Asphalt Surfacing

Roymire Roads & Civils has reliable equipment as well as back up from reputable supplies locally to be able to meet client needs.

Depending on the temperature at which it is applied, asphalt is categorized as hot mix asphalt (HMA), warm mix asphalt, or cold mix asphalt.

Hot mix asphalt is applied at temperatures over 300°F (150°C) with a free-floating screed. Warm mix asphalt is applied at temperatures of 200–250°F (95–120°C), resulting in reduced energy usage and emissions of volatile organic compounds. Cold mix asphalt is often used on lower volume rural roads, where hot mix asphalt would cool too much on the long trip from the asphalt plant to the construction site.

Road Maintenance

Patching Pothole repairs, crack sealing, Parking areas and humps. With state of the art equipment like Hot dogs crack seal machines, bomag rollers swacut machine. ETC. A road maintenance depot is a depot used by road maintenance agencies for storing works equipment and organising maintenance operations. Road maintenance depots can range in size from small shed storing just a few pieces of equipment to vast buildings housing computer and closed-circuit television systems, allowing operators to monitor conditions across the road network. Road maintenance depots carry gear for a number of tasks, including road works, snow removal…

 

Speed Humps

Speed humps are asphalt mounds placed on roadways for the purpose of slowing traffic. Speed humps are different than speed bumps, which are commonly seen in parking lots or on private streets.

Why are speed humps desirable?
Speed humps can help control speeding on local neighbourhood streets: They can reduce average speeds by as much as 7 mph. Unlike traditional police enforcement, speed humps provide continuous service. They may also help discourage cut-through traffic by diverting it elsewhere.

Humps are placed across the road to slow traffic and are often installed in a series of several humps in order to prevent cars from speeding before and after the hump. Common speed hump shapes are parabolic, circular, and sinusoidal. Generally, speed humps are 12 to 14 feet (3.7 to 4.25 m) in length and span the width of the road. The height of humps ranges from 3 to 4 inches (7.5 to 10 cm). The length and height of the speed humps determine the speed at which traffic will travel over the devices.

 

Slurry Seals

mSlurry Seal is a coldix blend of high quality crushed aggregates, asphalt emulsion, water and mineral fillers, mixed together according to a pre-determined mix design from a laboratory. It is applied to an existing surface, such as surface treatment or pavements, that are still in fair to good condition, as a means of a cost-effective preventative maintenance. It reduces deterioration by sealing, prevents further oxidization, corrects ravelling and provides or replaces a high degree of skid resistance. Slurry Seal is applied with a spreader box, which is connected to the slurry mixing unit. The box is the width of a single lane, allowing a uniform spread of material in a single pass.
