Have you ever looked at a web of highways and wondered how they manage to put down all of that pavement?  America’s veins take quite a lot of asphalt to install, and even more planning.  Not to mention, it takes a ridiculous amount of manpower to get something like a highway paved and ready to go.  That’s why it seems like construction on highways goes on forever–you may not notice it when you’re driving so fast, but that’s a lot of work!  If you want to know what it takes to build a highway road, read on.

The Process of Asphalt Installation For a Parking Lot

Thursday, June 2nd, 2016

No two parking lots are exactly the same. Traffic changes are crucial, because they determine how thick the asphalt will be.

There are many different steps to the process of asphalt installation.  PTG Enterprises has the most efficient one, and follows guidelines that will lay your asphalt correctly.  To help you out, we’re writing our process down so our customers will be able to see clearly just how we do things.

The Importance of Proper Base and Subgrade Construction in Parking Lots

Friday, July 10th, 2015

Aggregate Base Subgrade Parking Lots

As Meghan Trainor sang, “I’m all ’bout that bass.” Well, here at PTG Enterprises, we are all about that base…and subgrade. It doesn’t matter how good the asphalt is if the aggregate base and subgrade are not properly prepared. These are quite literally the foundation of your parking lot. Without a strong foundation, your parking lot simply will not last. If something goes wrong with the foundation, the entire parking lot – or at least a section of the parking lot – could fail prematurely. (more…)

Proper Base and Subgrade Construction for Parking Lots

Friday, July 18th, 2014

A few weeks back, we discussed the Asphalt Installation Process: a quick overview of each and every step. This week, we are going to take a closer look at a single part of the process: Proper Base and Subgrade Construction. When it comes to paving parking lots, roadways, and other asphalt surfaces, there is perhaps no more important step than the base and subgrade. This is the foundation of your entire asphalt surface. If something goes wrong with the foundation, the entire parking lot – or at least a section of the parking lot – could fail prematurely.

Proper Base and Subgrade Construction for Parking Lots

Strength is essential for a long-lasting paving project. And it all begins with the base and subgrade. In fact, 80-90% of the strength of a road or parking lot is provided by the aggregate base.

  1. All underground utilities must be protected or relocated.
  2. Topsoil is removed.
  3. Analyze drainage concerns, soil quality, and traffic patterns.
  4. Low-quality soil should be improved upon by adding granular materials: lime, asphalt, etc.
  5. Remove rocks, debris, and vegetation.
  6. Grading.
  7. Subgrade soil must be compacted to an adequate density. Poor compaction can lead to premature pavement failure.
  8. Next, we calculate the total “base section.” This is the “gravel equivalency” or GE for this area. After the GE is calculated, for flexible pavements, asphalt concrete has a Gr of roughly 2.0 (twice the total strength) for standard use pavements.
  9. The base is placed directly on top of the subgrade, before being spread and compacted to proper thickness levels.

Pavement design is like baking a cake. If you do not follow the recipe, it could spell disaster!

The Asphalt Installation Process

Friday, June 27th, 2014

Asphalt: it’s everywhere, from highways to parking lots and driveways, but many of us take asphalt for granted. When was the last time you stopped and really thought about it? Where does asphalt come from? How is it installed? Well, today is your lucky day. The asphalt experts at PTG Enterprises are going to give you a closer look at the in-depth installation process.

Asphalt Installation
While an experienced crew may make paving look easy, trust us…it’s not!

The Asphalt Installation Process

For the sake of this article, we are going to just assume that the construction area has already been prepared. So let’s dive right in…

  1. After the stone is laid and fine graded it should be covered with the first layer or base course of asphalt to protect the integrity of the sub-base.
  2. Someone will spray or spot apply tack coat material along any concrete gutter pan or sidewalk reveals.While it may not seem like part of the installation process, one man will be responsible for controlling the movement of trucks. And trust us, this is an important job! It’s crucially important that the trucks stay in order and the next one up is always ready to go. The hotter the asphalt, the easier it is to work with.
  3. Finally, the asphalt is dumped to the paver. One man is responsible to make sure the joint lines up with the previous paving pull and another is responsible for determining thickness, grade, pitch and fall.
  4. The ground personnel, known as “Lute Men,” spread / rake high and low spots out of areas that were just paved but need minor adjustments.
  5. The roller man is responsible for the compaction of the freshly laid asphalt. Plate tampers and hand tampers are used in tight areas where pavers cannot go.
  6. Your base course asphalt is usually installed at two, three, or four inches and compacted to between 92 to 97% compaction.
  7. A second base or intermediate course of asphalt is installed IF NEEDED.
  8. The surface course of asphalt is installed at 1.5, 2.0 or 2.5 inches and compacted to between 92 to 97%.
  9. The area is left closed to all traffic for 24 hours and allowed to cure and harden.

Every new construction project will have its own set of specific requirements that run hand in hand with the type of property. It is important to have an experienced asphalt contractor that can handle each unique situation.

The asphalt paving experts at PTG Enterprises have managed hundreds of pavement projects throughout Baltimore, Maryland, Washington DC, and Virginia. You can expect a fair proposal, professionalism, and quality work.

Is it too cold to lay Asphalt?

Wednesday, November 13th, 2013

Is it too cold to lay Asphalt
 

Fall is in full swing and winter is right around the corner. And before the temperature drops below freezing, business owners everywhere have one question; “Is it too cold to lay Asphalt?”

The Answer: Not Exactly…

You see, paving in colder temperatures presents certain challenges not present with warmer weather. The primary challenge is laying and compacting the hot asphalt before it cools. It takes an organized and experienced asphalt crew, like the one found at PTG Enterprises.

So, is it too cold to lay asphalt? It all depends on who you call. Asphalt contractors that are not set up to work fast will run into problems.

Is it too cold to Sealcoat?

Sealcoating, meanwhile, should only be applied if both ambient temperature and pavement temperature are above 50°F and below 85°F. For these reasons, early fall (March to early November) is typically considered the perfect sealcoating season.

“The best time to sealcoat is from daylight savings time to daylight savings time,” explains Patrick Gillen, owner of Baltimore-based PTG Enterprises, a full service commercial asphalt contractor.

Of course, it all depends on the temperature.

Asphalt: The Entire Package

Sunday, November 10th, 2013

AsphaltThe parking lot of your business can say a lot about you. If your asphalt is cracked or badly weathered, it can severely detract from your business. PTG wants to help you make sure that not only does your pavement look great for aesthetics and safety purposes, but that the experience of having your asphalt repaired or renewed is a special and easy one. Read on to see how PTG works to make laying your asphalt a stress free process.

  • Careful grading – If your grading is incorrect, you can find yourself with unwanted water pooling in unwanted places. PTG follows drawings as accurately as possible to accommodate the unique grade of your parking lot.
  • Stone Installation – PTG will make sure that the right type of stone goes in for the type of ground you have. Though sometimes setbacks happen involving undercutting and other surprises, PTG will work hard to keep your construction on schedule. We know it’s important for you to be able to have your business up and running ASAP.
  • Concrete Curbing and Flatwork – Keeping the curb at the right grade for rain management is very important. Avoiding the chance of rainwater beginning to pond or stand will help keep your parking lot safe and water free. We also know how important sidewalks are and will make sure that the sidewalks are strategically placed.
  • Installation – Both the equipment and the man behind the equipment are vital when it comes to installation. PTG takes pride in hiring people who are hard workers and know what they’re doing. The team will work together carefully to ensure that your pavement is perfect.
  • Striping, Signage, and Wheel Stops – This is what your customers will notice the most. There is nothing quite as nice as fresh paint on brand new asphalt. PTG will make detailed, geometrical drawings of the parking lot before actually striping to make sure that the parking lot looks appealing.

For new asphalt as well as asphalt maintenance, PTG will work to give you a top-notch product that you can be proud of.
