Hot In-Place Recycling
The Cost-Effective Process for
Sustainable Infrastructure

Quality road resurfacing at a fraction of the cost of traditional methods.

Building and Recycling Roads for Over 95 Years

Hot-In-Place Recycling is an on-site, in place, pavement rehabilitation method that consists of heating, scarifying, mixing, placing and recompacting existing bituminous pavement. As industry leaders, Gallagher Asphalt’s commitment to Safety, Quality, and Innovation allows us to set the standards in the world of Hot In-Place Recycling (HIR).

Invest in a Long Term Solution, Not a Quick-Fix

When you recycle your roads, you’re improving the durability and resilience of your infrastructure.


As costs rise rapidly, Hot In –Place recycling allows you to achieve greater road rehabilitation while staying within your budget. Maximize the value of your existing materials for optimal and budget friendly results, ensuring a high-quality outcome of your roadway.

Extended Road Life

Hot In-Place provides opportunity. Using the same budgeted dollars as usual. Hot In-Place can extend your road’s life while allowing you the freedom to perform appropriate Asset Management on other areas of the community. When we are complete, your roads will live for the same lifespan as normal roadway fixes, but you have more money in your budget to manage other assets.


We complete a lane-mile a day with no road closures. Flaggers direct traffic around our operation so the road is never closed. Once we come onsite, we do not leave until the job is complete.


The HIR process reduces the number of trucks needed compared to a “traditional” mill & overlay process. Reducing up to 80% of trucks on a project decreases traffic congestion for motoring public, cuts down public complaints, and mitigates scheduling conflicts by reducing the number of steps to get your project completed.


HIR reduces the carbon footprint by 28% by having fewer trucks on the road hauling materials, and less new material production.
