Asphalt Concrete – AC
Often times the most expensive part of asphalt maintenance is asphalt repairs. The high cost of materials, the challenge of finding a dump site, and increasing fuel prices make the cost of repairs hard to predict and control. GBR PAVING incorporates the latest technologies (such as grind load machines), as well as unique relationships with suppliers to give you a distinct advantage in scheduling and lowest cost of ownership. GBR PAVING is one of the complete pavement maintenance firms, with over 20 years in the business, we are exceptionally qualified to design, scope, and build the most cost effective solutions for your budget. We can provide scope that will ensure a quality bid process. Long term planning solutions are just one of the advantages you get with GBR PAVING and our asphalt crews can handle any size repair job, including:
- Remove and Replace
- Deep Lift Patching
- Trench Repairs
- Pulverization in Place
- Asphalt Berms
- Grind and Load

Petromat
Petromat, a brand name for what is properly termed Pavement Reinforcement Fabric (PRF) Petromat is a non-woven polypropylene fabric. When used in combination with an asphalt tack coat, the Petromat System forms an asphalt membrane interlayer within the pavement section.
This layer acts as a barrier to surface water infiltration and limits softening of the sub grade and freeze-thaw damage, which could otherwise occur. The Petromat membrane interlayer also absorbs stresses, improving resistance to pavement fatigue and reflective cracking.
Its purpose is to retard crack reflection in asphalt pavement overlays, and to retard water penetration into the pavement’s sub-grade when cracks reappear, it is not a cure-all for cracks in asphalt pavement. The owner should expect to see some hairline reflective cracks (cracks above where cracks existed in the prior surface) within the first year of installation. The cracks will increase over time, but the water-retardant properties of the PRF will keep surface run-off out of the structural asphalt base (sub-grade).
What is Effective?
Is it Hazardous?
Every driveway is different and factors such as surrounding elevations, drainage and use of paved surface can help determine the correct course of action. Please contact GBR PAVING for an appointment with one of our asphalt professionals to determine the correct solution for your project.

Asphalt Milling
A large machine, called a cold planer, slowly drives down the street, trailing a drumhead covered in spikes that dig into the asphalt, rip it up, and capture it. A series of conveyor belts carry the milled asphalt to waiting trucks, and then the reclaimed asphalt is taken back to the plant to be mixed in with new paving.
The milling process leaves the sub-base intact so new asphalt can be installed over top, creating a new, smooth surface that saves both time and money on a paving project. Moreover, recycling the old top surface and by passing a full reconstruction boasts environmental benefits.
Milling is also employed when a roadway has become too elevated, due to repeated repaving, and needs a few inches taken off the top.
Asphalt Pulverizing
Pulverization leaves several inches of ground-up asphalt where old asphalt paving used to be. This makes it possible to then reform that asphalt into a solid surface, through stabilization.
Asphalt Stabilization
After a day or so to harden, the result is a rebuilt asphalt road or driveway – made using a minimum of new material, but every bit as strong and reliable as when the road was laid in the first place. Between pulverizing and stabilization, it’s possible to quickly replace asphalt with a minimum of cost, effort, and traffic disruption.
GBR PAVING uses these and other asphalt processes because of their environmental benefits. To find out more about these asphalt processes Contact GBR PAVING, to learn more about asphalt paving or to have your parking lot, road or driveway paved.
Asphalt Cracks
Cracking in asphalt/concrete is a phenomenon that pavement design and maintenance engineers have had to contend with for years. Fatigue cracking is the principal consideration in pavement maintenance. Cracks are inevitable, and neglect leads to accelerated cracking and/or potholing, further reducing pavement life and serviceability.
The problem of cracks is handled in many ways, ranging from pavement maintenance activities, such as surface treatments (seal coating or road slurry and hot rubberized crack sealing) to full-scale pavement rehabilitation projects, such as resurfacing. Maintenance departments/Property management companies bear most of the burden of dealing with cracks. Agencies with sufficient funding are often responsible for adding a few more years of serviceable life to deteriorated pavements, through preventative or routine maintenance, or both.
One of the more common options exercised by city or state maintenance departments is crack sealing. This operation has been conducted for many years, generally on a routine basis. However, only in the last two decades has its potential benefit as a preventive maintenance tool been realized.
Hot applied rubberized crack sealants should not be confused with cold applied Latex crack fillers that are non-elastic. Due to their non-elastic nature, as seasonal temperatures change, causing the asphalt to expand and contract, these cold applied fillers will re-crack prematurely causing further asphalt deterioration.
