When I use curve modifier with array modifier to make a road this happens:

On your file you didn't create any Curve modifier, so nothing happens. Put the Curve modifier below the Array modifier. You'll see that your object is completely swollen. That's because you have somehow played with the vertices radius as you can see in the 3D view T panel if you select the curve, switch to Edit mode and select all. Bring this value back to 1.

Just to expand on @moonboots' answer, because I've been confused by it myself, in the past.

Every vertex on a curve has a radius; in the illustration below, the leftmost vertex has a radius of 3, the rightmost 0.5.

enter image description here

  • (as shown above..) If Curve Normals are displayed, they show the radii.
  • If 'Radius' is checked in the curve's Shape panel, the radii will influence the radial scale of anything following, or deformed by, the curve. You can switch the influence off.
  • In Edit mode, if, as above, you select 1 vertex, the 'Radius' field of the Properties Region > Transform panel will show its radius, and you can adjust its value there.

enter image description here

  • ... if you select more than one vertex, the field becomes 'Mean Radius', and shows the average radius in the selection.

enter image description here

  • If you adjust the Mean Radius (to 1, in the example above), all the radii in the selection are uniformly scaled, so their average becomes the requested value.

enter image description here

  • If you want to set an absolute value for the radius on a selection of vertices, you can do it in the Tool Region > 'Set Curve Radius'.

verify the following

  • first place the array modifier
  • then place the curve modifier
  • select the object in the object list of the curve modifier
  • return to array modifier and increase or decrease the number of segments you need

NOTE: you must apply scale and rotation with CTRL + A to the curve and also to the object, take into account that the result can vary according to the size of the object and the acute angle of the curves

You can follow the configuration that I have in my image so that it fits your model
