Ambient Temperature Paving
Recycling asphalt and aggregate roads with Earthbind® is a very simple and cost-effective method.
- The old roads can be pulverized with a rotary mixer and transported to the portable crush site or roto mill direct transfer into dump trucks delivering to the portable crushing and process site for size reduction.
- Reduce the size of material to the requested size, (3/4’’ minus), for example for pug mill processing.
- Load the computerized pug mill injecting Earthbind® EBS-RA, or Portland cement if requested.
- The trucks are automatically loaded to truck using on board scales to ensure maximum legal loads delivered to each departing truck.
- All paving is with common pavers and compaction equipment.
Dry time is generally quicker than hot asphalt and with no toxic fumes that come from hot asphalt. - On site portable equipment reduces haul off as well as the cost of hot asphalt and related delivery charges for significant savings.
Ambient Temperature Paving: A Cost-Effective and Eco-Friendly Solution for Road Construction
Are you looking for a way to improve your road construction projects with less cost, less emissions, and less hassle? If so, you might want to consider ambient temperature paving, a process that uses recycled materials and Earthbind® products to create durable and smooth asphalt surfaces.

What is Ambient Temperature Paving?
Ambient temperature paving is a method of road construction that uses a pug mill mixer to blend recycled asphalt millings or type #2 base materials with Earthbind® EBS-RA, a biodegradable and non-toxic stabilizer. The resulting mixture is then paved and compacted using conventional equipment and methods.
The advantages of ambient temperature paving are:
- It uses recycled materials that would otherwise go to waste, reducing the need for new aggregates and hot asphalt.
- It reduces the emissions from trucking materials to and from distant facilities, as the pug mill mixer and crusher can be set up near the project site.
- It produces asphalt that is ready to pave at ambient temperature, eliminating the need for heating and maintaining high temperatures during transport and paving.
- It allows for faster return to traffic, as the asphalt sets quickly and does not require cooling.
- It creates a solid matrix of aggregates that binds the fine particles and prevents water infiltration, improving the strength and durability of the pavement.
What is Ambient Temperature Paving?
The process of ambient temperature paving involves the following steps:
- Grinding and stockpiling the asphalt millings from roads that are scheduled for repaving. The millings are then delivered to a track infield impact crusher that reduces them to the desired size. For example, one project in New Jersey asked for a 7/8” minus.
- Mixing the crushed millings or type #2 base materials with Earthbind® EBS-RA in a pug mill mixer. The pug mill mixer can produce up to 300 tons per hour, depending on the paving crew’s capacity.
- Paving and compacting the mixture using standard equipment and methods. The product temperature during paving was 77 degrees in the New Jersey project.
- Opening the road to traffic as soon as the pavement is stable. The setting time depends on the ambient temperature, humidity, and traffic load.
