Petrotac Case Study

Scenario

Interstate 70 had become a very heavily traveled interstate highway running East to West. The enormous increase of population in the Indianapolis area had taken its toll on a stretch of the interstate that runs through Greenfield, IN.

The pavement has basic Portland Cement Concrete with 5-inches of asphalt placed on the top. The asphalt was seriously deteriorated caused by surface water infiltration that weakened the foundation layers of the pavement and enabled fines pumping, erosion, and freezes then thaw damage. To reconstruct the roadway, the asphalt had to be milled down to the original PCC surface and then replaced.

Petromat and Petrotac Installation at Jobsite

The Solution

To guarantee the restoration would offer long-lasting benefits, INDOT wanted results that would alleviate cracking from the PCC pavement reflecting up into the new overlay. The really bad PCC joints were mended and the fairly stable joints were covered with strips of Petrotac® to increase the life of the replaced overlays. Petrotac® is a self-adhering paving membrane interlayer that is designed to decrease reflective cracking through stress absorption.

Along a 7.5 stretch of the interstate, other joints and cracks were filled. They used a primer on the milled surface and the Petrotac® strips and applied it over some joints and cracks on the PCC pavement. The contractor lightly rolled the installed Petrotac strips to increase adhesion to the pavement.

Overall PETROMAT® Enviro Performance

There were a number of minor fragmented joints and cracks that remained.

Petromate® Enviro was included in the design to provide a total pavement moisture barrier and stress absorbent interlayer. INDOT had used Petromat Enviro earlier on an area of Interstate 65. Everyone was pleased with its ability to extend the life of the pavement. INDOT was impressed by the paving fabric's ability to be milled and recycled.

A tack coat of 0.26 gallon/square yard of PG64-22 was sprayed on the milled pavement and over the Petrotack strips. Afterward, Enviro was applied and the intermediate HMA course was placed. Enviro is an excellent choice for installation over milled surfaces due to its ability to conform to the rough surface and elongation. Lastly, the wearing surface course of asphalt cement was placed to complete the restoration.

The plan for using Petrotac over the worst joints and cracks followed by a full-width installation of Petromat Envior offered the pavement a significant effect to greatly extend the life of the replacement overlay. Also, the pavement foundation layers will regain strength, prevent erosion, and avoid freeze and thaw damage.
