Description

  The present invention relates to a method for confirming the opening of traffic on a paved road, and more specifically, when opening a paved road after laying and constructing any one of an asphalt paved road, a concrete paved road, and a resin paved road. In particular, the present invention relates to a traffic opening confirmation method on a paved road, which can easily confirm whether or not the paved road has been cured to a hardness suitable for opening.

  Conventionally, after laying and constructing any one of asphalt paved roads, concrete paved roads, and resin paved roads, traffic is opened on the paved roads so that no dredging occurs when the vehicle travels. Time was a problem.

  There is no special standard for the judgment of the opening time of paved roads as described above. For example, steel balls and golf balls are dropped and evaluated by the coefficient of restitution, and the compression strength and shear strength A method of measuring the compressive strength by sampling from the relationship has been proposed (for example, Patent Document 1).

  Also, a method of measuring the degree of road mass using ultrasonic propagation characteristics has been proposed to measure the degree of mass of an asphalt paved road (see, for example, Patent Document 2).

  However, the conventional methods for confirming the opening of traffic and the method for measuring the degree of solidity of paved roads tend to increase the size and complexity of the confirmation equipment, and to prepare and move the equipment to the construction site. There was a problem that it took a lot of labor and time and was very expensive.

Further, when assuming a wheel load equivalent to a large vehicle, the surface pressure becomes 0.85 to 1 MPa when overloading is assumed, and a load load of 1 MPa must be applied. However, assuming a construction site, there is no jig for applying a 1 MPa load, and it is difficult to judge the opening time of the paved road based on guesses and experiences. It was.

In this method, the ground pressure is applied to the surface of the pavement material after the laying work by an opening confirmation jig comprising at least a plurality of teeth capable of setting a ground pressure and a plate-like member capable of supporting a person's weight. After that, the gist of measuring the amount of excavation at the load point of the contact pressure and comparing the measured value with the reference set value is to determine the opening of traffic on the paved road.

  Here, an opening confirmation jig capable of setting the ground pressure to a range of 0.85 to 1 MPa is used, and the opening confirmation jig is a clog-like footwear.

In addition, a ground contact area of one of the teeth of the release confirmation jig is 0.8 cm ² or more, a display means for measuring the amount of excavation is provided on a side surface of the teeth of the release confirmation jig, and the load of the ground pressure is The amount of digging at the location is measured with a caliper, and the amount of digging is measured 30 seconds after loading the contact pressure with the contact pressure.

  Further, the jig is made of a metal material such as aluminum having a small specific gravity, and the jig has a tooth selected from a square shape, a rectangular shape, and a circular shape. Furthermore, the teeth of the opening confirmation jig can be detached from the plate-like member, and the size of the plate-like member of the opening confirmation jig is 100 mm × 250 mm × 3 mm or more.

  In addition, when the person gets on the surface of the plate-shaped member of the opening confirmation jig, a riding position where a load is uniformly applied to each tooth is displayed. The surface is provided with at least one of a cord, a belt and a band for supporting a person.

  Since the traffic opening confirmation method is performed with such a configuration, anyone can easily determine the traffic opening after laying and constructing the paved road.

  The present invention is a method for confirming the traffic opening of a paved road when opening the paved road after laying and constructing any one of the asphalt paved road, the concrete paved road, and the resin paved road as described above. Then, after loading the ground pressure on the pavement material surface after the laying construction by an opening confirmation jig consisting of at least a plurality of teeth capable of setting the ground pressure and a plate-like member capable of supporting the weight of the person, Measure the amount of excavation at the load point of the contact pressure and compare the measured value with the standard setting value to judge the traffic opening on the paved road, so anyone can open the paved road with simple and inexpensive equipment. There is an effect that can be easily judged.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of an opening confirmation jig used in the traffic opening confirmation method on a paved road according to the present invention, FIG. 2 is a plan view, FIG. 3 is a side view, and FIG. In the figure, the opening confirmation jig 1 includes at least a plurality of teeth 2 (four in this embodiment, but not limited to the number of teeth) that can set the contact pressure with respect to the road surface G of the paved road. And a plate-like member 3 that can support a person's weight. After the contact pressure is applied to the road surface G of the paved road by the opening confirmation jig 1, the amount of digging at the load point of the contact pressure is vernier. The measured value is measured with a measuring instrument such as, and the measured value is compared with a preset reference setting value (the road surface G of the paved road is set to 0) to determine whether the traffic on the paved road is open.

  The opening confirmation jig 1 is preferably made of a material that does not depend on the weight of the person W and is not deformed, for example, a light metal such as aluminum, and the size of the plate-like member 3 (vertical H, horizontal L, high (T: see FIG. 1) is 100 mm × 250 mm × 3 mm or more, and on the surface of the plate-like member 3, when the person W gets on, a riding position X where a load is uniformly applied to each tooth is displayed. It is preferable to provide at least one or more umbilical cord 3a (or a belt, a band, etc.) for supporting a person.

  Furthermore, it is preferable that the teeth 2 of the opening confirmation jig 1 are detachable using one selected from a square shape, a rectangular shape, and a circular shape. Is preferably provided with a display means S such as a scale for measuring the amount of mining.

In addition, the contact pressure with respect to the road surface G of the paved road by the opening confirmation jig 1 assumes a wheel load equivalent to that of a large vehicle, and the surface pressure becomes 0.85 to 1 MPa when overloading is assumed. It is necessary to apply a load load of 1 mm, and by setting so that the ground contact area of one tooth 2 of the opening confirmation jig 1 is 0.8 cm ² or more, the opening as in the embodiment of the present invention is performed. Measurement can be performed by using the confirmation jig 1, and it is possible to determine the opening of traffic on the paved road.

Next, a traffic release confirmation method on a paved road using the release confirmation jig 1 will be described. First, as shown in FIG. 4, when the person W gets on the opening confirmation jig 1, the weight is checked in advance by the measuring instrument 4 so that the weights are uniformly applied to the plurality of teeth 2, and the person W gets on. Ride position X is determined. For example, when a person with a weight of 70 kg gets on and confirms the opening of traffic, an opening confirmation jig 1 provided with four teeth 2 is prepared so that the total contact area is 7 cm ² . From the sense of stability when the person W rides on the plate-like member 3 and the uniformity of the load on the road surface, it is preferable to form four rectangles if possible.

As described above, when the open confirmation jig 1 provided with teeth 2 4, if the contact area of the total 7 cm ^2, at a ground contact area of one 1.75 cm ^2, if it is a square, 1.32 cm It becomes the teeth 2 on all sides. The shape of the tooth 2 is not particularly limited as described above, but is preferably a quadrangular shape or a circular shape, and the ground contact area is preferably 0.8 cm ² or more.

This is because, as the shape of the tooth 2 becomes linear, and when the ground contact area is less than 0.8 cm ² , it is difficult to visually confirm the wrinkles visually and tactilely. Although riding with both feet is more stable, it is preferable to ride with one foot because it is necessary to secure a contact area per tooth 2.

  And after loading the ground pressure by the person W getting on the opening confirmation jig 1 on the road surface G of the paved road, after 30 seconds, the amount of digging at the load point of the ground pressure is measured with a measuring instrument such as a caliper, Compare this measured value with the standard setting value (the road surface G of the paved road is set to 0). If the amount of excavation is 0, the paved road will be cured to a hardness suitable for opening. Judgment of opening.

  As described above, the ground pressure is applied to the surface of the pavement material after laying by the opening confirmation jig 1 including at least a plurality of teeth 2 on which the ground pressure can be set and a plate-like member 3 capable of supporting a person's weight. After the load is measured, the amount of excavation at the load point of the ground pressure is measured, and this measured value is compared with the standard setting value to judge the traffic opening of the paved road, so without using complicated and expensive equipment, Anyone can easily determine the opening of traffic on paved roads with inexpensive equipment.
