The leading voice for the crushed stone, ready mixed concrete, sand and gravel, and cement industries' community.
PELA is a 10-month hybrid program with online and in-person educational sessions and networking opportunities.
Careers in the Aggregates, Concrete & Cement Industries
The Pennsylvania Aggregates and Concrete Association (PACA) is the industry’s unified voice, representing more than 200 member companies across the state.
Creating a unified and strong voice for our industry.
PACA monitors and analyzes local, state and federal regulations and advocates for a balanced approach by the regulators.
PACA builds a bridge between our members and our partners at PennDOT, and the Pennsylvania Turnpike Commission along with Pennsylvania’s construction industry to further the use of our materials to the benefit of the commonwealth.
One of the most effective tools in government relations for an industry is a robust advocacy/grassroots strategy.
In the last legislative session, we contributed over $275,000 to our political champions.

PACA offers comprehensive concrete certification programs for ACI, NRMCA, and PennDOT in the central Pennsylvania area.
Membership has its privileges - most of PACA's events are open to PACA members only.
PACA conducts numerous education and training events during the year.
Choose concrete for your next parking lot project.
Streets built with concrete are built to last, consider concrete for your next project.
Concrete's strong, resilient and the choice for your next building or bridge.
PACA works with the National Ready Mixed Concrete Association (NRMCA) to convert your parking lot or building project to concrete without hurting your bottom line.
PACA drives a member-approved strategic plan to increase market share and engages specifiers and owners on the value of concrete in their projects.
This program provides free continuing education to the design and specifying communities. There are currently four courses available, ranging from 30 minutes to 60 minutes focused on the cement, aggregates and concrete industries. You'll receive a certificate of completion once you pass a quiz. The bookmarking feature allows you to leave the course and resume where you left off when you return.
New Enterprise Stone & Lime Co., Inc.
Several years ago Jason Strohm and the team at New Enterprise Stone and Lime Company (NESL) were approached by a company seeking a paving solution at one of their facilities. The issue at hand was the constant heavy loading that dump trucks at the facility were placing on its roadways. Because of its ability to withstand high traffic loadings (350+ trucks per day) Roller Compacted Concrete (RCC) was the choice. That 10” pavement continues to serve the company well.
RCC is an ultra-tough, no-slump concrete that is placed with conventional or high-density paving equipment and usually finished with double-drum rollers. RCC is a perfect marriage of strength, durability, and light reflectivity. It’s constructed without the forms, dowels or steel reinforcing which is typically needed with conventional concrete, making it a strong, fast and economical solution.
In 2019 that same company, citing the need to resolve drainage and dust control issues at another location, again sought the assistance of NESL. Given the success of RCC in its first application, it made sense to incorporate it into this project.
We were pleased that the customer selected RCC for this project and confident it will serve them well for many years.~ Jason Strohm, New Enterprise Stone & Lime Co., Inc.

Over 200 dump trucks daily, each in excess of 70,000 lbs., demand a pavement that will hold up. Given that loading and the sub-grade conditions on site, it was determined that the pavement thickness should be 7”. To simplify the design process NESL reached out to the Pennsylvania Aggregates and Concrete Association for the free Design Assistance Design Assistance ProgramProgram it offers through the National Ready Mixed Concrete Association.
RCC projects may be supplied several ways: pug mill, portable RCC machines, central batch plants, and even dry batch plants. In this case a pug mill was used. Pug mills are an efficient, continuous means of supplying jobs on this order of magnitude.
The pavement was placed using a high density paving machine.
Built into a hillside, ICF construction met the challenge of this project site.
Unique pattern and color make this pervious concrete pad stand out.
The project featured tilt-up concrete construction as well as pervious and roller compacted concrete pavements.
Pervious concrete was selected because it offered a life-cycle cost advantage over asphalt.
Pervious concrete allowed the addition to be built, while maintaining impervious cover limits.
The building features Insulating Concrete Form (ICF) construction.
RCC placement met pavement load requirements and need for quick construction turn-around.
Concrete was the answer for the severe rutting that the street was experiencing.
Project is one of only eight strong walls in the US, and the only one poured monolithically
The program is delivered in one (1) module and it should take approximately 30 minutes to complete. You will receive a certificate of completion once you pass the quiz. The bookmarking feature will allow you to leave the course and resume where you left off when you return.
