ANOVA) and regression analysis. This paper concentrates on pavement evaluation and model development based on SPA results using different seismic tests, including Ultrasonic Surface Wave (USW), Impulse Response (IR), and Spectral Analysis of Surface Waves (SASW). Correlation of environmental variables and pavement properties is also presented.

Seismic Pavement Evaluation in Development of Seasonal Variation Models of Pavement Properties

New York, New York

The AASHTO seasonal and temperature adjustment models do not take into consideration state specific conditions. New Jersey Department of Transportation initiated a study with an objective to calibrate the AASHTO models, or to develop new ones that will take into consideration New Jersey specific conditions.
