A look behind the scenes into the pavement challenges and what options were considered for this paving application method for Champaign County, Ohio Engineer’s paving project. Read below to see why this cold mix paving product was the clear answer for this project.
On August 18th, a Chip Seal project took place in Gaston, Indiana. This project was completed by the Delaware County Highway Department. Chip seals are used to prevent water intrusion into a pavement and create a high friction surface for safety. Chip seal emulsions can be polymer modified to improve aggregate retention and provide for a quicker return to traffic.
Improving the resilience of infrastructure helps advance a more sustainable transportation network.
Pavement preservation is a more cost-effective and environmentally friendly way to extend the life of your roadways and make 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.
An Economic Alternative to Full Reconstruction
Cold Constructed Asphalt Pavement (CCAP®) is a cold mix asphalt that is created by combining aggregate and a chemically modified asphalt and mixing the two ingredients at ambient temperature. The cold mix may be stockpiled for weeks to a few months and then placed using a paver for road repair such as patching potholes or adding a new layer to low-volume roads. A chip seal is often placed over the cold mix.
Chip seals are an application of asphalt emulsion or chemically modified asphalt, followed by a layer of aggregate which is rolled and embedded into the emulsified asphalt. The process may be repeated to create a double or triple chip seal.
Anyone who travels knows the importance of a smooth, safe drive—which is why cracks and potholes can ruin a journey. These obstacles can be caused by issues below the exterior, but applying the right formula to the surface of a road can have a much deeper impact.
Fog Seal Treatments can be a valuable aid to renew weathered asphalt surfaces while also improving the appearance of the surface.
A fog seal is a single application, typically light, of emulsified asphalt to an existing asphalt road surface. This type of maintenance treatment can be a valuable aid to renew weathered (oxidized) asphalt surfaces, improve the surface appearance, seal minor cracks and surface voids, and inhibit raveling.
On July 29th a fog seal project took place in Morgan County, Indiana. The pictures in this article are from that project.
Any day is a beautiful day to recycle pavement. This particular project took place earlier this week in Martinsville, IN with our Cold-In-Place Recycling (CIR) technology. CIR is a cost-effective and sustainable method of constructing a recycled asphalt-bound layer that reduces trucking and construction time and saves natural resources.
With an increasing emphasis on infrastructure, the reuse of valuable existing resources is a critical component in a pavement manager’s arsenal. According to research, the advanced technologies used in recycling and reclamation processes can provide major benefits such as:
The asphalt industry is in a good place, but more work is being done to get even better, more sustainable and resilient if you will. The world’s most recycled material is asphalt. A report from the Federal Highway Administration shows that 80% of the asphalt pavement that’s removed each year during widening and resurfacing projects is reused.
CIR is a process that removes cracks and other pavement distresses. CIR is a rehabilitation technique where pavement is milled, crushed, and mixed in place with a stabilizing emulsion or foamed asphalt and then placed with conventional paving equipment. Roads should be evaluated beforehand for suitability for the CIR process.
Asphalt Materials has been focused on building longer-lasting, safer roads since 1956. We have the full support of the Heritage Research Group Laboratories to help us achieve this objective. We also have extensive knowledge in recycling products and processes, combined with the technical expertise gained from years of experience.

What is an Asphalt Emulsion?
Asphalt Emulsions are a mixture of an asphalt base, water, and emulsifier (soap) that is primarily graded on the curing rate and ion charge. There is interest in the usage of emulsions for several reasons. The first reason is that an asphalt emulsion does not require a petroleum solvent to make it liquid, and in most cases does not require additional heat which helps save energy.
Washtenaw County is located in southeast Michigan. The County seat is Ann Arbor, home of
The University of Michigan Wolverines. The Washtenaw County Road Commission (“WCRC”) is responsible for maintaining 1,653 total miles of primary and local roads along with 598 lane miles of State highways under a contract arrangement with the Michigan Department of Transportation (MDOT).
