Long-Term Pavement Performance Bind Online User Guide

PDF Version (1.68 MB)

FOREWORD

This document presents the user guide for the Long-Term Pavement Performance (LTPP) Web-based tool to select asphalt binders. The LTPPBind Online tool was developed to help State transportation departments, universities faculties and researchers select the most suitable performance-grade binder for a particular site based on the American Association of State and Highway Transportation Officials (AASHTO) M320-10 and AASHTO M332-14 standards.(1–3)

LTPPBind Online provides the option to use LTPP climatic data (virtual weather station or automatic weather station), manual data, or National Aeronautics and Space Administration Modern-Era Retrospective Analysis for Research and Applications climatic data collected globally since 1979.(4,5)

High-temperature (HT) Performance Grade is selected based on a rutting damage model. HT equation is function of target rut depth, yearly degree-days and latitude of site.(6) Low-temperature (LT) PG binder is selected using the algorithm developed from LTPP climatic data. LT algorithm relates surface low pavement temperature to air temperature, latitude, and depth.(7)

This new software tool provides pavement engineers with the ability to select binder grades that are less restrictive, more cost-effective, and agree with Superpave PG concepts.

This document presents the user guide for the Long-Term Pavement Performance (LTPP) Web-based tool used to select asphalt binders. LTPPBind Online was developed to help State transportation departments select the most suitable performance-grade binder for a particular site based on the American Association of State and Highway Transportation Officials (AASHTO) M320-10 and AASHTO M332-14 standards.(1–3) LTPPBind Online provides the option to use National Aeronautics and Space Administration Modern-Era Retrospective Analysis for Research and Applications climatic data collected globally since 1979, LTPP climatic data (virtual weather station or automatic weather station), or manual data.

High-temperature (HT) Performance Grade is selected based on a rutting damage model. HT equation is function of target rut depth, yearly degree-days and latitude of site(6). Low-temperature (LT) PG binder is selected using the algorithm developed from LTPP climatic data. LT algorithm relates surface low pavement temperature to air temperature, latitude, and depth(7).
