Open to the environment: Texas looks to update test, specs for chip seals

Texas' temperature and landscape variances over a vast area can make roadway maintenance very difficult, and when historical specifications are used with maintenance binders, many shortcomings may arise. As a result, there has been an effort to modernize the chip-seal binder specifications using the performance-grade (PG) binder specification for asphalt concrete as a model, developed in conjunction with the national Strategic Highway Research Program (SHRP). Details of the new surface performance-grade (SPG) specification for use in selecting and grading chip-seal binders, sponsored by the Texas Department of Transportation, are presented in this article.
