Double Chip Seal on Paving Fabric


The objective of this project will be to study how a chip seal performs when placed on an approved paving fabric, and how it wears and resists reflective cracking from the existing surface and other wear factors. 
Using this information, and with the input of PennDOT, a specification for PUB 447 will allow municipalities to use liquid fuels funds to pay for the installation of this process. 

Maintenance - Project No: ECMS E03718

 Anticipated Outcomes:

Research has been completed. 
Specifications are under final review, and will be added to PUB 447 for the 2021 Construction Season.
