Long-Term Pavement Performance (LTPP) Seasonal Monitoring program (SMP) instrumentation was installed in pavement sections at the Ohio SHRP Test Road. The pavements are monitored for the seasonal variations of moisture, temperature and frost penetration. Data from the instrumentation is subjected to quality checks and prepared for uploading to the FHWA Information Management System (IMS). Findings from the testing are to be incorporated into future pavement design procedures.
One of the functions of the FHWA (Federal Highway Administration) integrated model of climatic effects on pavements is simulation of the pavement temperature. The model was applied to certain field cases for which pavement temperature measurements were available. The model seems to be capable of providing a reasonable estimate of pavement temperature if realistic input variables, particularly appropriate thermal properties, are utilized. A sensitivity analysis was performed to evaluate the influence of variations in the air temperature, solar radiation, percent sunshine, and thermal properties on the calculated pavement temperatures.
About 90 percent of this excessive heat is due to buildings and pavements that absorb and store solar heat (According to the Green Buildings Council). The only reference that focuses specifically on pavements, Pavement Materials for Heat Island Mitigation: Design and Management Strategies explores different advanced paving materials, their properties, and their associated advantages and disadvantages. Relevant properties of pavement materials (e.g. albedo, permeability, thermal conductivity, heat capacity and evaporation rate) are measured in many cases using newly developed methods. - Includes experimental methods for testing different types of pavements materials - Identifies different cool pavement strategies with their advantages and associated disadvantages - Design and construct local microclimate models to evaluate and validate different cool pavement materials in different climate regions
Pavement Engineering: Principles and Practice examines a wide range of topics in asphalt and concrete pavements from soil preparation and structural design to life cycle costing and economic analysis. This updated Fourth Edition covers all concepts and practices of pavement engineering in terms of materials, design, and construction methods for both flexible and rigid pavements and includes the latest developments in recycling, sustainable pavement materials, and resilient infrastructure. New and updated topics include material characterization concepts and tests, pavement management concepts, probabilistic examples of life cycle cost analysis, end-of-life considerations, waste plastic in asphalt, pervious concrete, pavement monitoring instrumentation and data acquisition, and more. The latest updated references, state of the art reviews, and online resources have also been included.
"This report summarizes the results of research to evaluate, calibrate, and validate the Enhanced Integrated Climatic Model (EICM) incorporated in the original Version 0.7 (July 2004 release) of the Mechanistic-Empirical Pavement Design Guide (MEPDG) software with measured materials data from the Long-Term Pavement Performance Seasonal Monitoring Program (LTPP SMP) pavement sections. The report further describes subsequent changes made to the EICM to improve its prediction of moisture equilibrium for granular bases. The report will be of particular interest to pavement design engineers in state highway agencies and industry ..."--Foreword.
