 Print this Article | Send to Colleague
By the time you read this article the proposed TxDOT Asphalt Pavement Specifications should be undergoing their second round review. As you should know by now these specifications underwent an intense first-round review by Kyle Swaner, TXAPA Vice President of Technical Programs, and the TXAPA Asphalt Specification Committee. Mr. Swaner, TXAPA President Derek Angel and David Kopp, TXAPA Director of Business Relations, joined the AGC Asphalt Specification Committee to meet with Dale Rand, Darren Hazlett and Gisel Carrasco from TxDOT to discuss the specifications shortly thereafter. Mr. Swaner and President Angel were leaders in this meeting trying to work with TxDOT to have specifications developed that are fair to both industry and TxDOT and specifications that will help to produce high quality long-lasting asphalt pavements for the citizens of Texas.
As a reminder these Special Specifications are proposed to replace asphalt pavement specification items from the 2004 TxDOT Specification book and their associated special provisions. In particular these special specifications are intended to replace:
- Item 340 Dense-Graded Hot-Mix Asphalt (Method)
- Item 341 (Special Specification 3224) Dense-Graded Hot-Mix Asphalt (QC/QA)
- Item 342 Permeable Friction Course (PFC)
- Item 344 Performance-Designed Mixtures
- Item 346 Stone-Matrix Asphalt
These special specifications included many of the changes initially made in Special Specification 3224 as well as additional changes that are specific to each item. For the second round they also include changes made specifically due to TXAPA feedback.
Mr. Swaner is currently coordinating TXAPA comments for the second-round review. If you have any comments that you wish to provide on these proposed special specifications please give Mr. Swaner a call at (512) 312-2099 or send him an email at kswaner@texasasphalt.org.
