Hot and Warm-Mix Asphalt

Hot Mix Asphalt

Over 93 percent of the paved roadways in the US use asphalt pavement. They are durable, quick to install and open to traffic, and they are highly recyclable. The public prefers asphalt pavements because they ride smoother and are quieter than concrete pavements. Our knowledgeable and highly experienced team is always available to help customers work through challenging technical requirements.

Three Peckham subsidiaries – Peckham Materials Corporation (PMC), Wm. E. Dailey, Inc. and Dutchess Quarry & Supply – produce hot mix asphalt (“HMA”) for the residential, commercial and heavy highway markets. A network of production facilities located throughout the Hudson Valley Region of New York State and Southern Vermont is the backbone of the operation. These plants provide exceptional production capacity, flexibility and reliability and operate in compliance with all environmental regulations. Peckham Materials HMA plants are highly automated, modern production facilities equipped with on-the-scale receipt printing technology. In most plants, the driver does not ever have to leave his truck! The PMC team knows that customer service is just as important as price. Saving customers valuable time and money has and always will be a top priority at Peckham.

In addition to our pioneering work with Warm Mix Asphalts we have developed advanced designs that help mitigate rutting as well as porous pavement that help mitigate runoff in environmentally sensitive areas. Working Certified technicians and modern laboratory equipment allow each facility to maintain strict quality control standards.

In addition to our stationary HMA plants, PMC also operates a portable hot mix drum plant. This plant allows PMC to extend the best service to remote communities as well as high production requirements on major construction projects.

Warm-Mix Asphalt

Warm-mix asphalt (“WMA”) is a relatively new product that is rapidly gaining in popularity. We have achieved reductions in mix temperatures of 50 to 75 degrees Fahrenheit. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases. Warm mix asphalts also reduce worker exposure to fumes. Engineering and construction benefits include better compaction of pavements; the ability to pave at lower temperatures, extending the paving season; and the ability to recycle at higher rates. WMA is produced using the same gradation and design methodologies as conventional hot mix asphalt. WMA is transported and placed using the same equipment.

Ongoing research is being conducted to evaluate whether WMA pavement will last even longer than HMA pavement by reducing aging of the pavement during the production process. The liquid asphalt is exposed to less heat which reduces oxidation so the pavement retains greater elasticity and is less susceptible to thermal cracking during cold weather. WMA is a very promising product and should be considered for any new construction projects with a strong commitment to sustainability.

Paving with WMA requires no special equipment and the Peckham professionals are well-versed in the ecological and economic benefits of using this product. During the manufacturing process, experts regulate the additive and test the material. Finally, they assess its durability against a set of strict quality guidelines that guarantee the best product and service for every job.

WMA also has usefulness in cold weather paving where conventional HMA would be inappropriate. Many of the advantages gained when WMA is produced at regular hot mix temperatures are particularly beneficial for cold weather conditions. Moisture susceptibility can be a complicating factor, and our engineers may recommend use of anti-strip agents to mitigate these concerns.
