Pavement Markers

Expert Raised Pavement Marker & Lens Installation

Penn Line acquired DW Miller, Inc. in 2015, enabling us to add the installation of pavement markers to our growing abilities.

Headquartered in Central Pennsylvania for more than five decades, DW Miller Inc. is ideally positioned to serve 25% of the total lane mileage and 25% of the population in the United States. When considering total job costs and response time, DW Miller provides a significant advantage over contractors from outside the region.

Pre-qualified in PA, MD, VA, and WV for the installation of temporary, raised, and snow plowable raised marking systems from Hallen, Rayolite, and Ennis-Flint; DW Miller has the experience and equipment to provide prime or sub-contract services anywhere in the Mid-Atlantic and Northeast US.

Local Experience

We take pride in hiring a local workforce and ensuring that they have a secure and stable working environment. Despite the seasonal nature of the pavement marking services industry, the average tenure of DW Miller Employees is over 10 years. This means that our clients benefit from a team of experienced professionals who can efficiently and safely complete your project, unlike contractors with temporary or high turnover workforces.

Plan For Success

The pavement marking industry requires specialized equipment, which we ensure is well-maintained and regularly updated. Our focus is to have the newest and most advanced fleet in the business, not just for appearance but also for the safety of our employees and the efficiency of our services. With a modern fleet, we can minimize maintenance-related downtime and provide cost-effective solutions to our customers.

We’re also proud to hire a local workforce and provide them with a safe, steady working environment. In fact, in the routinely seasonal industry of pavement marking services, the average tenure of DW Miller Employees is more than 10 years. The benefit to our clients is a seasoned workforce with the experience to perform your project safer and more efficiently than a contractor with a temporary or high turnover work force.

The pavement marking industry is highly specialized, and so is the equipment. In addition to our commitment to preventative maintenance, all major equipment is placed on a standard replacement cycle. Our goal is to have the latest rolling fleet in the business. It’s not just a matter of aesthetics. A modern fleet helps provide a safer working environment for our employees and lower costs to our customers with fewer “down time due to maintenance” events.

What is a Pavement Marker?

What is an RPM?

A raised pavement marker (RPM) is a safety device used on roads. These devices are usually made with plastic, ceramic, or occasionally metal and come in a variety of shapes and colors. Raised pavement markers include a lens or sheeting that enhances their visibility by reflecting automotive headlights. RPMs can be used to show roadway alignment or to replace or supplement other pavement markings. More frequently, however, retroreflective RPMs are used in conjunction with retroreflective striping for longitudinal delineation. Retroreflective RPMs provide increased visibility at night, especially during rain, to provide wet weather visibility.

What is an SPRPM?

A snow-plowable raised pavement marker (SPRPM) serves the same purpose as an RPM but is designed to withstand the impact of snow-plowing operations. The devices are usually made with a cast iron housing which holds and protects a plastic reflective lens. They are placed into a saw-cut reservoir and are secured to the pavement using epoxy adhesive.
