Paving the Future: Montana Highway 200

Co-authors: Andrew Eicher & Naarah Holloway

Road managers know that the longitudinal joint is the first part of the pavement to fail. As a road’s most permeable part, this joint is susceptible to the elements. Air and water work down through this gap causing the joint to deteriorate, crack and pothole. And when the longitudinal joint fails, the rest of the road soon follows—triggering the need for even more maintenance.

Central Kentucky Regional Airport Project Makes Kentucky 24th State to Use VRAM

The first void reducing asphalt membrane (VRAM) project was completed in the state of Kentucky, marking 24 states and the District of Columbia that use VRAM to save infrastructure funds. VRAM is applied at the location of the longitudinal joint prior to paving to fill a portion of the voids. This greatly reduces permeability and protects the joint area, resulting in longer pavement life.  

This project was completed on July 28, 2023, at the Central Kentucky Regional Airport in Madison County, Kentucky.

AMI supplies high-quality materials for CCAP® in Morgan County, Indiana

Agencies are seeking cost-effective and sustainable solutions to make roads last longer. This is why the Heritage Research Group (HRG), Asphalt Materials Inc. (AMI), Milestone Contractors, and US Aggregates are all working together in a One HC+M project to figure out how to make the strongest, most sustainable, and cost-efficient asphalt mix in the Midwest region. One solution the team has found that is not only cost efficient, but sustainable and durable, is Cold-Construction Asphalt Pavement (CCAP®).

AMIGUARD™ RPE Helping Create Longer Lasting, Safer Roads in Monroe County

What is RPE?

It is important to plan ahead when considering pavement protection and preservation techniques. Proactive pavement protection is an infrastructure investment, but it can also help ensure safety for drivers. One important aspect of pavement preservation is to reduce air voids. When air voids are high, permeability is high, which adversely affects pavement life. This is why using a Rapid Penetrating Emulsion (RPE) soon after pavement construction can be a wise investment.

Cold Constructed Asphalt Pavement Project in Ohio Helping Roads Last Longer

Small’s Sand & Gravel: 10229 Killduff Road CCAP® Patch Project

Pavement preservation is a cost-e­ffective and environmentally friendly way to extend the life of roadways which helps public funding go further. A pavement preservation strategy is proven to produce fewer greenhouse gas emissions, expend less energy, and give faster application times than the alternative conventional approach, in addition to being cost-effective.
