Benefits of technology

The invention aims to create an interface that can impact traffic in a gradual and staggered manner, reducing shock and the accompanying drawbacks that come with sudden impact. This gradual impact allows for the distribution of impact forces over a longer period of time.

Problems solved by technology

This means that co-axial wheels of a vehicle will impact the interface simultaneously, resulting in a substantially instantaneous or impulsive impact.
This impact is noisy, and causes a shock both in the vehicle and the pavement, which is uncomfortable at best, and damaging to the pavement and / or vehicle at worst.

Embodiment Construction

[0025]Referring initially to FIG. 1, reference numeral 10 generally indicates a pavement interface, in accordance with the invention. The pavement interface includes a first section of pavement 12 and a second section of pavement 14, and the interface 10 is between the two sections of pavement 12, 14.

[0026]A trailing (or terminating) edge 12.1 of the first section of pavement 12 has a zigzag shape. Similarly, a leading edge 14.1 of the second section of pavement 14 has a complemental zigzag shape, and it abuts the trailing edge 12.1. Thus, a boundary 16 between the two sections of pavement 12, 14 is zigzag-shaped. The boundary 16 extends in a direction transverse to a direction of traffic flow (generally indicated by arrow 18).

[0027]Referring now also to FIG. 2, the boundary 16 includes (in conventional zigzag fashion) a series of interspaced rising edges 16.1 and falling edges 16.2. Between each adjacent rising and falling edge 16.1, 16.2 is an apex 16.3. Each rising edge 16.1 and ...

Abstract

Pavement interface (10) and method of creating a pavement interface. The pavement interface (10) includes a first section of pavement (12) having a zigzag-shaped trailing edge (12.1) and a second section of pavement (14) having a complemental zigzag-shaped leading edge (14.2) which abuts the trailing edge (12.1) of the first section of pavement (12). Thus, a boundary between the two sections (12, 14) of pavement is zigzag-shaped.

Description

FIELD OF INVENTION[0001]The invention relates generally to pavements or road surfaces, and specifically to a pavement interface.BACKGROUND OF INVENTION[0002]The Inventor is aware that pavements are sometimes required to transition from one surface to another. For instance, in pavement re-surfacing, the pavement may transition from the old surface to the new surface (or vice versa). Similarly, it is sometimes required to dig trenches in the pavement to lay cables or pipes. The trench is then re-surfaced.[0003]The interface from one surface to another is almost always linear and usually perpendicular to a direction of traffic flow. This means that co-axial wheels of a vehicle will impact the interface simultaneously, resulting in a substantially instantaneous or impulsive impact. While the profile of the interface is as flat as possible to minimise this impact on the wheels, there is often still at least a small ridge or depression. This impact is noisy, and causes a shock both in the...
