Runway Grooving

Grooving, a method employed to enhance the co-efficient of friction on wet surfaces, has established itself as the most economical and effective solution in the field of aviation construction and maintenance. This technique is particularly prevalent in airfield grooving, where it serves to augment the friction of a wet runway by facilitating the removal of surface water.

Jointline Limited, a company with extensive experience in the global arena, specialises in the installation of anti-skid grooving on both asphalt and concrete runways. Their expertise is not confined to airfields alone; the application of anti-skid grooving extends to highways, providing additional surface grip and enhancing road safety.

The process of airfield grooving entails the precise saw cutting of horizontal grooves into the runway’s surface. This intricate procedure aids in the rapid dissipation of water, thereby increasing surface friction and substantially reducing the risk of aquaplaning. The resultant effect is a marked improvement in the take-off and landing distances of aircraft, a factor that has been corroborated by rigorous testing conducted by NASA. Such tests have demonstrated that a grooved runway can achieve a co-efficient of friction that equates to 85% of that when dry.

Jointline Limited’s approach to anti-skid grooving is both innovative and comprehensive. Utilising the latest “Cushion Cut” machine, they are able to provide grooves to the required centre, pitch, and depth specifications, while simultaneously vacuuming up the resultant spoil. Recognising that each project is unique, they meticulously identify the correct depths of grooves and groove spacing to optimise water dissipation efficiency for the specific surface in question.

The company’s commitment to excellence is further evidenced by their employment practices. Only operatives possessing the requisite ability and experience are engaged in these contracts, ensuring that the highest standards of quality and safety are consistently maintained.

In conclusion, grooving has emerged as a proven, cost-effective method to increase the co-efficient of friction on wet surfaces. Its application in airfields and highways by companies like Jointline Limited reflects a commitment to safety, efficiency, and innovation in the civil engineering, highways line marking, and aviation construction and maintenance sector.
