SOMETIMES YOU JUST GET A SWIFT KICK IN THE “ASS-PHALT.”
How about an oil spill in your parking lot? This is exactly the case at this facility in North Richland Hills…a suburb of Dallas and Fort Worth, TX. Our Superhero, Orange Cone Man, is called “The Proud Protector of People with Pavement Problems” and he was really needed on this site. The problem here was compound…oil spills create a “hazardous material” scene and, the oil will penetrate the asphalt and dissolve it.
Pavement Services Corporation, experts in asphalt pavement repair, was called to this site after the oil soaked asphalt pavement had been removed and safely disposed of. Typically, we would recycle this pavement in the repair process, but since it was saturated with oil, the material had to be disposed of according to HazMat Procedures. As you can see, this left a big mess and a large area in need of repair. No problem for one of PSC’s expert paving crews, equipped with the proper equipment and well-trained personnel.
PLAN OF ATTACK…
Our plan of attack was to enlarge the excavated area by running our Asphalt Mill Machines around the perimeter of the repair area. This allows our crews to take the completed repair beyond the weak edges back into solid pavement for structural integrity, and create square edges for aesthetic appeal, as well. We could also use the “spoil” materials from the surrounding edges to fill the excavated void area, lessening the need for the importing of new base materials to bring the entire repair area to proper grade. Once all milled asphalt and base materials were in place, the crew added Portland Cement to the entire area and mixed the materials one more time with the milling machine, creating a Cement Treated Base. Water is added to the materials, as needed, to allow for proper compaction and to activate the cement so it will harden the materials and create a good, sturdy foundation for the asphalt pavement surface course.
Once the base work was complete and allowed to cure, the crew then laid the asphalt surface course over the repair area to complete the process. At that point, the customer was alerted that the repair process was complete and traffic would be allowed back on the area the next day. So, with the problem solved and the customer satisfied, the Orange Cone Man jumped in his Cone-mobile to go proudly serve another person with pavement problems.
