LTPPBind

LTPPBind is a Windows-based software program developed by LTPP to help highway agencies select the most suitable and cost-effective Superpave asphalt binder Performance Grade (PG) for a particular site. Based on the original binder selection software SHRPBind, LTPPBind features a database of high and low air temperatures (minimum, mean, maximum, standard deviation, and number of years) for U.S. and Canadian weather stations, along with several modifications that provide users with the ability to:

  • Select PGs based on actual temperature conditions at their site and at the level of risk designated by their highway agency.
  • Use either the original SHRP or LTPP's revised temperature models for determining a site's binder PG.
  • Adjust PG selection for different levels of traffic loading and speed.

LTPP's revised temperature models that form the basis for LTPPBind were developed via an LTPP data analysis project. The research report from the project is entitled, LTPP Seasonal Asphalt Concrete Pavement Temperature Models (FHWA-RD-97-103). Two additional SHRP reports contributed to the development of LTPP Bind ver. 2.1. These reports are available for download on the TRB website. SHRP-A-637 - Analysis of Integrated Model of Climatic Effects on Pavement and SHRP-A-648A - Weather Database for the Superpave Mix Design System.
