“I love being an engineer because I am always solving problems and challenges, I have the opportunity to do so many different things. Engineering really has given me a great structured thought process which can be used to solve any problem!” – Kristin Sweeney, Director of Operation, US Aggregates
We recently celebrated Engineers Week, and one thing that was common among the engineers at HC+M is that they enjoy problem solving. We asked our engineers their favorite part of their career, when they realized they wanted to be in this field, what made them feel accomplished, and to describe themselves in one word. Watch the video to hear from our engineers!
The International Day of Women and Girls in Science is an annual observance adopted by the United Nations General Assembly to promote the full and equal access and participation of females in Science, Technology, Engineering, and Mathematics fields.
Today, we highlight and celebrate just a handful of many of the incredible women on our team who dedicate their time and experiences with us to continue flourishing as a whole!
Amelia Earhart was More Than Just an American Aviator
Born July 24, 1897
We celebrate Amelia Earhart as a pioneering woman of science, someone who participated in and promoted STEM education, much of it here in Indiana. In 1935, Earhart became a visiting faculty member at Purdue University as an advisor to aeronautical engineering and a career counselor to female students.
Being an Indiana company with deep roots stretching all the way back to 1930, you might imagine the connections with Purdue University are also deep-rooted. We are a company that is involved in construction, materials, chemicals, and environmental services with research and development across all of our businesses. These areas of parallel commonalities to a Purdue University STEM education are just a few reasons why these roots are so deep.
Full Depth Reclamation (FDR) is a cost effective and sustainable rehabilitation technique that combines the entire bituminous pavement thickness and a predetermined portion of the underlying aggregate material into a flexible, homogenous stabilized base layer utilizing an asphalt emulsion to provide mixture cohesion and water resistance. FDR is a solution for rehabilitating roads that have poor structure. The FDR is typically followed with an overlay of hot mix asphalt.
This full depth reclamation project took many parties from start to finish. Milestone Contractors, Inc. submitted the bid, Asphalt Materials, Inc. supplied the engineered emulsion and Heritage Research Group provided the sampling, mix design and quality control.
This particular project was on Hartman Drive in Bartholomew County, Indiana. It consisted of an eight-inch (8″) full depth reclamation on one thousand, one hundred feet (1,100′) of existing recycled asphalt pavement (RAP) road and one hundred – 70 feet (70′) of existing asphalt road. A 3″ hot mix overlay laid in 2 lifts of 1 ½” each was then placed on the new recycled roadway base.
The County collected and placed the RAP at a depth of 8-9” from another project in the area to build the new roadway base. Milestone then pre-pulverized and graded the entire roadway at a depth of 8”. A second pass was made with the reclaimer and the engineered emulsion was injected and the emulsified material was graded and compacted. After the final cure the recycled base was overlaid with two 1 ½” lifts of HMA (Hot Mix Asphalt), striped and opened to traffic.
Asphalt Materials Inc., is a proud member of The Heritage Group and brings nearly 65 years of experience to the asphalt industry and road construction projects. Our teams of professionals are dedicated to creating longer-lasting, safer roads with quality, reliable asphalt materials.
Our family of companies want to ensure we are leaving the world in a better place for future generations. As The Heritage Group continues to expand capabilities and investments in the sustainability space, the AMI team is also focused on sustainability in a number of different areas. We will be reporting on these in future articles.
